Chapter 30 Configuring SPAN and RSPAN
Configuring SPAN and RSPAN
To delete a SPAN session, use the
no
monitor session
session_number
global configuration command.
To remove a source port or VLAN from the SPAN session, use the
no monitor session
session_number
source
{
interface
interface-id |
vlan
vlan-id
}
global configuration command. To remove the RSPAN
VLAN from the session, use the
no monitor session
session_number
destination remote vlan
vlan-id.
This example shows how to remove any existing RSPAN configuration for session 1, configure RSPAN
session 1 to monitor multiple source interfaces, and configure the destination as RSPAN VLAN 901.
Switch(config)#
no monitor session 1
Switch(config)#
monitor session 1 source interface gigabitethernet1/0/1 tx
Switch(config)#
monitor session 1 source interface gigabitethernet1/0/2 rx
Switch(config)#
monitor session 1 source interface port-channel 2
Switch(config)#
monitor session 1 destination remote vlan 901
Switch(config)#
end
Specifying VLANs to Filter
Beginning in privileged EXEC mode, follow these steps to configure the RSPAN source session to limit
RSPAN source traffic to specific VLANs:
Step 6

Remove any existing SPAN configuration for the session.
For
session_number
, the range is 1 to 66.
Specify

to remove all SPAN sessions,
local
to remove all local
sessions, or
remote
to remove all remote SPAN sessions.
Step 3
monitor session

interface-id
Specify the characteristics of the source port (monitored port) and
SPAN session.
For
session_number
, the range is 1 to 66.
For
interface-id
, specify the source port to monitor. The interface
specified must already be configured as a trunk port.
Step 4

Limit the SPAN source traffic to specific VLANs.
For
session_number
, enter the session number specified in step 3.
For
vlan-id
, the range is 1 to 4094.
(Optional) Use a comma (
,
) to specify a series of VLANs or use a
hyphen (
-
) to specify a range of VLANs. Enter a space before and after
the comma; enter a space before and after the hyphen.
