Description (partial)

Symptom: 1. IPDT  gets enabled on all bundle ports including RSL port due to which FEX does not come up after a reload, link flap, or SSO. FEX RSL channel members will be in ?u? state, that is unsuitable for a part of the etherchannel.

2. IPDT also gets enabled on the Service module (FWSM) internal port-channel and there is no way to recover them other than removing NMSP (as internal port-channels are non-configurable and non-accessible).
Conditions: This symptom occurs after a reload with "NMSP" protocol.
