[c-nsp] QoS for videoconferencing

[Vincent De Keyzer]

Hello,

 

I need to set up QoS for a Internet access customer who wants to make sure
that his VC system gets, no matter what, 512kbps out of his total 3 Mbps.

 

I would like somebody to validate my config because I am not too familiar
with those things.

 

Here is my proposed config (customer has IP range x.y.z.224/28, VC system
will be .230):

 

Access router:

 

access-list 100 permit ip any host x.y.z.230 

access-list 199 deny   ip any host x.y.z.230

access-list 199 permit ip any x.y.z.224 0.0.0.7

!

class-map match-all AAUR02i-VideoConferencing

 match access-group 100

class-map match-all AAUR02i-Other

 match access-group 199

!

policy-map AAUR02i

 class AAUR02i-VideoConferencing

  bandwidth 512

 class AAUR02i-Other

  bandwidth 2560

!

int ATM 2/0.159

 service-policy output AAUR02i

 

CPE:

 

access-list 100 permit ip host x.y.z.230 any

access-list 199 deny   ip host x.y.z.230 any

access-list 199 permit ip x.y.z.224 0.0.0.7 any

!

class-map match-all AAUR02i-VideoConferencing

 match access-group 100

class-map match-all AAUR02i-Other

 match access-group 199

!

policy-map AAUR02i

 class AAUR02i-VideoConferencing

  bandwidth 512

 class AAUR02i-Other

  bandwidth 2560

!

int FastEthernet 0/1

 service-policy output AAUR02i

 

Does that look good?
