QoS using precedence config question

jasonww04

I would like to use precedence values as a way to prioritize traffic. My idea is to have all RDP traffic at precedence 2, traffic from/to VLAN 1 at precedence 1 and all other traffic at precedence 0.

 

Is this a good idea and do I have the correct config?

 

This is how I would implement it.

ip access-list extended Priority2_traffic-ACL
 permit tcp any any eq 3389
 permit tcp any any eq 3390
 

ip access-list extended Priority1_traffic-ACL

permit ip 192.168.29.0 0.0.0.255 any

 

class-map match-all Priority2-CM
 match access-group name Priority2_traffic-ACL

class-map match-all Priority1-CM
 match access-group name Priority1_traffic-ACL
!
policy-map Priority-PM
 class Priority2-CM
  set ip precedence 2
 class Priority1-CM
  set ip precedence 1
 class class-default
  set ip precedence 0

 

interface GigabitEthernet0/1
 description WAN
 ip address x.x.x.x
 service-policy output Priority-PM

Hi Jason,

This is fine.

This configuration will apply the IP precedence value in outbound direction when packet flow out of Gi0/1 interface.

Hi Jason,

It will work definitely and don't wait for an RDP traffic to be generated don't know when. Just use an extended PING and use the TOS value in it 64 and ping to any device attached to the gig interface. 

Then the results shows in the "show policy-map interface" command. How many packet marked with IPP2 or IPP1.
