Hi there,


Yes you can do this, but you would do it in QoS. In the class-map you would match on either the vlan or the IP address and then in the policy-map, you would shape to 250k on the egress ports on the box


That would sort it.

Thank You for a response,


I have a 3550(VTP mode Server) where all VLANs are established, and other 2950(VTP Mode Client) are connected with this 3550 Switch, If i developed a policy of 250Kbps on a 3550 accross a VLAN will it start to work ?

Hey there,


Yes it will - providing you've got the layer 3 functionality. In the class map, match on either the vlan or ref. an access list and grab the network range. The other vlans/networks will not be referenced and will take as much bandwidth as they can (as per normal)
