Chapter 20 Configuring SPAN
Displaying SPAN Status
This example shows how to disable received traffic monitoring on port 1, which was configured for
bidirectional monitoring:
Switch(config)# no monitor session 1 source interface fastEthernet0/1 rx
The monitoring of traffic received on port 1 is disabled, but traffic sent from this port continues to be
monitored.
Displaying SPAN Status
To display the status of the current SPAN configuration, use the show monitor privileged EXEC
command.
This is an example of output for the show monitor privileged EXEC command for SPAN source
session 1:
Switch# show monitor session 1
