[e-nsp] x650 and port mirroring

[Marcin Kuczera]

hello,

on the Alpine switch I could create a sharing group i.e. of 4 ports, and 
then this group could be used as a mirror port.

In x650 I can't do that, XOS refuses enabling sharing master port as 
mirror port.

* Slot-1 SummitStack-GZE.27 # enable mirroring to port 1:21
Error: Port mirroring cannot be enabled on a trunk member port 1:21
Configuration failed on backup MSM, command execution aborted!

what is the problem ?
is it possible at all ?

Regards,
Marcin
