For DELL Force 10 Series

1 . For a Force 10 switch, commands are different, here how to enable port mirroring. The following example shows how traffic on port 0/41 (source port) is copied to port 0/9 (destination port) :

dell (config)# monitor session 0
dell (conf-mon-sess-0)# source GigabitEthernet 0/41 destination GigabitEthernet 0/9 direction both
Note You may experiment the following error :
dell (conf-mon-sess-0)#source gigabitethernet 0/41 destination gigabitethernet 0/9 direction both
% Error: MG port is in L2 mode

Yes, port monitoring cannot be configured if port where the data will be mirrored is layer 2. You must remove the L2 configuration on the port before continuing.
