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.
