VLAN Based Traffic Shaping Cisco Switch

by

VLAN Based Traffic Shaping:

Today i will discuss how to configure VLAN based traffic shaping on cisco Catalyst ME3400 switch. Suppose you have 4 vlan [21,22,23,24] on a trunk port & you want to bandwidth shaping specific vlan 21 & 22. Here we declare 5Mbps BW for Vlan 21 & 2Mbps BW for Vlan 22. [boxads]

You can enable bandwidth shaping on an interface (or sub-interface) in three easy steps. Just remember: class, policy & interface.

Class:

At first you need to create a class map for those Vlan. Here we create vlan21 & vlan22 as a class map.

class-map match-all vlan21
 match vlan  21
class-map match-all vlan22
 match vlan  22

policy:

Now it’s time to define our policy map. In this case, we’re going to take any traffic that matched the vlan21 & vlan22 class (which, as you remember, is all traffic) and apply a shaping policy to it. Also we create subvlan & mainvlan policy map.
