Chapter 10 Configuring the Switch Ports
Configuring SPAN
Both: Gi0/1
Destination Ports: Gi0/2
Use the show monitor session privileged EXEC command to verify the configuration.
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:
To remove a destination port from the SPAN session, use the no monitor session session_number
destination interface interface-id global configuration command.

Source Ports:
RX Only: None
TX Only: None
Both: None
Destination Ports:Gi0/2
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 gigabitethernet0/1 rx
Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2
no monitor session session_number source
interface interface-id [, | -][both | rx | tx]
Specify the characteristics of the source port (monitored port) and
SPAN session to remove.
For session,specify1.
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,ortx)tono
longer monitor. If you do not specify a traffic direction, both
transmit and receive are disabled.
Step 3
end Return to privileged EXEC mode.
Step 4
show monitor [session session_number] Verify your entries.
Step 5
copy running-config startup-config (Optional) Save your entries in the configuration file.
