Command
Step 5
monitor session session_number
destination {interface interface-id [, | -]
[encapsulation replicate]}
Step 6
end
Step 7 show monitor [session session_number]
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 global
configuration command.
This example shows how to remove any existing configuration on SPAN session 2, configure SPAN
session 2 to monitor traffic received on Gigabit Ethernet trunk port 2, and send traffic for only VLANs
1 through 5 and VLAN 9 to destination Gigabit Ethernet port 1.
Switch(config)# no monitor session 2
Switch(config)# monitor session 2 source interface gigabitethernet1/0/2 rx
Switch(config)# monitor session 2 filter vlan 1 - 5 , 9
Switch(config)# monitor session 2 destination interface gigabitethernet1/0/1
Switch(config)# end

Purpose
Specify the SPAN session and the destination port (monitoring port).
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; enter a space before and after the hyphen.
(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).
Return to privileged EXEC mode.
Verify the configuration.
(Optional) Save the configuration in the configuration file.
