Hi, QOS marking can be done on several places:
Servers traffic marking : on ccm enterprise parameters : DSCP for SCCP Phone Configuration ,DSCP for Cisco CallManager to Device Interface **** on 6500: match base on acl & ports **** on router's uplink to switch : (match protocol ... ) IOS : h323 dial-peers , mgcp ip qos ,sccp qos dscp ) ---so where is the best place for marking traffic ? (between marking base on 6500 and uplink of router which on is a valid config or both of them? (from lab point of view) --- what is "DSCP for Cisco CallManager to Device Interface" this parameter do? I cannot find clear info on what is this parameter marking from ccm help --- which types of traffic marks by ccm and witch does not ? ( h323 signalling ,sccp,sip ,h323 ras, rtp, sip, mgcp ??) do I need to write acl on 6500 and mark them on server ports? --- ipphones mark data vlan to dscp 0 , do I need to remark on data vlan and voice vlan again? (I see in some Doc that they match sip and h323 and then mark them again ) ANy useful tips that clear these doubts ? I'm a bit confused ,which methods I should mix and put as marking solution.
