Apply QoS policies to MPLS interfaces

Hello all,

We are deploying an MPLS transport network for our research project, and we are getting undefined errors about the QoS application over tunnel interfaces. The tunnel interfaces are those we configure between end points.

For example, if we apply a rate-limit to a tunnel interface, this is not applied, although the router anc CLI let configure the policy.

Does anybody know how to manage this kind of policies or shaping to MPLS?

Thanks for your help.


Re: Apply QoS policies to MPLS interfaces

I presume this is an input policy. First thing is when you apply the policy does the CLI produce any errors like "input policy is not supported on this interface". Second thing is normally a policy for qos is applied outbound not inbound.

Re: Apply QoS policies to MPLS interfaces


No, in fact, what we want to configure is output policies. For example, at the ingress LER of the MPLS cloud, we receive some traffic that we set it as an specific class of service, for example, "interactive traffic". Once the traffic is classified, we route it to the correct output tunnel interface, i.e., to the next LSR. It's at that interface where we want to set the policy, so.

When we set the policy, with the "service-policy output tunnel0", for example, the CLI doesn't return any message of error. In fact, it lets to configure it, and if we use the command "show policy-map interface tunnel0", CLI returns the configuration of the policy at that interface.

Thanks for your help.


Re: Apply QoS policies to MPLS interfaces

could u tell what qos config u try to apply. that class, and policy map and service policy configs for reference so that we could see what could be the probs.
