i have a router that IS A GATEWAY for internet , and another router which is Bras which is used to connect to Dslam
my request is , i want to gurantee didicted cir for specific vlan which is vlan 10
im using subinterface connect to router gateway which is the gateway of my vlan 10.
the problem is , i cant use policymap on subinterface !!!!!!!! it is not allowed to use it, im using router ios 7206 .
so i began to think in another solution which is applying the polivy map on the interface Gi0/1 as u see from my gigure below ,
but the problem is , the cpu takse high and rech up to 90 % , it consume 15 % after adding the polivy map >
i want a solution ,
could i use policy on the swithch ??? and consume the cpu on the other routers ???
is there any other optinal soultion to use QOS ?????
switch vlan 10 ===========routerGi0/1=============>internet
I believe you could find this link useful:
Hope it Helps,
have a look at this link:
rate limitting as its name implies, limits the bandwidth at a certain rate, with a burst. it doesnt guarantee a minimum bandwidth, nor does the shape average. but bandwidth command does it.
if you want a maximum of 1mbps extra to be available, add this command under policy map along with the bandwidth command:
police 16000000 exceed-action drop
fair-queue command enables qos Weighted Fair Queue, allowing other traffic flow to fairly share the bandwidth available. sorry u have to set it under the class-default, it is optional but good to be there.
