Removing Ports From A Span Session - Cisco WS-C3550-12G Software Configuration Manual

Configuring SPAN

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 destination port from the SPAN session, use 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 port 1 as a SPAN source for SPAN session 1 and verify the
configuration:
Switch(config)# no monitor session 1 source interface gigabitethernet0/1
Switch(config)# end
Switch# show monitor session 1

Purpose
Enter global configuration mode.
Specify the characteristics of the source port (monitored port) and
SPAN session to remove.
For session, specify 1 or 2.
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 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.
