Configuring SPAN and RSPAN
This example shows how to configure VLAN 901 as the source remote VLAN and port 1 as the
destination interface:
Switch(config)#
monitor session 1 source remote vlan 901
Switch(config)#
monitor session 1 destination interface gigabitethernet0/1
Switch(config)#
end
Creating an RSPAN Destination Session and Configuring Incoming Traffic
Beginning in privileged EXEC mode, follow these steps to create an RSPAN destination session, to
specify the source RSPAN VLAN and the destination port, and to enable incoming traffic on the
destination port for a network security device (such as a Cisco IDS Sensor Appliance).
For details about the keywords not related to incoming traffic, see the
“Creating an RSPAN Destination
Session” section on page 27-19
. This procedure assumes that the RSPAN VLAN has already
been configured.
