2 Overview
2.1 Introduction
With the advent of Internet Protocol (IP) transformation in telecom operator networks, Ethernet
bearer networks are widely used. To guarantee the reliability and availability of Ethernet
services, the Ethernet OAM feature is introduced.
This feature provides detection, notification, verification, and locating functions for detectable
hard faults (such as link disconnection) or undetectable soft faults (such as damages in memory
bridges).
From this version onwards, , Ethernet OAM supports three protocols: point-to-point IEEE
802.3ah, end-to-end IEEE 802.1ag, and ITU-T Y.1731.
2.2 Benefits
The Ethernet OAM feature provides the following benefits:
l Helps improve operators' capabilities of managing and maintaining the Ethernet.
l Guarantees network reliability.
l Reduces the operating expense (OPEX).
2.3 Architecture
The Ethernet OAM feature detects and reports the network status at the data link layer to
efficiently monitor and manage the Ethernet. Figure 2-1 shows the position of the Ethernet OAM
protocols in the OSI model.

3 Ethernet OAM (IEEE 802.3ah)
3.1 Introduction
Ethernet OAM (IEEE 802.3ah) is a point-point Ethernet OAM protocol used to implement the
Ethernet in the First Mile (EFM) OAM function. With this function, the link status is monitored
effectively.
The EFM OAM function must be enabled for two pieces of equipment that are directly connected
during point-point Ethernet OAM services. The function detects faults on Ethernet links by using
the automatic discovery, fault detection, link monitoring, and remote loopback mechanisms.
After Ethernet OAM (IEEE 802.3ah) is deployed between a base station (or base station
controller) and transmission equipment that is dir ectly connected to the Ethernet interface, OAM
Protocol Data Units (PDUs) are exchanged between the local end and remote end to detect the
link status, as shown in Figure 3-1 However, the remote transmission equipment must support
IEEE 802.3ah.
Figure 3-1 Ethernet OAM (IEEE 802.3ah)
3.2 Principles
Ethernet OAM (IEEE 802.3ah) supports active and passive modes.
l In active mode, the local end sends negotiation packets to the remote end.
l In passive mode, the local end waits for negotiation packets from the remote end.

3.4 Technical Description
The IEEE 802.3ah protocol defines four basic functions: automatic discovery, fault detection,
link monitoring, and remote loopback. Automatic discovery is a process of establishing and
interacting OAM sessions and is the prerequisite for other OAM functions. Link monitoring,
fault detection, and remote loopback are used to monitor network performance and locate link
failures.
Automatic Discovery
Automatic discovery is the first phase for the implementation of Ethernet OAM (IEEE 802.3ah).
For example, if the radio equipment works in active mode and the transmission equipment works
in passive mode, the two ends exchange OAM PDUs to obtain their respective OAM support
capabilities, as shown in Figure 3-3.
Figure 3-3 Automatic discovery procedure
Fault Detection
l When the local end is faulty, the local OAM client notifies the remote OAM client of the
fault by sending an OAM PDU that contains the fault information.
l When the remote end is faulty, the remote OAM client notifies the local OAM client of the
fault by sending an OAM PDU that contains the fault information.

Link Monitoring
Link monitoring is used to monitor bit errors, such as errored frames and errored signals on a
link. When the bit error rate (BER) exceeds a specified threshold, the local OAM client notifies
the remote OAM client of the corresponding bit error event by sending an Event NotificationOAM PDU. Then, the remote OAM client reports the link fault to the local OAM client.
To measure the performance from different perspectives, the link monitoring function is divided
into errored frame event monitoring, errored frame seconds event monitoring, and errored frame
period event monitoring.
l Errored frame event monitoring: The errored frame event monitoring period refers to the
period in which errored frames are measured once. In this period, the number of detected
errored frames is greater than or equal to the specified errored frame event threshold. The
related parameters in GSM, UMTS, and LTE modes are as follows:
NE Parameter Name Parameter ID

NOTE
l The GBTS and eGBTS use different MML commands, and therefore they may use different
parameter IDs and names.
l Unless otherwise specified, "base station controller" in this document is a generic term for GSM
and UMTS modes.
l Errored frame seconds event monitoring: In an errored frame seconds summary event
period, the number of detected errored frame seconds is greater than or equal to the specifiederrored frame seconds summary event threshold. An errored frame seconds event indicates
that at least one errored frame is detected in a second. The related parameters in GSM,
UMTS, and LTE modes are as follows:

Remote Loopback
In a remote loopback, the local OAM client sends packets to the remote OAM client, and the
remote OAM clients loops back packets other than non-OAM PDUs. The remote loopback
function can be used to locate link faults and check link quality.
The local OAM client sends a Loopback Control OAM PDU to the remote OAM client,
instructing it to enter the loopback state. As shown in Figure 3-4, after the remote OAM client
enters the loopback state, the local OAM client sends packets to the remote OAM client and
then calculates the packet loss rate and other KPIs on the current link based on the number of
sent and received packets.
Figure 3-4 Remote loopback
Only the port in active mode can initiate a remote loopback. The remote loopback function can
be enabled on a port only if both the following conditions are met:

l The port works in active mode.
l The port and the peer port work properly.
Assuming that the local OAM client is radio equipment and the remote OAM client is
transmission equipment, the remote loopback function is implemented as follows:
1. The radio equipment sends a Loopback Control OAMPDU with the Enable OAM Remote
Loopback command to the transmission equipment.
2. Upon receiving the Loopback Control OAMPDU, the transmission equipment responds
with an Information OAMPDU with updated state message to the radio equipment and
enters the loopback state.
3. The radio equipment enters the loopback state if it receives the Information OAMPDU with
updated state from the transmission equipment within a specified period. The radio
equipment sends the Loopback Control OAMPDU with the Enable OAM Remote
Loopback command again if it has not received the Information OAMPDU with updated
state from the transmission equipment within the specified period. The radio equipment
can send the command three consecutive times at most.
4. If the radio equipment needs to terminate the remote loopback, it sends a Loopback Control
OAMPDU with the Disable OAM Remote Loopback command to the transmission
equipment. Upon receiving the command, the transmission equipment exits the loopback
state.

4 Ethernet OAM (IEEE 802.1ag)
4.1 Introduction
The Ethernet OAM (IEEE 802.1ag) is an end-to-end Ethernet OAM protocol used to implement
the Connectivity Fault Management (CFM) function. The CFM function is a network-level
Ethernet OAM technology and comprises continuity check, loopback, and linktrace functions.
With the CFM function, the continuity faults on the entire network can be detected and located.
If the base station or base station controller detects Ethernet faults or undesirable network
performance using Ethernet OAM (IEEE 802.1ag), it initiates rerouting, port switchover, or
board switchover if necessary, to ensure normal connection of Ethernet links.
4.2 Principles
Ethernet OAM (IEEE 802.1ag) reports the status of the data link layer and therefore effectively
monitors and manages the network. To enable Ethernet OAM (IEEE 802.1ag), the local end and
remote end on the network must support IEEE 802.1ag.
To implement end-to-end Ethernet link maintenance and fault detection and isolation, Ethernet
OAM (IEEE 802.1ag) defines Maintenance Domain (MD), Maintenance Association (MA),
Maintenance Point (MP), Maintenance End Point (MEP), and Maintenance Intermediate Point
(MIP).
Ethernet OAM (IEEE 802.1ag) implements the service-based end-to-end detection. In addition,
it detects the network segments along the same service flow one by one.
l MD
The maintenance domain name is specified by the MDNAME parameter and denotes a
network or a part of a network in which the CFM is implemented. An MD is usually
managed by an Internet Service Provider (ISP) or an operator.
MDs can be managed on a per level basis. The level of an MD is specified by the Level
parameter. A high-level MD can span low-level MDs, but a low-level MD cannot span
high-level MDs. This level-based MD management allows the same service flow to be
maintained segment by segment and also applies to different service flows.

Ethernet OAM (IEEE 802.1ag) supports eight MD levels, ranging from 0 to 7. Level 7 is
the highest MD level, and level 0 is the lowest.
l MA
An MD can be divided into one or more MAs. The continuity of each MA can be checked
using the CFM function.
In networks of operators, one Virtual Local Access Network (VLAN) generally
corresponds to one service instance and one MA. Therefore, the continuity check of service
instances can be performed on a per MA basis.
l MEP
MEPs are end points of MAs. In an MA, MEPs on the radio equipment that supports IEEE
802.1ag are defined as local MEPs and those on other equipment are defined as remote
MEPs.
l MIP
MIPs are intermediate points of MAs.All OAM operations are initiated by MEPs. MIPs do not actively initiate any OAM
operation or send any OAM packets.
Figure 4-1 shows the relationship among MD, MA, MEP, MIP, and VLAN. The local and
remote ends are configured in the same MD. The MD is divided into two MAs, MA 1 and MA
2. MA 1 contains MEPID 1 configured on the Lport1 and MEPID 2 configured on the Rport2.
MA 2 contains MEPID 1 configured on the LPort2 and MEPID 2 configured on the RPort1. The
IDs of MEPs in different MAs can be the same.
In this example, LPort1 and LPort2 serve as local MEPs, and the RPort1 and RPort2 serve as
remote MEPs.
Figure 4-1 Relationship among MD, MA, MEP, MIP, and VLAN
NOTE
The radio equipment can work as an MEP but cannot work as an MIP.
The MEPs at different MD levels process OAM packets as follows:
l MEPs transparently transmit the OAM packets from a higher MD level.

l MEPs discard the OAM packets from a lower MD level.
l MEPs respond to or terminate the OAM packets from the same MD level based on the
OAM packet type.
4.3 Application Scenarios
Figure 4-2 shows a network topology when Ethernet OAM (IEEE 802.1ag) is used. Ethernet
OAM (IEEE 802.1ag) is deployed between GBTS/NodeB/eNodeB/eGBTS and transmission
equipment, and between BSC/RNC and transmission equipment.
Figure 4-2 Network topology with Ethernet OAM (IEEE 802.1ag) enabled
4.4 Technical Description
Ethernet OAM (IEEE 802.1ag) implements end-to-end Ethernet maintenance and detection
using the following functions:
l Continuity check (CC)
l
Loopback (LB)l Linktrace (LT)
l CC
CC is one of basic functions provided by Ethernet OAM (IEEE 802.1ag) and can be used
to check the continuity of Ethernet links between MEPs on two pieces of Ethernet
equipment.
After this function is enabled, each MEP in an MD periodically sends CCM packets and
all MEPs in the same MD can receive the CCM packets. However, these MEPs do not need
to respond to the received CC packets. After receiving a CCM packet from the remote MEP,
the local MEP starts to measure the number of periods of sending CCM packets. Within
three consecutive periods (The period is the same as the period of sending CCM packets
from the remote MEP. The local MEP uses the same period of sending CCM packets as
the remote MEP), if the local MEP does not receive any CCM packet from the remote MEP,
the local MEP determines that a continuity fault occurs between both ends.
l LB
LB is used to detect the bidirectional continuity between the local end and remote end.
– The local MEP sends a Loopback Message which contains the MAC address or MEP
ID of the destination MP (MEP or MIP) and meanwhile starts a timer. If the destination
MP responds with a Loopback Return message to the local MEP after receiving the
Loopback Message, the loopback is successful.
– If the local MEP does not receive the Loopback Return message from the destination
MP before the timer specified by the local MEP expires, the loopback fails.

http://slidepdf.com/reader/full/ethernet-oamsran8003pdf 21/115
The LB is similar to the Ping operation and therefore is also called MAC PING.
l LT
LT is used to retrieve the MP adjacency and locate faults. The local MEP sends a Link
Trace Message which contains the MAC address or MEP ID of the destination MEP and
meanwhile starts a timer. All MIPs in the same MD as the local MEP on the link receive
the Link Trace Message and then forward the message to the destination MEP. Upon
receiving the Link Trace Message, the destination MEP responds with a Link Trace Reply
message to the local MEP.
– If the destination MEP terminates the Link Trace Message and returns a Link Trace
Reply to the local MEP, the link trace is successful.
– If the local MEP does not receive the Link Trace Reply message from the destination
MEP before the timer specified by the local MEP expires, the link trace fails.
NOTE
The LT function cannot be enabled for links between the local MEP and MIPs.
In addition, the Link Trace Reply message contains Time to Live (TTL) parameters which
specify the position of the MP that responds with the message on the tested link.
LT is similar to TraceRoute and therefore is also called MAC TRACE.

5 Ethernet OAM (ITU-T Y.1731)
5.1 Introduction
Ethernet OAM (ITU-T Y.1731) is an enhancement of Ethernet OAM (IEEE 802.1ag). In addition
to the CFM function specified by IEEE 802.1ag, Ethernet OAM (ITU-T Y.1731) implements
the Performance Management function. The Performance Management function allows the base
station to perform single-ended Ethernet Loss Measurement (ETH-LM), two-way Ethernet
Delay Measurement (ETH-DM), and delay variation measurement.
Ethernet OAM (TU-T Y.1731) is defined by ITU-T Y.1731 (2008). In GSM and UMTS modes,
Ethernet OAM (ITU-T Y.1731) is supported only on the base station side.
5.2 Principles
The working principle for Ethernet OAM (ITU-T Y.1731) is similar to that for Ethernet OAM
(IEEE 802.1ag). The only difference is as follows:
Ethernet OAM (ITU-T Y.1731) incorporates the following changes:
l Combines MDs and MAs into a Maintenance Entity Group (MEG).
l Replaces the MA ID with MEG ID.
l Replaces MD level with MEG Level.
The definitions of MEPs, MIPs are the same in Ethernet OAM (ITU-T Y.1731) and Ethernet
OAM (IEEE 802.1ag).
5.3 Application Scenarios
Figure 5-1 shows a network topology when Ethernet OAM (ITU-T Y.1731) is used. Ethernet
OAM (ITU-T Y.1731) is deployed between a base station and transmission equipment and both
ends must support ITU-T Y.1731.

5.4 Technical Description
Ethernet OAM (ITU-T Y.1731) inherits the CFM function from Ethernet OAM (IEEE 802.1ag).
For details about the CFM function, see section 4.4 Technical Description. This section
describes the Performance Management function of Ethernet OAM (ITU-T Y.1731), which is
used for single-ended ETH-LM, two-way ETH-DM, and delay variation measurement.
When single-ended ETH-LM and two-way ETH-DM of Ethernet OAM (ITU-T Y.1731) are
supported, the base station supports only one of the following monitoring policies, not their
combinations:
l PORTID_VLANID (measurement based on PortID and VLAN ID)
l PORTID_VLANID_VLANPRI (measurement based on PortID, VLAN ID, and VLAN
PRI)
l SA_DA_VLANID (measurement based on PortID, SA, DA, and VLAN ID)
l SA_DA_VLANID_VLANPRI (measurement based on PortID, SA, DA, VLAN ID, andVLAN PRI)
l SA_DA (measurement based on PortID, SA, and DA)
PortID, VLANID, VLAN PRI, SA, and DA indicate the port ID, VLAN ID, VLAN priority,
source MAC address, and destination MAC address, respectively.
NOTE
The monitoring policy for the Performance Management function must be supported by the base station
as well as the peer transmission equipment.
Single-ended Ethernet Loss Measurement (ETH-LM)
Single-ended ETH-LM is used for on-demand OAM. LMM and LMR messages contain values
of counters for frame loss measurements.
Each MEP on the base station side can measure the following items:
l Local-end frame loss: loss of service frames in the downlink
l Remote-end frame loss: loss of service frames in the uplink
During a single-ended ETH-LM, an MEP on the base station side sends an LMM request message
to its peer MEP on the transmission equipment and receives an LMR message from its peer
MEP. If the LMM request message indicates that the value of the local counter TxFCf is TxFCf
[tc], the transmission equipment responds with an LMR message, as shown in Figure 5-2. An
LMM message contains the counter values as described in Table 5-1.

TxFCf Local counter at the time of LMM message transmission
RxFCf Remote counter at the time of LMM message reception
TxFCb Remote counter at the time of LMR message transmission
RxFCl Local counter RxFCl at the time of LMR message reception
Upon receiving the LMR message, the base station use the following values contained in the
message for local- and remote-end loss measurements:
l The respective values of the TxFCf, RxFCf, and TxFCb counters are TxFCf[tc], RxFCf
[tc], and TxFCb[tc] when the base station receives the LMR message. In this message, the
value of the local counter RxFCl is RxFCl[tc].
NOTE
The "tc" in the RxFCl[tc] indicates the time when the base station receives the current LMR message.
l The respective values of the TxFCf, RxFCf, and TxFCb counters are TxFCf[tp], RxFCf
[tp], and TxFCb[tp] when the base station receives the previous LMR message. In this
message, the value of the local counter RxFCl is RxFCl[tp].
NOTE
The "tp" in the RxFCl[tp] indicates the time when the base station receives the previous LMR message.
Based on the preceding values carried in LMR messages, the remote-end frame loss (in the
uplink) is calculated using the following formula:
Remote-end frame loss = (TxFCf[tc] – TxFCf[tp]) – (RxFCf[tc] – RxFCf[tp])

The local-end frame loss (in the downlink) is calculated using the following formula:
Local-end frame loss = (TxFCb[tc] – TxFCb[tp]) – (RxFCl[tc] – RxFCl[tp])
Two-Way ETH-DM
In two-way ETH-DM, if the local MEP sends a DMM frame with the TxTimeStampf value to
the remote MEP, and the remote MEP delays responding with a DMR frame, the delay will be
used as the delay for the entire L2 network. Figure 5-3 shows the detailed message exchanges
between the local MEP and remote MEP. The counters for ETH-DM are described in Table
5-2.
Frame delay = (RxTimeb – TxTimeStampf) – (TxTimeStampb – RxTimeStampf)
Figure 5-3 Message exchange for two-way ETH-DM
Table 5-2 Counters for two-way ETH-DM
Counter Description
TxTimeStampf Local timestamp at the time of DMM transmission from the local MEP
RxTimeStampf Local timestamp at the time of DMM reception by the remote MEP
TxTimeStampb Local timestamp at the time of DMR transmission from the remote MEP
RxTimeb Local timestamp at the time of DMR reception by the local MEP
The frame delay variation can be calculated using the following formula:
Frame delay variation = Frame delay[tc] – Frame delay[t p]

System Capacity No impact.
Network Performance
Ethernet OAM protocols are slow protocols and therefore can provide low data rate functions,
such as the ping function. In addition, Ethernet OAM protocols occupy low bandwidth and
therefore do not affect the data flow of other services. If the CCM function is enabled, packets
must be sent at an interval of at least one second because sending packets at a very short interval
affects the performance of transport networks.
When the remote loopback function provided by Ethernet OAM (IEEE 802.3ah) is enabled,
services carried on a base station are interrupted.

8 Engineering Guidelines
8.1 When to Use Ethernet OAM
Before Ethernet OAM is enabled, the following conditions must be met:
l Both the base station or base station controller and the transport network are borne by a L2
Ethernet.
l The transmission equipment supports Ethernet OAM.
Ethernet OAM (IEEE 802.3ah) is an effective link monitoring and fault detection mechanism
during point-to-point Ethernet OAM (only for the base station side). It is recommended that
Ethernet OAM (IEEE 802.3ah) be deployed for a base station or base station controller and
adjacent transmission equipment that supports IEEE.802.3ah.
Ethernet OAM (IEEE 802.1ag) is used to detect and maintain the continuity of end-to-end
Ethernet links. This feature implements service-based end-to-end continuity check per MD and
manages the network segments along the same service flow one by one. In addition, this feature
provides link detection and route interlock functions. It is recommended that Ethernet OAM
(IEEE 802.1ag) be deployed for a base station or base station controller and transmission
equipment that supports IEEE 802.1ag.
If frame loss and delay variation measurements are required for end-to-end Ethernet links, you
are advised to deploy Ethernet OAM (ITU-T Y.1731).
In base station co-transmission scenarios, Ethernet OAM is deployed only for a base station thatdirectly is connected to the transport network. Ethernet OAM is deployed only for a mode of a
base station if multiple modes of the base station are directly connected to the transport network.
Therefore, engineering guidelines for Ethernet OAM are described per base station mode.

NOTE
The GBTS and eGBTS use different MML commands, and therefore they may use different parameter IDs
and names.
Unless otherwise specified, "base station controller" in this document is a generic term for GSM and UMTS
modes.
l eGBTS refers to a base station deployed with UMPT_G.
l NodeB refers to a base station deployed with WMPT or UMPT_U.
l eNodeB refers to a base station deployed with LMPT or UMPT_L.
l Co-MPT multimode base station refers to a base station deployed with UMPT_GU, UMPT_GL,
UMPT_UL, or UMPT_GUL, and it functionally corresponds to any combination of eGBTS, NodeB,
and eNodeB. For example, Co-MPT multimode base station deployed with UMPT_GU functionally
corresponds to the combination of eGBTS and NodeB.
l Separate-MPT multimode base station refers to a base station on which different modes use different
main control boards. For example, base stations deployed with GTMU and WMPT are called separate-
MPT GSM/UMTS dual-mode base station.
8.2 Required Information
To deploy Ethernet OAM, collect the following information:
l Whether the transmission equipment supports Ethernet OAM.
l The IEEE 802.1ag version (Draft 7 or standard version) supported by the transmission
equipment during Ethernet OAM (IEEE 802.1ag) deployment
l Whether the transmission equipment supports ITU-T Y.1731 (2008) during Ethernet OAM
(ITU-T Y.1731) deployment
The protocol version supported by the transmission equipment must be the same as thatsupported by the radio equipment.
The following table describes the versions for IEEE 802.1ag and ITU-T Y.1731 protocols
supported by the radio equipment.
Protocol GBTS/NodeB/eNodeB/eGBTS BSC/RNC
IEEE 802.1ag
NOTE
IEEE 802.1ag is
incompatible with its
draft version or EEE802.1ag (2007).
Therefore, both ends
must use the same
protocol version.
From GBSS9.0/RAN9.0 to
GBSS13.0/RAN13.0, the base
station supports only IEEE 802.1ag
(Draft 7). From GBSS14.0/
RAN14.0/eRAN3.0/SRAN7.0, the base station supports only the
standard version.
The base station controller
supports both the Draft 7 and
standard version.
ITU-T Y.1731 The base station supports ITU-T Y.
1731 (2008).
The base station controller
does not support ITU-T Y.
1731 (2008).
When deploying Ethernet OAM (IEEE 802.1ag) or Ethernet OAM (ITU-T Y.1731), plan the
following data for the base station (or base station controller) and transmission equipment:

to activate a feature on existing NodeBs. This method reconfigures all data, except neighbor
relationships, for multiple NodeBs in a single procedure. The procedure is as follows:
Step 1 Choose CME > Advanced > Customize Summary Data File from the main menu of an M2000
client, or choose Advanced > Customize Summary Data File from the main menu of a CME
client, to customize a summary data file for batch reconfiguration.
NOTE
For context-sensitive help on a current task in the client, press F1.
Step 2 Export the NE data stored on the CME into the customized summary data file.
l For co-MPT multimode base stations: Choose CME > SRAN Application > MBTS

8.7.5 Activation
This section uses the scenario shown in Figure 4-2 as an example and describes how to activate
Ethernet OAM (IEEE802.1ag) using the MML and CME GUI.
NOTE
l Enable Ethernet OAM (IEEE802.1ag) simultaneously on the base station and transmission equipment.
l Enable Ethernet OAM (IEEE802.1ag) simultaneously on the base station controller and transmission
equipment.
Using MML Commands
On the BSC side
Step 1 Run the ADD CFMMD command to add a CFM MD. In this step, set the following parameters
to appropriate values:l MD Index
l MD Level
l MD Name
Step 2 Run the ADD CFMMA command to add an MA. In this step, set the parameters as follows:
l Set MD Index, VLAN ID, MA Index, and MA Name to appropriate values.
l Set CCM Send Prid to a period of sending CCM packets in the MA.
Step 3 Run the ADD CFMMEP command to add a local MEP. In this step, set MEP Type to LocalMep
(LocalMep).
Step 4 Run the ADD CFMMEP command to add a remote MEP. In this step, set MEP Type to
RemoteMep(RemoteMep) .
----End
The preceding steps are used for configuration. The following steps are used for continuity check
and performance management.
l Run the ACT CFMCCMTST command to activate the CC function at a specified local
MEP.
l Run the PING MAC command to start a MAC PING test on the BSC side. During the
implementation of the MAC PING test, ensure that the CC function is enabled at the localMEP and remote MEP so that the local MEP can obtain the MAC address of the remote
MEP.
l Run the TRC MAC command to start a MAC TRACE test on the BSC side. During the
implementation of the MAC TRACE test, ensure that the CC function is enabled at the
local MEP and remote MEP so that the local MEP can obtain the MAC address of the
remote MEP.
On the GBTS side
Step 1 IEEE 802.1agITU-T Y.1731Run the SET BTSETHOAM command with OAM Type set to
IEEE 802.1ag or ITU-T Y.1731. If this parameter is set to ITU-T Y.1731, Monitor Policy
must be configured.

Step 2 Run the ADD BTSETHMD command to add a CFM MD.
NOTE
When OAM Type is set to ITU-T Y.1731, MDNAME is invalid, and MEG LEVEL equals to MD LEVEL
in IEEE 802.1ag.
Step 3 Run the ADD BTSETHMA command to add an MA.
NOTE
When OAM Type is set to ITU-T Y.1731, MANAME equals to MEG ID in IEEE 802.1ag. If the GBTS
is interconnected with peer equipment, MANAME must be consistent with the MEG ID of the peer NE.
Step 4 Run the ADD BTSETHLCMEP command to add a local MEP.
Step 5 Run the ADD BTSETHRMMEP command to add a remote MEP.
----End
The preceding steps are used for configuration. The following steps are used for continuity check
and performance management.
l Run the ACT BTSETHCC command to activate the CC function at a specified local MEP.
l Run the PING BTSCFM command to start a MAC PING test on the GBTS side. During
the implementation of the MAC PING test, ensure that the CC function is enabled at the
local MEP and remote MEP so that the local MEP can obtain the MAC address of the
remote MEP.
l Run the TRC BTSCFM command to start a MAC TRACE test on the GBTS side. During
the implementation of the MAC TRACE test, ensure that the CC function is enabled at the
local MEP and remote MEP so that the local MEP can obtain the MAC address of the
remote MEP.
If Ethernet OAM (ITU-T Y.1731) is activated:
l Run the ACT BTSETHLM command to activate the single-ended ETH-LM function at a
specified local MEP.
l Run the ACT BTSETHDM command to activate the two-way ETH-DM function at a
specified local MEP.
On the eGBTS side
The procedure for activating Ethernet OAM (IEEE802.1ag) or Ethernet OAM (ITU-TY.1731)
using MML commands on the eGBTS side is the same as that on the NodeB side. For details,
see "On the NodeB side" in Using MML Commands in section 8.8.5 Activation.

Using the CME to Perform Batch Configuration
Neither the BSC nor GBTS supports using CME batch configuration to activate Ethernet OAM
(IEEE 802.1ag/ITU-TY.1731), but the eGBTS does. The CME batch configuration for an
eGBTS is the same as that for a NodeB. For details, see Using the CME to Perform Batch
Configuration in section 8.8.5 Activation.
8.7.6 Activation Observation
Using MML Commands
On the BSC side
Before using the following methods, ensure that the CC function is enabled at the local and
remote ends.
Method 1: Run the DSP CFMMEP command to query the status and MAC address of the remote
MEP. If the value of MAC Address is that of the remote port, Ethernet OAM (IEEE 802.1ag)
or Ethernet OAM (ITU-T Y.1731) has been activated.Method 2: Run the PING MAC or TRC MAC command to start an LB or LT test from the
local MEP to the remote MEP. If the MAC address of the remote MEP is pinged through,
Ethernet OAM (IEEE 802.1ag) or Ethernet OAM (ITU-T Y.1731) has been activated. If the
MAC address of the remote MEP cannot be pinged through, Ethernet OAM (IEEE 802.1ag) or
Ethernet OAM (ITU-T Y.1731) has not been activated.
On the GBTS side
Before using the following method, ensure that the CC function is enabled at the local and remote
ends.
Run the PING BTSCFM or TRC BTSCFM command to start an LB or LT test from the local
MEP to the remote MEP. If the MAC address of the remote MEP is pinged through, Ethernet

NOTE
When OAM Type is set to ITU-T Y.1731, MANAME equals to MEG ID in IEEE 802.1ag. If the GBTS
is interconnected with peer equipment, MANAME must be consistent with the MEG ID of the peer NE.
Step 4 Run the ADD CFMMEP command to add a local MEP.
Step 5 Run the ADD CFMRMEP command to add a remote MEP.
Step 6 Run the ADD CFMBNDIP command to add a CFM binding IP address of the remote MEP to
implement the route interlock.
----End
The preceding steps are used for configuration. The following steps are used for continuity check
and performance management.
l Run the ACT CFMCC command to activate the CC function at a specified local MEP.
l
Run the CFMPING command to start the CFM MAC PING test on the NodeB side. Duringthe implementation of the MAC PING test, ensure that the CC function is enabled at the
local MEP and remote MEP so that the local MEP can obtain the MAC address of the
remote MEP.
l Run the CFMTRACE command to start the CFM MAC TRACE test on the NodeB side.
During the implementation of the MAC TRACE test, ensure that the CC function is enabled
at the local MEP and remote MEP so that the local MEP can obtain the MAC address of
the remote MEP.
If Ethernet OAM (ITU-T Y.1731) is activated:
l Run the ACT ETHLM command to activate the single-ended ETH-LM function at a
specified local MEP.l Run the ACT ETHDM command to activate the two-way delay variation measurement
function at a specified local MEP.

8.8.6 Activation Observation
Using MML Commands
On the RNC side
Before using the following methods, ensure that the CC function is enabled at the local and
remote ends.
Method 1: Run the DSP CFMMEP command to query the status and MAC address of the remote
MEP. If the value of MAC Address is that of the remote port, Ethernet OAM (IEEE 802.1ag)
or Ethernet OAM (ITU-T Y.1731) has been activated.
Method 2: Run the PING MAC or TRC MAC command to start an LB or LT test from the
local MEP to the remote MEP. If the MAC address of the remote MEP is pinged through,
Ethernet OAM (IEEE 802.1ag) or Ethernet OAM (ITU-T Y.1731) has been activated. If the
MAC address of the remote MEP cannot be pinged through, Ethernet OAM (IEEE 802.1ag) or Ethernet OAM (ITU-T Y.1731) has not been activated.
On the NodeB side
Before using methods 1 and 2, ensure that the CC function is enabled at the local and remote
ends.
Method 1: Run the DSP CFMRMEP command to query the status and MAC address of the
remote MEP. If value of the Actual MAC Address is that of the remote port and the value of
Status is Normal, the remote MEP is in normal state and Ethernet OAM (IEEE 802.1ag) or
Ethernet OAM (ITU-T Y.1731) has been activated.
Method 2: Run the CFMPING or CFMTRACE command to start an LB or LT test from thelocal MEP to the remote RMEP. If the MAC address of the remote MEP is pinged through,
Ethernet OAM (IEEE 802.1ag) or Ethernet OAM (ITU-T Y.1731) has been activated. If the
MAC address of the remote MEP cannot be pinged through, Ethernet OAM (IEEE 802.1ag) or
Ethernet OAM (ITU-T Y.1731) has not been activated.
Before using method 3, you do not need to enable the CC function.
Method 3: If you have obtained the MAC address of the remote MEP, run the CFMPING or
CFMTRACE command to check the continuity between the local MEP and the remote MEP.
8.8.7 Reconfiguration
If the base station supports IEEE 802.1ag or ITU-T Y.1731 and you need to change the
configuration of Ethernet OAM (IEEE 802.1ag) to the configuration of Ethernet OAM (ITU-T
Y.1731), you must delete the configured MDs, MAs, MEPs, and RMEPs for Ethernet OAM
(IEEE 802.1ag) first.
The following steps are used to change the configuration of Ethernet OAM (IEEE 802.1ag) to
the configuration of Ethernet OAM (ITU-T Y.1731):
On the NodeB side
Step 1 Run the RMV CFMBNDIP command to delete a CFM binding IP address of the remote MEP,
which is used to implement the route interlock.
Step 2 Run the RMV CFMRMEP command to delete a remote MEP.

Step 3 Run the RMV CFMMEP command to delete a local MEP.
Step 4 Run the RMV CFMMA command to delete an MA.
Step 5 Run the RMV CFMMD command to delete a CFM MD.
Step 6 To change the configuration of Ethernet OAM (IEEE 802.1ag) to the configuration of Ethernet
OAM (ITU-T Y.1731) on the NodeB side, do as follows:
Run the SET ETHOAM command with OAM Type set to ITU_T_Y1731(ITU-T Y.1731).
If you need to change the configuration of Ethernet OAM (ITU-T Y.1731) to the configuration
of Ethernet OAM (IEEE 802.1ag), perform the similar operation.

8.12 Troubleshooting On the BSC or RNC side
If link faults occur or the remote end does not support the Ethernet OAM feature, OAM discovery
fails. In this case, ALM-21371 ETHOAM 3AH Detection Failure alarm is reported. You can
troubleshoot the problem following the steps provided in the alarm help.
After the remote loopback function provided by Ethernet OAM (IEEE 802.3ah) is enabled by
running the BSC/RNC MML command STR EFMLOOPTST, if the remote loopback succeeds,
ALM-21374 ETHOAM 3AH Remote Loopback is reported due to service congestion. This
alarm is cleared when the remote loopback test ends.
