Configuring SPAN and RSPAN
Command
Step 4
monitor session session_number
destination {interface interface-id [, | -]
[encapsulation {dot1q | replicate}] [ingress
{dot1q vlan vlan-id | untagged vlan vlan-id
| vlan vlan-id}]}
Step 5
end
Step 6
show monitor [session session_number]
show running-config
Step 7
copy running-config startup-config
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 gigabitethernet1/1 rx
Switch(config)# monitor session 2 destination interface gigabitethernet1/2 encapsulation
replicate ingress dot1q vlan 6
Switch(config)# end

Purpose
Specify the SPAN session, the destination port, the packet
encapsulation, and the ingress VLAN and encapsulation.
For session_number, specify the session number entered in Step 3.
For interface-id, specify the destination port. The destination
interface must be a physical port; it cannot be an EtherChannel, and
it cannot be a VLAN.
(Optional) [, | -] Specify a series or range of interfaces. Enter a space
before and after the comma or hyphen.
(Optional) Enter encapsulation dot1q to specify that the destination
interface uses the IEEE 802.1Q encapsulation method.
(Optional) Enter encapsulation replicate to specify that the
destination interface replicates the source interface encapsulation
method. If not selected, the default is to send packets in native form
(untagged).
Enter ingress with keywords to enable forwarding of incoming
traffic on the destination port and to specify the encapsulation type:
dot1q vlan vlan-id—Accept incoming packets with IEEE
•
802.1Q encapsulation with the specified VLAN as the default
VLAN.
untagged vlan vlan-id or vlan vlan-id—Accept incoming
•
packets with untagged encapsulation type with the specified
VLAN as the default VLAN.
Return to privileged EXEC mode.
Verify the configuration.
(Optional) Save the configuration in the configuration file.
