Afternoon All,
I am using a Dell Force10 (S4810) in our data centre.
I have configured a service policy on the interface of our core switch that is facing our MPLS network.At the other end of the MPLS network is a remote site with Cisco phones deployed. All of the Call manager and voice gateways are connected to the force10 within the data centre so all of the voice traffic will traverse the MPLS.
The service policy is configured as an INPUT with an action to trust diffserv. I am using this configuration to ensure voice packets marked EF are given strict priority.
My question is, do I use the service policy on the interface facing the MPLS network with an INPUT, OUTPUT or both?
Configuration as follows:
policy-map-input trust-dscp
trust diffserv
INTERFACE Connected to MPLS:
interface te 0/39
service-policy input trust-dscp
Global configuration:
strict-priority unicast 2
Call Flow
Remote office phone ---access switch---distribution switch----MPLS network----DC core (force10)---voice gateway
Lastly, can I use multiple strict priority queues? For example, strict priority unicast 1 so that I can give AF marked traffic priority? I assume queue 2 will be serviced before 1?
Many thanks in advance for your help
Regards,
Jim
