Need to apply Qos to provide dedicated bandwidth.

[renzil]

Hi forum,

I have got a 1 Mbps leased line ( internet ) for my office. I have 3 vlans and I need 1 one to get 512Kb dedicated internet bandwidth. Need some advice on the configuration for the same.

Hello Renzil,

a basic QoS policy for your purpose would look like this:

class-map match-all PRIORITY

match ip address 101

!

policy-map BANDWIDTH

class PRIORITY

bandwidth 512

!

interface Serial0

service-policy output BANDWIDTH

!

access-list 101 permit ip x.x.x.x any

Your access list has to match the Vlan IP address range that you want to reserve bandwidth for. If you just want to reserve bandwidth for public addresses (the Internet), you can exclude private space addresses from your access list. In that case, prepend the following to the access list:

access-list 101 deny ip x.x.x.x 10.0.0.0 0.255.255.255

access-list 101 deny ip x.x.x.x 172.16.0.0 0.15.255.255

access-list 101 deny ip 192.168.0.0 0.0.255.255

Can you try and see if this works for you ?

Regards,
