Solved: QOS on router Ethernet port

mccmhtac1 · ‎11-04-2011

My question is regarding assigning policy-maps to a interface.

Background:

The config I am posting is from a 2621 router. This routers Int fa0/0 connects to AT&Ts OPTEMAN 10Mbs Ethernet interface. The other end connects to our HQ router. At HQ is our PRIs and phone switches. I have configured QoS for this router, but don't I have to link them to the ingress interfacce (Int FA0/0)?

Here is the routers config:

-Thanks for the help

Hi,

of course you have to apply this policy-map to an interface otherwise it will serve no purpose.

You must apply outbound on WAN interface as you are shaping. As Joseph remarked above shaping is done if you can send at a rate higher than the access rate or CIR and the ISP is policing traffic above that rate.

Is it the case for you?

setting the bandwidth of an interface won't refrain it to send at the access rate.

Regards.

Alain

in and out is relative to the router. In this case you want to apply the policy to the traffic going out of the router toward your HQ. On the HQ end you want another policy applied out toward your remote site. You don't need a policy inbound on either router because the bottleneck is not at the router ( it is the speed of your wan).

If your WAN connection is only 10 Mbps and your LAN connection is 100 Mbps, you'll likely only need QoS on F0/0 egress.

PS:

If you get the full 10 Mbps on the WAN facing Ethernet there's no need to shape at 10 Mbps.

mccmhtac1 · ‎11-04-2011

I will get full 10Mbs on the WAN facing Ethernet, that is why I set it's port speed to 10Mbs.

Do I need to apply andy of this to an interface:

class-map match-any Voice-Traffic
  match ip dscp ef 
class-map match-any Voice-Signal
  match ip dscp cs3 
  match ip dscp af31 
class-map match-any Video
  match ip dscp af41 
!
!
policy-map Voip
  class Voice-Traffic
    priority 20
  class Voice-Signal
   bandwidth percent 25
  class Video
  class class-default
policy-map OPTEMAN10M
  class class-default
   shape average 100000000 40000 0

Based on the config I provided, what commands will I use to correctly apply the policies?

mccmhtac1 · ‎11-04-2011

pardon me for not understanding. but wouldn't that policy be 'in' not 'out'?

If f0/0 is the MPLS connection, out is correct.

cadet alain · ‎11-05-2011

Hi,

you can't apply a QoS policy with shaping or CBWFQ config inbound, it must be outbound and in your case on the interface towards MPLS.
