configuration mode.
1. Open a monitor session and assign a session number
switch(config)# monitor session 1
2. Configure the source port and the destination port, with the rx parameter for received packets.
The destination port is always an external port.
switch(config-mon-sess-1)#source intengigabitethernet 0/1 destination
extengigabitethernet 0/18 direction rx
3. Optional: Use the description command to add a label to the monitor session.
switch(config-mon-sess-1)#description Hello World!
