Removing Ports from a SPAN Session
Beginning in privileged EXEC mode, follow these steps to remove a port as a SPAN source for a session:
Command
Step 1
configure terminal
Step 2
no monitor session session_number source
interface interface-id [, | -] [both | rx | tx]
Step 3
end
Step 4
show monitor [session session_number]
Step 5
copy running-config startup-config
To remove a source or destination port from the SPAN session, use the no monitor session
session_number source interface interface-id global configuration command or the no monitor session
session_number destination interface interface-id global configuration command. To change the
encapsulation type back to the default (native), use the monitor session session_number destination
interface interface-id without the encapsulation keyword.
This example shows how to remove a port as a SPAN source for SPAN session 1:
Switch(config)# no monitor session 1 source interface fastethernet0/1
Switch(config)# end
This example shows how to disable received traffic monitoring on a port that 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.

Purpose
Enter global configuration mode.
Specify the characteristics of the source port (monitored port) and
SPAN session to remove.
For session, specify 1.
For interface-id, specify the source port to no longer monitor. Valid
interfaces include physical interfaces and port-channel logical
interfaces (port-channel port-channel-number).
(Optional) Use [, | -] to specify a series or range of interfaces if they
were configured. This option is valid when monitoring only
received traffic. Enter a space before and after the comma; enter a
space before and after the hyphen.
(Optional) Specify the direction of traffic (both, rx, or tx) to no
longer monitor. If you do not specify a traffic direction, both
transmit and receive are disabled.
Return to privileged EXEC mode.
Verify your entries.
(Optional) Save your entries in the configuration file.
