Creating An Rspan Destination Session - Cisco Catalyst 3750-X Software Configuration Manual

Chapter 32 Configuring SPAN and RSPAN
Command
Step 5
monitor session session_number
destination remote vlan vlan-id
Step 6
end
show monitor [session session_number]
Step 7
show running-config
Step 8 copy running-config startup-config
To monitor all VLANs on the trunk port, use the no monitor session session_number filter vlan global
configuration command.
This example shows how to remove any existing configuration on RSPAN session 2, configure RSPAN
session 2 to monitor traffic received on trunk port 2, and send traffic for only VLANs 1 through 5 and 9
to destination RSPAN VLAN 902.
Switch(config)# no monitor session 2
Switch(config)# monitor session 2 source interface gigabitethernet0/2 rx
Switch(config)# monitor session 2 filter vlan 1 - 5 , 9
Switch(config)# monitor session 2 destination remote vlan 902
Switch(config)# end

Creating an RSPAN Destination Session

You configure the RSPAN destination session on a different switch or switch stack; that is, not the switch
or switch stack on which the source session was configured.
Beginning in privileged EXEC mode, follow these steps to define the RSPAN VLAN on that switch, to
create an RSPAN destination session, and to specify the source RSPAN VLAN and the destination port:
Command
Step 1 configure terminal
Step 2 vlan vlan-id
Step 3 remote-span
Step 4 exit
no monitor session {session_number | all |
Step 5
local | remote}
OL-21521-01
Purpose
Specify the RSPAN session and the destination remote VLAN
(RSPAN VLAN).
For session_number, enter the session number specified in Step 3.
For vlan-id, specify the RSPAN VLAN to carry the monitored traffic
to the destination port.rt group {a | b | c} to specify the ports that
carry RSPAN traffic.
Return to privileged EXEC mode.
Verify the configuration.
(Optional) Save the configuration in the configuration file.
Purpose
Enter global configuration mode.
Enter the VLAN ID of the RSPAN VLAN created from the source
switch, and enter VLAN configuration mode.
If both switches are participating in VTP and the RSPAN VLAN ID
is from 2 to 1005, Steps 2 through 4 are not required because the
RSPAN VLAN ID is propagated through the VTP network.
Identify the VLAN as the RSPAN VLAN.
Return to 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.
