Configuring SPAN and RSPAN
monitor session session_number destination interface interface-id global configuration command. For
destination interfaces, the encapsulation and ingress options are ignored with the no form of the
command.
This example shows how to remove any existing configuration on SPAN session 2, configure SPAN
session 2 to monitor received traffic on Gigabit Ethernet source port 1, and send it to destination Gigabit
Ethernet port 2 with the same egress encapsulation type as the source port, and to enable ingress
forwarding with IEEE 802.1Q encapsulation and VLAN 6 as the default ingress VLAN.
Switch(config)# no monitor session 2
Switch(config)# monitor session 2 source gigabitethernet1/1 rx
Switch(config)# monitor session 2 destination interface gigabitethernet1/2 encapsulation
replicate ingress dot1q vlan 6
Switch(config)# end
Specifying VLANs to Filter
Beginning in privileged EXEC mode, follow these steps to limit SPAN source traffic to specific VLANs:
Command
Step 1
configure terminal
Step 2
no monitor session {session_number | all |
local | remote}
Step 3
monitor session session_number source
interface interface-id
Step 4
monitor session session_number filter vlan
vlan-id [, | -]

Purpose
Enter global configuration mode.
Remove any existing SPAN configuration for the session.
For session_number, the range is 1 to 66.
Specify all to remove all SPAN sessions, local to remove all local
sessions, or remote to remove all remote SPAN sessions.
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.
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.
