Nexus 3000 - Vlan1 is suspended - protocol-down/link-down/admin-up

[kish02]

Hi, both my Nexus 3000 had an unexpected shutdown. When powered up Vlan 1 is suspended and only the management IP is pingable. Do you have any idea what might cause this and how to resolve this? Before the loss of power, everything is working.

On the same switch, interfaces that are member of port-channel also has suspnd status. Recreating the port-channel and reenrolling the interface back to the po works for some interfaces but some remain suspended. 

any help would be appreciated, thank you.

I think that the nsk suspended individual port member this with autostate enable make vlan1 down. 

For workaround shut/no shut PO in both side

For this case not occure again I will check one command.

the shut/no shut doesnt work

did you check the peer-link, are these VLAN (include VLAN1) is allow in peer-link 
I think to dont copy run start so NSK after power suspend the VLAN
