[c-nsp] Cisco ASR1004 running IOS 12.2(33)XNF2 does not return SNMP cbQosIfIndex

[Martin T]

Hi!

I have a Cisco ASR1004 running IOS 12.2(33)XNF2 on IOS XE 02.06.02,
which for some reason, does not return cbQosIfIndex for some
interfaces. For example, here is an interface with input
service-policy configuration applied:

asr1004#sh policy-map interface TenGigabitEthernet1/1/0.260 input
 TenGigabitEthernet1/1/0.260

  Service-policy input: CIR-100MB

    Class-map: class-default (match-any)
      199728955 packets, 26519919043 bytes
      30 second offered rate 1000 bps, drop rate 0000 bps
      Match: any
      police:
          cir 104857500 bps, bc 3276780 bytes
          pir 104857500 bps, be 3276796 bytes
        conformed 199728955 packets, 26519919043 bytes; actions:
          transmit
        exceeded 0 packets, 0 bytes; actions:
          drop
        violated 0 packets, 0 bytes; actions:
          drop
        conformed 1000 bps, exceed 0 bps, violate 0000 bps
asr1004#


Te1/1/0.260 is up and has traffic on both directions on it. IfIndex of
this interface is 155:

asr1004#sh snmp mib ifmib ifindex TenGigabitEthernet1/1/0.260
Interface = TenGigabitEthernet1/1/0.260, Ifindex = 155
asr1004#

I can also confirm this with SNMP:

$ snmpget -v 2c -c public asr1004 ifDescr.155
IF-MIB::ifDescr.155 = STRING: TenGigabitEthernet1/1/0.260
$


However, for some reason, SNMP agent does not return the interface
index despite the fact that ifIndex 155(Te1/1/0.260) has a policy
associated with it:

$ snmpwalk -v 2c -c public asr1004 cbQosIfIndex | grep 155
$

For some other interfaces, with identical configuration, the
cbQosIfIndex query returns the ifIndex.

Is this a bug? Has anyone seen this before?


thanks,
Martin
