L2 Verification & Troubleshooting  

The following commands are helpful for verifying and troubleshooting ethernet switching and VLANs:

user@host> show ethernet-switching mac-learning-log        
(Technical documentation reference:   show ethernet-switching mac-learning-log)

user@host> show ethernet-switching table            
(Technical documentation reference:   show ethernet-switching table)

user@host> show vlans
user@host> show vlans <vlan> extensive

user@host> show ethernet-switching table interface <interface>

user@host> monitor interface <vlan interface>

show interfaces vlan                   /to see the vlan in SRX
show system users                      /to see the user in Mx480

monitor interface traffic
====================================================================
user@host> monitor interface traffic
>monitor interface so-1/0/0.0

====================================================================
show route resolution unresolved

user@host> show route resolution unresolved
