That "trust" commands that you refer to only works in the switch, not in the router. For QoS to work correctly in the router, you'll need to setup class-map, policy-map, then apply the policy-map (outbound) to the serial interface.
Your router is currently running "advanced" code, so all QoS services for the router should be there.
Thanks for that. I've done just that, set up the class-maps, policy-maps etc... and applied these outbound to a frame-relay subinterface which necessitated setting up a frame-relay map-class and incorporating the policy-map within there.
So, "trust" cannot be defined on the 3845 routers then. So be it :)
i have a router that has one interface on the LAN and another going to the WAN. I simply want the LAN connected interface to 'trust' dscp values coming into the interface that have already been marked by switches in the LAN, and have those dscp values used by the service policy applied to the WAN connected interface.
Does the LAN connected interface need to be configured to 'trust' dscp values? I cannot apply the 'mls qos trust dscp' command to the router interface. Neither can I apply the 'mls qos' command globally to the router.
I'm assuming a router is a bit different from the switch, but could elaborate on this matter conceptually.
Cisco software routers (e.g. 28xx, 38xx, 72xx), usually don't modify the L3 ToS unless you configure them to do so. Whether they'll provide different service levels also usually depends on configuration except for WFQ (default on low speed WAN interface, e.g. T1/E1 or slower) which will proportion bandwidth to flows differently based on IP Precedence.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
