VE stays up although the VLAN is inactive

[rgrueebler]

Hi everyone,

I have a problem with an VE interface. It says up although the VLAN is inactive. Here is the status of the VLAN:

GLB1-EF1-RB1# sh vlan 266
VLAN             Name            State                      Ports           Classification
(F)-FCoE                                                    (u)-Untagged
(R)-RSPAN                                                   (c)-Converged
(T)-TRANSPARENT                                             (t)-Tagged
================ =============== ========================== =============== ====================
266              TRANSITVLAN_4N* ACTIVE                     Te 1/0/28(t)   

GLB1-EF1-RB1# sh vlan 266
VLAN Name State Ports Classification
(F)-FCoE (u)-Untagged
(R)-RSPAN (c)-Converged
(T)-TRANSPARENT (t)-Tagged
================ =============== ========================== =============== ====================
266 TRANSITVLAN_4N* INACTIVE(member port down) Te 1/0/28(t)


The VE stays up:

GLB1-EF1-RB1# sh ip inter br rb 1
Ve 266 192.168.1.1 default-vrf up up

Expected behavior:
The VE should go to shut down when the VLAN is not active.

Is is possible to force the VE to go down when the VLAN is INACTIVE?

Best regards
Remo

Hi,

Which NOS version are you using? 

I’m able to see the VE going to shutdown right when I remove the vlan from the only port (TE 2/0/2) which has vlan 400 configured.
