CHAPTER 1: INTRODUCTION

About Ceragon MIB

The Ceragon Networks® MIB (Management Information Base) is a set of properties within the device to be managed. Every managed device keeps a database of values for each of the definitions written in the MIB that can be used by management applications to control FibeAir® functions via either the SNMP-V1 or the SNMP-V3 protocols.

The MIB is divided into public and private groups. The private group is owned by Ceragon Networks® and supplements the public group.

The Ceragon MIB supports the following public MIB standards:

● RFC-1213 (MIB II)

● RMON

About this Guide

This guide describes the Private Ceragon MIB for FibeAir IP-10 and the parts of the standard MIBs that Ceragon supports.

The guide is divided into the following chapters:

� Introduction: Provides a general background of the Ceragon MIB, and lists the terms used in this guide.

� Private MIB Structure: A brief explanation of the structure of the Private Ceragon MIB.

� Common Tasks: In this chapter, there is task-oriented detailed explanation, for example, customer that would like to access the unit Current Alarm table, should look in the Current Alarm section of this chapter.

Notes:

� The Ceragon MIB is documented. This document does not replace the Ceragon MIB file, but complements it. Application developers should also get and inspect the latest version of Ceragon MIB file to have a complete and updated understanding on the issues that they want to access in the network element.

� This document only refers to the IP-10 series of Ceragon network.

CHAPTER 3: COMMON TASKS

This chapter provides more thorough information on several common integration tasks that are done by Ceragon customers.

The detailed tasks include:

� General Data

� Current Alarms

� Trap Processing

General Data

Standard MIB Information

Some general info about the network element can be retrieved from the supported standard MIB (RFC1213-MIB):

MIB

Name

Access Description

sysDescr R/O Textual description of the network element

sysObjID R/O � A unique identifier that identifies the product type. The value for the IP-10 series object id is 1.3.6.1.4.1.2281.1.7.1: IP-10

sysUpTime R/O The time (in hundredths of a second) since the network management portion of the system was last re-initialized.

sysContact R/W The textual identification of the contact person for this network element.

sysName R/W An administratively-assigned name for the network element.

By convention, this is the node's fully-qualified domain name.

sysLocation R/W The physical location of this node network element.


Another imported supported standard MIB (RFC1213-MIB) is the ifTable MIB, this table defines the interfaces of the network element, important columns of the table are:

MIB Name Access Description

ifIndex R/O A unique value for each interface. This value is used in many places in Ceragon MIB, to associate data with the interface, one example is in the current alarm table, the value gnAgnCurrentAlarmIfIndex contains the ifIndex of the interface where the alarm occurred.

ifDesc R/O A textual string containing information about the interface.

ifType R/O The type of interface, distinguished according to the physical/link protocol(s) immediately `below' the network layer in the protocol stack.

ifAdminStatus R/W This entry can be used to enable/disable the interface.

ifOperStatus R/O The current operational state of the interface (Up/Down).


Current Alarms

The current alarm table contains all the alarms that are currently raised on the unit. This table presents the data about the alarms, in a slightly more detailed way than the information arriving in the traps from the agent on that alarm’s “raise“ or “clear”. Thus, a monitoring system can use the Alarms Table as a way of synchronization.

An application polling the alarm table should use the genEquipCurrentAlarmLastChangeCounter object (oid 1.3.6.1.4.1.2281.10.3.1.1) in the following manner: upon a polling action, this oid value be retrieved and stored; the polling of the table should only be made if this object’s value differs between the polls.

Note: the application must check for difference (if the retrieved value of the genEquipCurrentAlarmLastChangeCounter differs from the previous - then poll the table), as opposed to "less than", as it is not guaranteed that the genEquipCurrentAlarmLastChangeCounter will always increase in value, being started with a random value.

Note: if an application only needs to know the network element topmost severity (e.g. so it can color the element icon on the application map), then that info can be retrieved from the variable genEquipMostSevereAlarm.

The Ceragon Current Alarm table is a R/O table that contains the following entries:

MIB Name Description

genEquipCurrentAlarmCounter A running counter of “open” alarms, the counter is incremented on every new (Raised) alarm.

It is cleared after reset.

genEquipCurrentAlarmRaisedTimeT

Timestamp of this alarm. This number is the seconds from midnight 1.1.1970. The time zone used is GMT.

genEquipCurrentAlarmId Alarm Id – unique identifier of an alarm. genEquipCurrentAlarmName The name of the alarm genEquipCurrentAlarmInstance The instance of the alarm genEquipCurrentAlarmSeverity

One of: Indeterminate, Warning, Minor, Major or Critical

genEquipCurrentAlarmIfIndex

Interface index on which the alarm has occurred. Alarms that are not associated with a specific interface will have the value 65001 (IDC related alarms). The interface index is used to identify the interface as in the ifTable (See more info in the “Standard MIB Information” section).

genEquipCurrentAlarmModule

IDU or RFU

genEquipCurrentAlarmDesc An informative description of the alarm.

genEquipCurrentAlarmProbableCause The probable cause for the alarm. genEquipCurrentAlarmCorrectiveActions

The corrective actions for the alarm.

genEquipCurrentAlarmState

The state of the alarm (cleared or rasied).

genEquipCurrentAlarmSlotId

The slot originating the alarm. For the IP-10 is constant Zero.


Trap Processing

General Description

When an alarm situation occurs in the unit, it sends a message to the managing station. This message is called a trap.

The unit can be configured to send traps to up to four managers. It is possible to have different configuration for each of the managers, with different Ip, port and severity filters. The unit can be configured to send traps for just alarms, or just events or both.

Note: Alarms have duration, and vary in severity (Indeterminate to Critical). Events do not have duration.

The traps are sent in the same SNP protocol version, as the selected working version. Specifically, setting version = SNMPv3 will lead to the traps being sent in v3, with the SNMP security parameters as set for the agent.


Trap Sending Configuration

Using the genEquipTrapCfgMgrTable, it is possible to configure up to four manages, to which traps will be sent. It is also possible to define trap filters for each of the managers.

Note that the trap community (the community that is sent with the trap) is common to all the managers (it is not possible to configure different trap community per manager).

The entries of the genEquipTrapCfgMgrTable are (“n” represents the manager indices 1..4):

MIB Name Access Description

genEquipTrapCfgMgrId.n R/O This value indicates an index of the nth manager.

genEquipTrapCfgMgrAdmin.n R/W This value indicates an administrative state of the nth manager.

genEquipTrapCfgMgrIP.n R/W The (nth) manager’s IP address.

genEquipTrapCfgMgrPort.n R/W The port number on which the manager will listen for incoming traps (default value is 162).

genEquipTrapCfgMgrName.n R/W The (nth) manager’s name.

genEquipTrapCfgMgrCommunity.n R/W The (nth) manager’s trap community.

genEquipTrapCfgSeverityFilter.n R/W A Bit-mask value filter allowing masking of traps according to their severity using the following logic: There is a bit for each severity. If the relevant bit is on (1), then the Agent will send traps with this severity; won't send otherwise. The list of bits from LSB to MSB: Bit 1 (LSB) - indeterminate Bit 2 - critical Bit 3 - major Bit 4 - minor Bit 5 - warning Bit 6 - cleared

genEquipTrapCfgStatusChangeFilter.n R/W A filter allowing sending of only the traps that change the status of the system (i.e. only when most-severe changes).

genEquipTrapCLLI R/W Common Language Location Identifier (maximum length – 100 characters).

This string is sent in a field in all the traps.

genEquipTrapCfgOptionHeartbeatPeriod R/W The time interval in minutes between heartbeat traps.

Value of 0 disables this feature.


Trap Implementation

Proprietary traps

In IP-10, there are 3 types of proprietary traps:

TRAP TYPE SNMPv1 trap id SNMPv3 trap id

Alarm trap 1001 oid 1.3.6.1.4.1.2281.11.1

Event trap 1002 oid 1.3.6.1.4.1.2281.11.2

Heartbeat trap 1003 oid 1.3.6.1.4.1.2281.11.3

Alarms (for any alarm id) are sent as a single trap type, which is composed of variables that are detailed in the table below. The variables in the trap carry most of the fields from the CurrentAlarm table and described in that section.

The traps structure is the same for both SNMPv1 and SNMPv3 traps∗.

The general (alarm) trap variables are:

• genEquipCurrentAlarmCounter

• genEquipCurrentAlarmRaisedTimeT

• genEquipCurrentAlarmId

• genEquipCurrentAlarmSlotId

• genEquipCurrentAlarmInstance

• genEquipCurrentAlarmSeverity

• genEquipCurrentAlarmIfIndex

• genEquipCurrentAlarmModule

• genEquipCurrentAlarmDesc

• genEquipMostSevereAlarm

• genEquipAgentIp

• genEquipCurrentAlarmState

• genEquipTrapCfgMgrCLLI

The “event” type traps have the exact same variable binds, except the “genEquipCurrentAlarmState” value – that one is not relevant for events.

The “heartbeat” type traps only carry the “genEquipTrapCfgMgrCLLI” variable.

Traps may be used for updating the alarm status in northbound management systems. As noted above, the variables in the trap are the same as the in the current alarm table. In addition, the genEquipCurrentAlarmLastChangeCounter helps to determine periodically if another polling of the CurrentAlarms table is required or if the situation as presentedby using the incoming traps is accurate and up to date.

The combination of “genEquipCurrentAlarmId”, “genEquipCurrentAlarmInstance”, “genEquipCurrentAlarmIfIndex” and “genEquipCurrentAlarmSlotId” values (all Integer values), serves as the unique key for making the correlation between the CurrentAlarm table values and the traps.

∗ In order to be able to have backward compatibility with the old MIB and be able to receive traps from earlier IP-10 release

(6.0) products, the old trap definition has been kept (trap id 1); However, from the current release on, the traps have structure as defined here.


Standard Traps

Standard generic traps are: coldStart, warmStart, linkDown, linkUp, authenticationFailure, egpNeighborLoss.

In the current release, 5 of the 6 existing types are supported. EGP is not implemented and thus the 6th type is irrelevant.

Cold Start – generated upon a HW reset of the system. Varbinds include:

• enterpriseId

Warm Start – generated upon a SW reset of the system. Varbinds include:

• enterpriseId

LinkDown – generated upon setting the Admin param to “disable” or in cases of erroneous

behaviour. Varbinds include:

• ifIndex

• ifAdminStatus

• ifOperStatus1

• enterpriseId

LinkUp – generated upon setting the Admin param to “enable” or in cases of exiting

erroneous situation in cases of enabled Admin. Varbinds include:

• ifIndex

• ifAdminStatus

• ifOperStatus

AuthenticationFailure – generated by the master agent in cases of wrong community-based authentication.

1 Please note the definitions of ifOperStatus (and ifAdminStatus) in the standard traps are slightly different than how DMAE

defines and uses them. Particularly, the MIB status parameters have additional states which DMAE doesn’t support.
