Configuring an FSPAN Session

 

Command or Action

Purpose

 

 

(Optional) [, -] Specifies a series or range of interfaces. Enter a space

 

 

before and after the comma; enter a space before and after the hyphen.

 

 

Enter ingress with additional keywords to enable forwarding of incoming

 

 

traffic on the destination port and to specify the encapsulation type:

 

 

dot1q vlan vlan-idForwards incoming packets with IEEE 802.1Q

 

 

encapsulation with the specified VLAN as the default VLAN.

 

 

islForwards ingress packets with ISL encapsulation.

 

 

untagged vlan vlan-idor vlan vlan-idForwards incoming

 

 

packets with untagged encapsulation type with the specified VLAN

 

 

as the default VLAN.

Step 5

end

Returns to privileged EXEC mode.

 

Example:

 

 

Switch(config)# end

 

Configuring an FSPAN Session

Beginning in privileged EXEC mode, follow these steps to create a SPAN session, specify the source (monitored) ports or VLANs and the destination (monitoring) ports, and configure FSPAN for the session.
