Verifying Integrated Routing and Bridging Interface Status and Statistics
Purpose
Determine status information and traffic statistics for integrated routing and bridging (IRB) interfaces.
Action
Display IRB interfaces and their current states:
user@switch> show interfaces irb terse Interface Admin Link Proto Local Remote irb up up irb.111 up up inet 111.111.111.1/24 ...
Display Layer 2 VLANs, including any tags assigned to the VLANs and the interfaces associated with the VLANs:
user@switch> show vlansRouting instance VLAN name Tag Interfaces
default-switch irb 101
default-switch support 111
ge-0/0/18.0
...
Display Ethernet switching table entries for the VLAN that is attached to the IRB interface:
user@switch> show ethernet-switching tableMAC flags (S -static MAC, D -dynamic MAC, L -locally learned
SE -Statistics enabled, NM -Non configured MAC, R -Remote PE MAC)
Routing instance : default-switch
Vlan MAC MAC Age Logical
Name address flags interface
support 00:01:02:03:04:05 S - ge-0/0/18.0
...
Display the ingress-counting statistics of an IRB interface with either the show interfaces irb detail command or the show interfaces irb extensive command. Ingress counting is displayed as Input bytes and Input packets and egress counting is displayed as Output bytes and Output packets under Transit Statistics.

Meaning
- show interfaces irb terse displays a list of interfaces, including IRB interfaces, and their current states (up, down).
- show vlans displays a list of VLANs, including any tags assigned to the VLANs and the interfaces associated with the VLANs.
- show ethernet-switching table displays the Ethernet switching table entries, including VLANs attached to the IRB interface.
- show interfaces irb detail displays IRB interface ingress counting as Input Bytes and Input Packets under Transit Statistics.
