Description (partial)

On shutting down a FEX Fabric Port-Channel, we send linkDown and cieLinkDown SNMP traps. When the interface is brought back up, we send linkDown and cieLinkDown traps again, rather than the expected linkUp.

This has been seen on Nexus 7000s running 6.1.3 where the N2Ks are connected to F2 modules. It has been seen with 2232 and 2248 module FEXs.
