Hi everyone,
Could someone help me with the problem below? I wanted to add new VLANs 60 & 61 but they are suspended/disallowed over the Peer Link or the Trunk, Does anyone of you have experience in this issue please help?

Hi there,
Vlans 60-61 are suspended because they are only allowed on the peer-link end of the local switch, but they weren't allowed on the peer switch also - so they're suspended due to vPC config inconsistency. Take another look at the "show vpc consistency-parameters global" output you have provided and you will notice that:
Allowed VLANs
Local Value:
10-13,20,24,60-61,70,80,156,211,278,280-286,901-903,3000
Peer Value:
10-13,20,24,70,80,156, 211,278,280-286,901-903,3000
After fixing the allowed vlans mismatch, you'll see them removed from the suspended vlans list; if you don't - pls share the vPC related running config.
Cheers!
