cbQosPolicyIndex

Hi

I'm currently in the process of collecting information for our COS3/COS4 monitoring.

According to Cisco documentation the cbQosPolicyIndex is important to find the informations in the various SNMP-OID tables.

Now the SNMP documentation for cbQosPolicyIndex on the other hand says this information is not accessible.

So catch-22, anyone has a workaround for that?

Re: cbQosPolicyIndex

The above object you mention is not accessible, but you can use different objects listed below to get this info.

Here is a step by step procedure for using the CBQOS MIB. Each router would have a different indexing scheme and so it is necessary for you to understand the info given below and "modify" this to meet your rtr's idex values

1) Query your ifDescr to find the interaface index that has the policy

OV_BIN/snmpwalk -c public 14.32.100.75 ifDescr

interfaces.ifTable.ifEntry.ifDescr.1 : DISPLAY STRING- (ascii): FastEthernet0/0

2) Query the cbQosIfIndex to get the QOS mapping to Index

OV_BIN/snmpwalk -c public 14.32.100.75 cbQosIfIndex

cbQosIfIndex.1111 : INTEGER: 1

cbQosIfIndex 1111 is the index for ifDescr 1 FastEthernet 0/0

3) Now query the cbQosClassMapCfg table for the cbQosCMName name object

nms:/opt/OV/bin # $OV_BIN/snmpwalk -c public 14.32.100.75 .1.3.6.1.4.1.9.9.166.1.7.1

cbQosCMName.1025 : DISPLAY STRING- (ascii): class-default

cbQosCMName.1097 : DISPLAY STRING- (ascii): Snmp

cbQosCMDesc.1025 : DISPLAY STRING- (ascii):

cbQosCMDesc.1097 : DISPLAY STRING- (ascii):

cbQosCMInfo.1025 : INTEGER: matchAny

cbQosCMInfo.1097 : INTEGER: matchAll

Once this is know we can query the cbQosConfigIndex to correlate the cbQosCMName value to our

cbQosIfIndex and cbQosConfigIndex

nms:/opt/OV/bin # $OV_BIN/snmpwalk -c public 14.32.100.75 .1.3.6.1.4.1.9.9.166.1.5.1.2

cbQosConfigIndex.1111.1111 : Unsigned32: 1107

cbQosConfigIndex.1111.1113 : Unsigned32: 1097

cbQosConfigIndex.1111.1117 : Unsigned32: 1105

cbQosConfigIndex.1111.1119 : Unsigned32: 1109

cbQosConfigIndex.1111.1121 : Unsigned32: 1025

cbQosConfigIndex.1111.1125 : Unsigned32: 1029

You take the values from cbQosConfigIndex and match them to values found in cbQosCMName for the

given Class-map name and this gives you the cbQosPolicyIndex, cbQosObjectsIndex values you need to

query the cbQosCMStatsTable table with for a given class-map

4) Next I know that the Index for cbQosCMStatsTable is numbers for (cbQosPolicyIndex,

cbQosObjectsIndex) 1111.1121 and 1111.1113.

Here I simply grep for 1113 and 1121 in my snmpwalk of the cbQosCMStatsTable to get the stats

values.
