Configuring SPAN and RSPAN
Creating an RSPAN Source Session
Beginning in privileged EXEC mode, follow these steps to start an RSPAN source session and to specify
the monitored source and the destination RSPAN VLAN:
Command
Step 1
configure terminal
Step 2
no monitor session {session_number | all |
local | remote}
Step 3
monitor session session_number source
{interface interface-id | vlan vlan-id} [, | -]
[both | rx | tx]
Step 4
monitor session session_number
destination remote vlan vlan-id
Step 5
end
Step 6
show monitor [session session_number]
show running-config
Step 7
copy running-config startup-config
To delete a SPAN session, use the no monitor session session_number global configuration command.
OL-19720-02
Purpose
Enter global configuration mode.
Remove any existing RSPAN configuration for the session.
For session_number, the range is 1 to 66.
Specify all to remove all RSPAN sessions, local to remove all local
sessions, or remote to remove all remote SPAN sessions.
Specify the RSPAN session and the source port (monitored port).
For session_number, the range is 1 to 66.
Enter a source port or source VLAN for the RSPAN session:
For interface-id, specify the source port to monitor. Valid
•
interfaces include physical interfaces and port-channel logical
interfaces (port-channel port-channel-number). Valid
port-channel numbers are 1 to 6.
For vlan-id, specify the source VLAN to monitor. The range is 1
•
to 4094 (excluding the RSPAN VLAN).
A single session can include multiple sources (ports or VLANs),
defined in a series of commands, but you cannot combine source
ports and source VLANs in one session.
(Optional) [, | -] Specify a series or range of interfaces. Enter a space
before and after the comma; enter a space before and after the
hyphen.
(Optional) Specify the direction of traffic to monitor. If you do not
specify a traffic direction, the source interface sends both sent and
received traffic.
both—Monitor both received and sent traffic.
•
rx—Monitor received traffic.
•
tx—Monitor sent traffic.
•
Specify the RSPAN session and the destination RSPAN VLAN.
For session_number, enter the number defined in Step 3.
For vlan-id, specify the source RSPAN VLAN to monitor.
Return to privileged EXEC mode.
Verify the configuration.
(Optional) Save the configuration in the configuration file.
