Dear Community,
I have two nexus switches Switch A and Switch B running as VPC. I am working by Switch profile. I create and add the vlan on interface port channel 1 on Nexus 5000 Switch Profile. The new vlan created successfully and add on in port channel interface.
1) I can see the vlan is available on both switches Switch A and Switch B.
2) Vlan is add on the interface port channel.
3) By using sh int trunk, i can see the new vlan is successfully added.
Problem.
We i see the VPC link. VPC Link is showing only the earlier vlan. VPC not showing the new added vlan 100 as acive VPC vlan.

3) Error Logs:
SWA: %ETHPORT-3-IF_ERROR_VLANS_SUSPENDED: VLANs 100 on Interface port-channel1 are being suspende
d. (Reason: Vlan is not allowed on Peer-link)
Solution:
What can be the solution for this?
I found 1 Solution as following.
no spanning-tree vlan X
- spanning-tree vlan X
where X can be an unused vlan, not necessarily defined.
Can i know the following.
1) Is the Command Impact will be on local switch or on Whole network infrastructure?
2) Is this command will Disable/Enable the Spanning tree the all Vlan Instances?
