lan qos for cue to cucm

i have switch with cucm on port 1/0/4...

need to apply qos... as per question..

setup is wit 3 sites...and over framerelay..

site -3 have cue...

site-1 have cucm with this switch..

configure switch 1 with policies on the 3750 switch:

1: ensure cos value 5 is mapped to dscp ef /cue signal with cs3

2: in giga int 1/0/4, make sure all incoming cue signal traffic is marked with cs3  and guarantee to 8k bandwidth.

Anything in excess should be first marked down to dsco value of 8 before being transmitted.

3. use requirements listed in the cue section to deliver the list of protocols to be policed.

You do not need to do anything of that.

The defices already originate packets with the correctt DSCP value.

All you have to do is configure QoS on the WAN, and nothing else.

I don't think so this is valued. I tried to dig in SRND for cue qos. I don t think so no one will get full marks on LAN qos on ccievoice for this lab...  one of my friend tried to work around to capture that packets to find out valued solutions.. see this link below, its more helpfull.. Please reply if you find right solution..
