[j-nsp] ifAlias on sub-interfaces

[Serge Vautour]

Hello,

I'm not seeing sub-interface descriptions show up in ifAlias. Has anyone seen 
this before?


MYBOX-re0> show  interfaces ge-5/0/1  
extensive                                                               

Physical interface: ge-5/0/1, Enabled, Physical link is Up
  Interface  index: 210, SNMP ifIndex: 507, Generation: 257
  Description:  [BLAH1][BLAH2][BLAH3]
 
If I walk ifAlias  for this SNMP ID:
 
[me at vmrancid-ngn-nb00s0 ~]$ snmpwalk -v 2c -c string 10.10.10.10 
.1.3.6.1.2.1.31.1.1.1.18.507
IF-MIB::ifAlias.507 = STRING: [BLAH1][BLAH2][BLAH3]
 
Now a  sub-interface:
 
MYBOX-re0> show  interfaces ge-5/0/1.2 extensive  
  Logical interface ge-5/0/1.2 (Index 123)  (SNMP ifIndex 646) (Generation 412)
    Description:  [Sub1][Sub2][Sub3]
 
If I walk it's  ifIndex:
 
[me at vmrancid-ngn-nb00s0 ~]$ snmpwalk -v 2c -c string 10.10.10.10 
.1.3.6.1.2.1.31.1.1.1.18.646
IF-MIB::ifAlias.646 = STRING: 

Is this a bug in Junos? Is there some other MIB Juniper stores this in?

Thanks,
Serge
