This example shows how to configure VLAN 901 as the source remote VLAN and port 5 as the
destination interface:
Switch# configure terminal
Enter configuration commands, one per line.
Switch(config)# monitor session 1 source remote vlan 901
Switch(config)# monitor session 1 destination interface gigabitEthernet1/2
Switch(config)# end

Creating an RSPAN Destination Session and Enabling Ingress Traffic

To create an RSPAN destination session, to specify the source RSPAN VLAN, and to enable ingress
traffic on the destination port for a network security device (such as a Cisco IDS [Intrusion Detection
System] sensor appliance), perform this task:
Command
Step 1
Switch# configure terminal
Step 2
Switch(config)# monitor session
{session_number} source vlan vlan_IDs
OL-25340-01
Purpose
Specifies the RSPAN session and the destination interface.
For session_number, specifies the session number identified with this
RSPAN session (1 through 6).
For interface, specifies the destination interface.
For vlan_IDs, specifies the ingress VLAN, if necessary.
(Optional) [, | -] Specifies a series or range of interfaces. Enter a
space after the comma; enter a space before and after the hyphen.
(Optional) Specifies the direction of traffic to monitor. If you do not
specify a traffic direction, the source interface sends both sent and
received traffic. Only received (rx) traffic can be monitored on
additional source ports.
dot1q—Use 802.1Q encapsulation.
•
Returns to privileged EXEC mode.
Verifies your entries.
(Optional) Saves your entries in the configuration file.
End with CNTL/Z.
Purpose
Enters global configuration mode.
Specifies the RSPAN session and the source RSPAN VLAN.
For session_number, specifies the session number identified with this
RSPAN session (1 through 6).
For vlan_IDs, specifies the source VLAN or VLANs to monitor.
Valid VLANs are in the range from 1 to 4094.
