Hi All, I need your analysis based on the following Requirement and my configuration. Please advise....
Requirement : ----------------------- On the HQ switch I need to configure the following... 1) TO ensure cos value of "5" mapped to dscp ef 2) On interface g1/0/4 make sure all incoming CUPC signal traffic to cs3 & guarantee for 32k bandwidth . Anything in excess should be first marked down to dscp value of 8 before transmitting. 3) Policy a list of protocols for Presence. My Configuration: ------------------------- mls qos mls qos map policed-dscp 24 to 8 mls qos map cos-dscp 0 8 16 24 32 46 48 56 ip access-list extended SIG permit tcp any any eq 80 permit tcp any any eq 443 permit tcp any any eq 993 permit tcp any any eq 7993 permit tcp any any eq 143 permit tcp any any eq 389 permit tcp any any eq 2748 permit tcp any any eq 5060 permit udp any any eq 5060 permit udp any any eq 69 class-map match-any SIG match access-group name SIG ip access-list extended RTP permit access-group name 16384 32766 class-map match-any RTP match access-group name RTP policy-map CUPC class RTP set dscp ef class SIG set dscp cs3 police 32000 8000 exceed-action policed-dscp-transmit class class-default Under the trunk port to the router and servers I use "mls qos trust dscp" Under the phone ports I use... mls qos trust cos mls qos trust device-cisco-phone Under interface G1/0/3 which connects to uccx server with cupc client I apply int g1/0/4 service-policy input CUPC ================ Questions: ================ 1) Do I need to apply the service policy input command to the interface g1/0/4 which connects to uccx server with cupc client or do I need to put the service policy under g1/0/3 which connects to the PC ( test PC) on which cupc is also present? 2) what are the negative affects of QOS going wrong incase it is applied to the wrong interface? 3) Is my above configuration correct ? as we attempt LAN QOS in the end any checks we need to ensure to see everything works fine? 4) In my home lab I use Virtual machines with 2 switches . This does not technically simulate the exact scenario of the servers connecting to switch ports or the PC connected to switch port . Considering the following condition how do we simulate the above LAN QOS scenario? -MJ
