QoS implementation

pannu3679 · ‎07-10-2008

Hi Guys,

I am trying to implement QOS between 2 sites

Brisbane router -------> point to point (with DCoS) ---------> Melbourne router

here is my configuration

Class-map match-all VideoTraffic

match access-group VideoTraffic

Class-map match-all VoiceTraffic

match access-group VoiceTraffic

Policy-map Tagging

Class VideoTraffic

set ip dscp ef

Class VoiceTraffic

set ip dscp af41

Policy-map QOS

Class VideoTraffic

bandwidth 2048

Class VoiceTraffic

priority 768

Class class-default

fair-queue

ip access-list extended VideoTraffic

Permit ip host <x.x.x.x (video conf. machine)> any

ip access-list extended VoiceTraffic

Permit Ip host <PABX IP> any

interface fast e 0/0 ( WAN Interface)

Bandwidth 4096

service-policy output QOS

interface fast e 0/1

service-policy input tagging.

when we applied the policy, i can see the traffic is classifed on show policy-map interface command. but video conf. machine showing packed drop.

I cannot see any packet drop on LAN and WAN interface.

is there anything wrong in config? do i need match protocol rtp video statement in class-map

VideoTraffic.

Please Help.

Thanks in advance.

hi mate

try this match statement on the server conf

ip access-list video

permit udp host x.x.x.x(srv) any range 16383 32767

if ur video server already do marking it will be easier

then do this clas-map

class-map match-ANY video

match ip dscp af41

match access-group name video

then apply it in ur policy map

DONT FORGET TRY TO MAKE UR POLICY MAP IN OUTBOUND DIRECTION OK

good luck
