Known Affected Releases

6.2(7)S34

Description (partial)

Symptom:
ISSD from 6.2(7) to lower version on M9700 is allowed, despite the VLAN, Ethernet-port-chanel and VFC interface configurations being present. If any or all of these configuration(s) is present before the downgrade on a subsequent upgrade to 6.2(7) we may see issues involving either port-channel configurations failing, VFC bring-up or FCoE traffic getting affected.

Conditions:
On ISSD from 6.2(7) to a lower version on the M9700 platform the the Ethernet related configurations should all be removed by the user. For most of the configurations there is a config check provided to ensure this happens. This config check does not exist to three configurations 
(1) VLAN and VLAN to VSAN mapping
(2) Ethernet port-channels related configuration
(3) VFC interface related configuration
