Local suspended VLAN Recovery on Nexus 5k

Dear All.

Is there any workaround to recover suspended VLANs automatically? They get recovered only on the peer-link, but not on the rest of vPCs.

I need either to bounce the interface or remove/add vlan on the host vPC, which is not a best solution.

SNALSIB101(config)# no spanning-tree vlan  201

SNALSIB101(config)# 2013 Oct 15 08:03:15 SNALSIB101 %ETHPORT-3-IF_ERROR_VLANS_SUSPENDED: VLANs 201 on Interface port-channel1 are being suspended. (Reason: Global compat check failed)

2013 Oct 15 08:03:15 SNALSIB101 %ETHPORT-5-IF_TRUNK_DOWN: Interface port-channel1, vlan 201 down

2013 Oct 15 08:03:15 SNALSIB101 %ETHPORT-3-IF_ERROR_VLANS_SUSPENDED: VLANs 201 on Interface port-channel4001 are being suspended. (Reason: Global compat check failed)

2013 Oct 15 08:03:15 SNALSIB101 %ETHPORT-3-IF_ERROR_VLANS_SUSPENDED: VLANs 201 on Interface port-channel10 are being suspended. (Reason: Global compat check failed)

2013 Oct 15 08:03:15 SNALSIB101 %ETHPORT-3-IF_DOWN_INACTIVE: Interface port-channel4001 is down (Inactive)

2013 Oct 15 08:03:15 SNALSIB101 %ETHPORT-5-IF_TRUNK_DOWN: Interface port-channel10, vlan 201 down

Gets recovered only on the peer-link:

SNALSIB101(config)# spanning-tree vlan  201

SNALSIB101(config)# 2013 Oct 15 08:03:20 SNALSIB101 %ETHPORT-3-IF_ERROR_VLANS_REMOVED: VLANs 201 on Interface port-channel1 are removed from suspended state.

2013 Oct 15 08:03:20 SNALSIB101 %ETHPORT-5-IF_TRUNK_UP: Interface port-channel1, vlan 201 up

SNALSIB101(config)# sh int po4001

port-channel4001 is down (inactive)

Local suspended VLAN Recovery on Nexus 5k

Hello,

could you attach here the configuration?

Also, the following commands' output:

show vpc consistency-parameters global

show vpc consistency-parameters interface port-channel 4001

show vpc consistency-parameters interface port-channel 10

But, first of all try to shutdown/no shutdown the Port-Channel interfaces.

Best regards.

Local suspended VLAN Recovery on Nexus 5k

I see a consistency problem on vlan 201.

First of all, review your port-channel configuration on both peers. If all are right, try to do this:

Conf
Vlan 201
State active

Good luck!
