CAPWAP WG MIB Drafts Report

Current Work Status CAPWAP Base MIB CAPWAP Dot11 Binding MIB Open Issue Next Step

Agenda

Since IETF 72th meeting, we have published three versions for CAPWAP base MIB. Now, latest version is 03. Also, we have published two versions for Dot11 binding MIB. Now, latest version is 02.

Yong Zhang has joined MIB work and became one of co-editors.

Current Work Status

Current Work Status CAPWAP Base MIB CAPWAP Dot11 Binding MIB Open Issue Next Step

Agenda

Changes between 00 and 01The main work is to make MIB model consistent with base protocol and improve draft’s readability.1) Closed all review comments from Dan.2) To improve readability, we updated the section 5

Overview, 7.2 Relationship to the IF-MIB, 7.3 Relationship to the ENTITY-MIB.

CAPWAP Base MIB (1/7)

For example:

Add some words to make the relationship with ENTITY-MIB more clear.

"By combining the MIBs, operators could query AC and WTP's status and properties. 

For example, they could get WTP's current status through CAPWAP-BASE-MIB,

and WTP's software revision information through ENTITY-MIB. "

3) Remove 6.1. Textual Conventions section as it is redundant with MIB definition

4) Updated the MIB definition

CAPWAP Base MIB (2/7)

• Change module name from CAPWAP-MIB to CAPWAP-BASE-MIB• Use capwapBase as prefix for all MIB objects and TC.• For TCs, they are changed with "TC" characters as suffix.• Add  DISPLAY-HINT for TCs such as CapwapBaseWtpIdTC .• As per latest protocol draft, update the reference part, DESCRIPTION part, value scope and so on for MIB objects required to modify• To improve readability of MIB object name, we replace "WTP" with "Wtp","AC"with "Ac"..... For example, we rename  "capwapWTPState"   as "capwapBaseWtpState"

CAPWAP Base MIB (3/7)

• We used to use capwapWTPACNameList to provide AC name list info. Now, we use capwapBaseAcNameListTable to replace it and it is able to support more AC name items.• Fix some syntax error, for example, capwapBaseStationVlanName should use SnmpAdminString type.• All notification objects use capwapBaseNtf as prefix.

Changes between 01 and 02The main work is to close one open issue:• Update access right for MIB object, especially writable

objects

CAPWAP Base MIB (4/7)

Also, made the Alignment format consistent in the definition section

1) Make capwapBaseAcNameListTable support create, modify and delete operation.

2) Add capwapBaseMacAclTable table to support station ACL configuration function.

3) Add new objects to support functions such as control

Channel’s security policy configuration.

Changes between 02 and 03The main work is to close one open issue:• To able to manage CAPWAP protocol’s timer and variables

To manage CAPWAP protocol’s timer and variables1) Add MIB objects for timer and variables in the

capwapBaseParameters group and capwapBaseWtpTable. For example, we define capwapBaseAcEchoInterval object

for echo request interval variable.2) To retrieve WTP's CAPWAP protocol timers and variables

information, the following capwap message element extensions are defined using VendorSpecific Payload message element.

CAPWAP Base MIB (5/7)

CAPWAP Base MIB (6/7)

CAPWAP Protocol Timers CAPWAP Protocol Variables

The extensions will be carried by Configuration Status Response Message or Configuration Update Response Message

Besides above changes, we update Section 11 for capwapBaseParameters group, capwapBaseAc group and capwapBaseMacAclTable to describe the security considerations for them .

Also, we added an appendix section to log changes between versions.

CAPWAP Base MIB (7/7)

Current Work Status CAPWAP Base MIB CAPWAP Dot11 Binding MIB Open Issue Next Step

Agenda

Changes between 00 and 01

The main work is to make MIB model consistent

with dot11 binding protocol and improve draft’s readability.

1) Close all review comments from Dan.

2) To improve readability, we updated the section 5 Overview,

7. Relationship to Other MIB Modules,

8. Example of CAPWAP-DOT11-MIB Usage

3) To make it more clear, we replace “IEEE 802.11 MIBs”

with “MIBs defined in IEEE 802.11 standard and

its amendments”

CAPWAP Dot11 Binding MIB (1/4)

4) Remove 6.1. Textual Conventions section as it is redundant with MIB definition

4) Emphasize the reuse scope of Dot11 binding MIB

In the 7.4. Relationship to the MIBs defined in IEEE

802.11 standard and it samendments, we added:In the 802.11 binding document [I-D.ietf-capwap-protocol-binding-ieee80211],

it involves a part of MIB objects defined by IEEE 802.11standard and

its amendments. Although CAPWAP-DOT11-MIB uses the 802.11 binding

document as a reference, it could reuse all the MIB objects

defined by IEEE 802.11 standard and its amendments , and

Not limited by the scope of the 802.11 binding document.

CAPWAP Dot11 Binding MIB (2/4)

5) Clarify the function of 'WLAN Service Interface' and

'WLAN BSS Interface' in the section 7.2. Relationship to the

IF-MIB and section 8. Example of CAPWAP-DOT11-MIB Usage

6) Updated the MIB definition

CAPWAP Dot11 Binding MIB (3/4)

• For TCs, they are changed and use "TC" characters as suffix.• Add  DISPLAY-HINT for CapwapDot11WlanIdTC TCs • As per latest protocol draft, update the reference part, DESCRIPTION part, value scope and so on for MIB objects required to modify• Ensure all MIB objects and TC use capwapDot11 as prefix.• To improve readability of MIB object name, we replace "WTP" with "Wtp",“WLAN"with “Wlan"..... For example, we rename  "capwapWTPMACType "   as "capwapDot11WtpMacType "

Changes between 02 and 01

CAPWAP Dot11 Binding MIB (4/4)
