Locally Generated Traffic QoS Values

Nicholas Poole · ‎04-26-2007

How can you change the QoS/DSCP values of locally generated router traffic?

A router connected to an MPLS provider needs to mark its own management traffic to fit the providers QoS policies. So I need to mark telnet/ssh and similar locally generated traffic (which wont pass in via a service-policy) as AF32 instead of the default CS6.

Hi there,

you can use a local policy to control the locally generated traffic:

ip local policy route-map CM

!

route-map CM permit 10

match ip address 101

set ip precedence

!

and the access-list 101, should define your desired traffic.

HTH, please rate if it does help,

Mohammed Mahmoud.

Hi,

In addition to Mohammed's clear and succinct response, if you need to set a specific DSCP value you can use "set ip dscp xx" in the route-map.

On platforms where "set ip dscp" is not supported you can use a combination of "set ip precedence" and "set ip tos" to achieve the same outcome.

Brad
