QoS for routing

[FernandoSP]

Hi,

I would need to implement QoS in a ADSL line with Dial-UP connection.

I've read that maybe with a router 877, i could have some problems for applying QoS in this dial-up line.

Have you ever tried to make it? If it wasn't possible to implement this option in 877, which alternative dou you suggest me?

Thanks.

Hi Raul,

In the ATM interface.

[rkhalil · Accepted solution]

you can apply QoS in the ATM subinterface without problems.

Config example:

class-map match-all MuMe

match access-group name Multimedia

class-map match-all BRONZE

match access-group name Trafico_BRONZE

class-map match-all SUC

match any

class-map match-all SILVER

match access-group name Trafico_SILVER

class-map match-all GOLD

match access-group name Trafico_GOLD

!

!

policy-map QOS

class MuMe

priority 2560

class GOLD

bandwidth 8

class SILVER

bandwidth 8

class BRONZE

bandwidth 17920

policy-map SUC

class SUC

shape average 100000000

service-policy QOS

!

policy-map MARK

class MuMe

class GOLD

class BRONZE

class SILVER
