Local suspended VLANs is suspended on the 2 N5 of the vPC.

Update(s):

Date: 2011-03-28 09:40:03 UTC
workaround is to activate and deactivate immediately
the spantree on the vlan that poses the problem:

pcc-15b-n5(config-sys-qos)# sh vpc consistency-parameters global | i \"Local suspended\"
Local suspended VLANs - 1100-1149,2100-2149 -
pcc-15b-n5(config-sys-qos)# spann vlan 1100-1149,2100-2149
pcc-15b-n5(config)# no spann vlan 1100-1149,2100-2149
pcc-15b-n5(config)# sh vpc consistency-parameters global | i \"Local suspended\"
Local suspended VLANs - - -



Date: 2011-03-23 15:16:29 UTC
# sh vpc consistency-parameters global
Local suspended VLANs - - -

it was fixed.

Date: 2011-03-23 15:16:03 UTC
reboot of the peer

# sh inter vlan 2400
