prioritize video traffic (H.323) cisco 2960 switch

[saintrob]

Hi Forum,

I am urgently attempting to automatically prioritize video traffic (H.323) traffic and additional VoIP applications such as ‘Skype’ ensure uninterrupted service. Can I accomplish this objective by using the following Cisco’s (Modular QoS Command line) on a Cisco 2960 switch?


Example 1
access-list 1 permit (ip address of the camera)
class-map videoclass
match access-group 1
policy-map videopolicy
class videoclass
set ip dscp 46
interface FastEthernet 0/1
service-policy input video-policy
wrr-queue bandwidth 1,2,3,4
wrr-queue cos-map 4,6,7

Example 2
Class-map match-all VIDEO
Match access-group 190
!
policy-map INCOMING
class VIDEO
set ip dscp 46
police 1000000
!
…
!
interface FastEthernet 0/2
service-policy input INCOMING
!
access-list 190 permit ip host (ip address of the camera) any


Example 3

Basic QOS policy
mls qos

class-map CONFERENCE
match dscp 34 46 (can I include two dscp values ?)
policy-map QOS
class-map CONFERENCE
priority percent 40
class-map class-default
fair-queue

int gig0/1 <---your uplink
service-policy outbound QOS

int fa 0/1 <--- link to conference device
mls qos trust dscp

This will trust all dscp markings on fa0/1. It will also apply LLQ to your trunk (gi0/1) so that any traffic marked 34 will have 40% (adjustable) of the link reserved for it. All other traffic will get WFQ.

If any of the above examples does work, which would be your preferred solution? Or would you instead run the auto qos command on the serial interface of a 2911 router.

Router2911(config)# ip cef
Router2911(config)# interface serial0/0/0
Router2911(config-if)# ip address 194.6.0.244
Router2911(config-if)# encapsulation hdlc
Router2911(config-if)# bandwidth 1536 ---
Router2911(config-if)# auto qos voip trust

Any help would be greatly appreciated.

Regards
