Chapter 1 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 or destination port or VLAN from the SPAN session, use the no monitor session
session_number source { interface interface-id | vlan vlan-id } global configuration command or the no
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 gigabitethernet1/0/1 rx
Switch(config)#
monitor session 2 destination interface gigabitethernet1/0/2 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:
Step 5
end Return to privileged EXEC mode.
Step 6
show monitor [ session session_number ]
show running-config
Verify the configuration.
Step 7 copy running-config startup-config (Optional) Save the configuration in the configuration file.
Command Purpose
Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2 no monitor session { session_number | all |
local | remote }
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.
Step 3 monitor session session_number source
interface 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 monitor session session_number filter vlan
vlan-id [ , | - ]
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.
