Configuring SPAN and RSPAN
How to Configure SPAN and RSPAN
Creating an RSPAN Source Session
Command Purpose
1. configure terminal Enters global configuration mode.
2. no monitor session { session_number | all |
local | remote }
Removes any existing RSPAN configuration for the session.
session_number —The range is 1 to 68.
all —Removes all RSPAN sessions
local— Removes all local sessions
remote— Removes all remote SPAN sessions.
3. monitor session session_number source
{ interface interface-id | vlan vlan-id } [ , | - ]
[ both | rx | tx ]
Specifies the RSPAN session and the source port (monitored port).
session_number —The range is 1 to 68.
Enter a source port or source VLAN for the RSPAN session:

interface-id —Specifies 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 10.

vlan-id —Specifies the source VLAN to monitor. The range is 1 to
4096 (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) [ , | - ]—Specifies 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 —Monitors both received and sent traffic.

rx —Monitors received traffic.

tx —Monitors sent traffic.
4. monitor session session_number
destination remote vlan vlan-id
Specifies the RSPAN session and the destination RSPAN VLAN.
session_number —Enters the number defined in Step 3.
vlan-id —Specifies the source RSPAN VLAN to monitor.
5. end Returns to privileged EXEC mode.
6. show monitor [ session session_number ]
show running-config
Verifies the configuration.
7. copy running-config startup-config (Optional) Saves the configuration in the configuration file.
