I am trying to connect a Cat3560G switch to an N7K pair via a vPC. The VLANs I wish to trunk are being suspended, I am getting the following error messages:
2010 Jun 22 17:03:36 N7K-Core1 %ETHPORT-3-IF_ERROR_VLANS_SUSPENDED: VLANs 2,301 on Interface port-channel2 are being suspended. (Reason: Vlan is not allowed on Peer-link)

HA! 6 years ago. I'll post my feedback anyway since my solution doesn't seem to be here and I keep running into this problem.
I did...
vlan blah
shut
!then
!
vlan blah
no shut
Badabing! Looks like vpc or something needed a little refresh and that was enough to get the switch to check again.

I ran into same exact problem... Everything on the interface needs to match exactly to the other interfaces. I was missing the below from the edge switch side.
interface TenGigabitThernet1/0/1
description vpc 1015
switchport trunk native vlan xx
switchport trunk allowed vlan x,x,x,x
switchport mode trunk
switchport nonegotiate
spanning-tree link-type point-to-point
channel-group 1 mode active
interface TenGigabitThernet1/0/2
description vpc 1015
switchport trunk native vlan xx
switchport trunk allowed vlan x,x,x,x
switchport mode trunk
switchport nonegotiate
spanning-tree link-type point-to-point
channel-group 1 mode active
ip dhcp snooping trust <<<<<<< This is what I was missing on the te1/0/1 interface which caused it
to go into "suspended" Once I added it came right up.

I know the original post was for years ago.
Just to share. I had the same issue today. The mistake was that I did not define the desired VLAN on both vPC peers and got the same errors. So do not forget to define the VLAN on both vPC switches.
I wish I helped.
