Configuring SPAN and RSPAN

Creating a Local SPAN Session and Configuring Incoming Traffic

Command or Action

Example:

Switch(config)# monitor session 1 destination interface gigabitethernet1/0/2 encapsulation replicate

Purpose

•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) [, -] Specifies a series or range of interfaces. Enter a space before and after the comma; enter a space before and after the hyphen.

(Optional) encapsulation replicate specifies that the destination interface replicates the source interface encapsulation method. If not selected, the default is to send packets in native form (untagged).

Note You can use monitor session session_number destination command multiple times to configure multiple destination ports.

Step 5 end Returns to privileged EXEC mode.

Example:

Switch(config)# end

Creating a Local SPAN Session and Configuring Incoming Traffic

Beginning in privileged EXEC mode, follow these steps to create a SPAN session, to specify the source ports or VLANs and the destination ports, and to enable incoming traffic on the destination port for a network security device (such as a Cisco IDS Sensor Appliance).

SUMMARY STEPS

1.configure terminal

2.no monitor session {session_number all local remote}

3.monitor session session_number source {interface interface-id vlan vlan-id} [, -] [both rx tx]

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