QoS on C1700


Which is the best way to implement QoS? I have 2 routers at 2 sites connected with a leased line with limited bandwidth. On Either location I have 2 LAN:s. One for the ordinary data-communication, and one other Lan with only 1 host on each LAN, 2 IP-enabled PBX:s. Like this

Site A:

LAN IP: (Router A fa0 has IP and is def gw on LAN)

Tele IP: (Router A e0 has IP, PBX has

S0: (router A s0 has IP

Site B:

LAN IP: (Router B fa0 has IP and is def gw on LAN)

Tele IP: (Router B e0 has IP, PBX has

S0: (router B s0 has IP

I want an policy on each router that prioritice packets coming in from e0 (Tele) when sending it out on s0. I dont want to care about source/destination IP-addresses, I want to trigger priority based on incoming interface.

Which is the right way do to this?

I was thinking of something like:

class-map match-all ipt

match input-interface ethernet0


policy-map ipt-policy

class ipt

<something here... what?>


int s0

service-policy output ipt-policy


Am I thinking right?

Thanks for your help!

Re: QoS on C1700

You can configure like this one...

policy-map ipt-policy

class ipt

bandwidth percent 40

queue-limit 50

Remaining configuration is Ok.
