Cisco ASR 9000 SNMP MIB support for double tagging

[rpendurty]

Hi, I need to pull the service inventory using SNMP and I am looking for the respective MIB which provides information about VLAN double tagging configured on a subinterface. I need to know the inner VLAN and outer VLAN information from the MIB. The equivalent CLI command is -

encapsulation dot1q 2002 second-dot1q 1110 configured under a subinterface on Cisco ASR 9000 device.

Any help on this will be highly appreciated. Thanks

Regards,

Ravi

All MIBs and OIDs that we support on asr90000 are documented on these two locations:

Hi Aleksandar,

I already browsed them before posting the question. I could not find any details related to support for double tagging in SNMP MIBs of ASR9K. Am I missing something here or is there no support in Cisco SNMP implementation?

Thanks

I don't think there is an OID for this type of data. Have you found an IEEE MIB where this is included?

I did not see an IEEE MIB but there is a Cisco proprietary MIB - CISCO-QINQ-VLAN-MIB which matches exactly with what I am looking for. However from the supported MIB list for ASR9K devices, the above MIB is missing. Looks like alternatives to SNMP have to be explored to get this information. Surprisingly, Huawei has implemented a similar proprietary MIB in its routers.
