2.2(1d)A 2.2(2c)A

Description (partial)

Symptom:
When issuing the command:

show platform software fcoe_mgr info global 

**Above command is run when show tech_support logs are collected on UCSM.**

the FI is creating a core file for the fcoe_mgr porcess and resets with a "fcoe_mgr hap reset".

Conditions:
The problem is a non contiguous vlan range allowed on the physical ethernet trunks on the UCS FIs.

If this list of vlans:

show interface ethernet x/y or port-channel x trunk

is too big we can see the problem described here. The number of entries in above list must be similar to this example from the cisco test lab:
