Cisco Systems 3560 Manual De Usuario

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 gigabitethernet0/1 rx

Switch(config)# monitor session 2 destination interface gigabitethernet0/2 encapsulation 

Switch(config)# end

monitor session session_number 
destination {interface interface-id [, | -] 
[encapsulation replicate] [ingress {dot1q 
vlan vlan-id | isl | untagged vlan vlan-id | 
vlan vlan-id}]}

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 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.

isl—Forward ingress packets with ISL encapsulation.

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.
