What might cause the following error on 8700 packet wave device.
S1*> sub-port add sub-port ctl-lion-uni class-element 2 vlan-untagged-data
ERROR: Adding elements for sub port idx 16 Traffic Class Element Parent Classification Conflict
Resolved issue. If a parent port already has a sub-port with a class element of vlan-untagged-data that class element cannot be used again on another sub-port. Class elements must be unique on a parent port so that traffic engrossing can be definitively classified to one and only one sub-port on the parent port unless the traffic is broadcast/multi-cast in nature.

Fred, do you know what that document is called and where it can be found?
