Hi,
I seem to be having an issue when adding VLANs to our core 4500-x stack and attached 3850 stack. Whenever I add I see these messages on the 4500's. In this case we added VLAN112 to the 4500 and then added it to the 3850
%SPANTREE-2-RECV_PVID_ERR: Received BPDU with inconsistent peer vlan id 112 on Port-channel2 VLAN1.
%SPANTREE-2-BLOCK_PVID_PEER: Blocking Port-channel2 on VLAN0112. Inconsistent peer vlan.
%SPANTREE-2-BLOCK_PVID_LOCAL: Blocking Port-channel2 on VLAN0001. Inconsistent local vlan.
%SPANTREE-2-UNBLOCK_CONSIST_PORT: Unblocking Port-channel2 on VLAN0112. Port consistency restored.
%SPANTREE-2-UNBLOCK_CONSIST_PORT: Unblocking Port-channel2 on VLAN0001. Port consistency restored.
The 4500 config looks like this:
interface Port-channel2
description 3850a Uplink
switchport
switchport mode trunk
interface TenGigabitEthernet1/1/4
description 3850a Uplink
switchport mode trunk
channel-group 2 mode on
!
interface TenGigabitEthernet2/1/4
description 3850a Uplink
switchport mode trunk
channel-group 2 mode on

The 3850's Config:
interface Port-channel1
description 4500 Uplink (Po1)
switchport mode trunk
interface TenGigabitEthernet1/1/3
description 4500 Uplink
switchport mode trunk
auto qos trust
channel-group 1 mode on
service-policy input AutoQos-4.0-Trust-Cos-Input-Policy
service-policy output AutoQos-4.0-Output-Policy
