Hi all

Are IRB interfaces suppose to show up in SNMP walks? As you can see I got an ae0 and ae0.30, both have SNMP ifIndex and when I do snmp walk I can find it. But if I use the SNMP ifIndex for an irb interface, irb.45, I couldn't find it. 

{master}
> show interfaces ae0
Physical interface: ae0, Enabled, Physical link is Up
  Interface index: 128, SNMP ifIndex: 739
  Logical interface ae0.30 (Index 365) (SNMP ifIndex 742)
 
{master}
> show interfaces irb.45
  Logical interface irb.45 (Index 336) (SNMP ifIndex 756)
 

{master}
> show snmp mib walk 1 | match 739
dot3adAggMACAddress.739  ... bla bla 
dot3adAggPortListPorts.739 = ... bla bla

{master}
> show snmp mib walk 1 | match 742
dot3adAggMACAddress.742  ... bla bla
dot3adAggPortListPorts.742 =  ... bla bla
{master}
> show snmp mib walk 1 | match 756

 

Hi Folks,

I can poll data for irb interfaces as below, its my mx104 box running on 13.3R10.2. Please let me know your box/version,

Hi Folks,

To add there is no known restriction for fetching irb interface statistics with snmp to my knowledge.
