Hello Guys

I have a problem with a port mirroring session on a stack with 4 members Alcatel OS6900-X72 in version 8.5.196.R04 GA.
I try to setup the port mirroring with the following commands :

SWITCHNAME > port-mirroring 4 source port 1/1/1 destination linkagg 103
ERROR: Source port 1/1/1 invalid

Whereas if I try with the following commands it works :
SWITCHNAME > port-mirroring 4 source port 2/1/1 destination linkagg 103
SWITCHNAME > show port-mirroring status

Session Mirror Mirror Unblocked RPMIR Config Oper

4. 2/1/1 bidirectional – – Enable Off

I tried with a port which belongs to a link aggregation on another switch of the stack and it works fine.

The port mirroring does not work on the first member and the fourth member of the stack. On the two other members every port can be mirrored.

Do you have any idea related to this “source port invalid” ?

I will be pleased to give you any further information to help me troubleshoot this issue.
