Configuring RSPAN
Removing Ports from an RSPAN Session
To remove a port as an RSPAN source for a session, perform this task:
This example shows how to remove port 1 as an RSPAN source for RSPAN session 1:
Switch(config)# no monitor session 1 source interface gigabitEthernet1/1
Switch(config)# end
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 gigabitEthernet1/1 rx
The monitoring of traffic received on port1 is disabled, but traffic transmitted from this port continues
to be monitored.
Command Purpose
Step1 Switch# configure terminal Enters global configuration mode.
Step2 Switch(config)# [no] monitor session
{
session_number
} {source {interface
interface_list
| {vlan
vlan_IDs
| cpu
[queue
queue_ids
]} [rx | tx | both]
Specifies the characteristics of the RSPAN source port (monitored
port) to remove.
For session_number, specifies the session number identified with
this RSPAN session (1 through 6).
For interface-list, specifies the source port to no longer monitor.
Valid interfaces include physical interfaces and port-channel
logical interfaces (port-channel port-channel-number).
For vlan_IDs, specifies the source vlan or vlans to monitor. Valid
VLANs are in the range from 1 to 4094.
For queue_ids, specifies either a set of CPU queue numerical
identifiers from 1 to 32, or a named queue.
(Optional) [, | -] Specifies a series or range of interfaces. Enter a
space after the comma; enter a space before and aft er the hyphen.
(Optional) Specifies the direction of traffic to monitor. If you do
not specify a traffic direction, the source interface sends both
transmitted (Tx) and received (Rx) traffic. Only received traffic can
be monitored on additional source ports.
Rx—Monitor received traffic.
Tx—Monitor transmitted traffic.
both—Monitor both received and transmitted traffic
(bidirectional).
Step3 Switch(config)# end Returns to privileged EXEC mode.
Step4 Switch# show monitor [session
session_number
]
Verifies your entries.
Step5 Switch# copy running-config
startup-config
(Optional) Saves your entries in the configuration file.
