Creating and Deleting a SPAN Session
You create a SPAN session by assigning a session number using the monitor command. If the session
already exists, any additional configuration is added to that session.
To create a SPAN session, perform this task:
Command
Step 1
switch# configure terminal
Step 2
switch(config)# monitor session
session-number
The following example shows creating a SPAN session:
switch# configure terminal
switch(config)# monitor session 2
To ensure that you are working with a completely new session, you can delete the desired session number
or all SPAN sessions.
To delete SPAN sessions, perform this task:
Command
switch(config)# no monitor session {all
| session-number}
Configuring the Destination Port
The SPAN destination port can only be a physical port on the switch. There are minor differences
