2801 QoS on sHDSL card

I can't find the answer on the web and I want to know if it is supported.

I have a 2801 with a sHDSL WAN card.

1) When I configure

class-map match-all IncATM

match input-interface ATM0/0/0

policy-map IncIF

class IncATM

set ip dscp af41

the dscp is not being modified, but it works fine on Eth interfaces.

2)I can't apply a shape policy on ATM interface (or sub-if).

1. please do use match input-interface to sub-id, not main interface.

2. Which kind of shaping, why can't you attach ?

Re: 2801 QoS on sHDSL card

1) I've already tried that and didn't work. This is the config:

interface ATM0/0/0

bandwidth 4096

no ip address

load-interval 30

no atm ilmi-keepalive

!

interface ATM0/0/0.1 point-to-point

bandwidth 4096

ip address 15.15.15.1 255.255.255.0

atm route-bridged ip

pvc 0/35

vbr-rt 4096 4096 1

encapsulation aal5snap

!

2) When I try to attach this policy to the pvc I receive a message saying something like GTS is not available.

policy-map out1

class MC

bandwidth 300

shape 300

Hi,

which exact IOS are you using? If no need for 12.4 T features, please upgrade to 12.4(3j) and try again.

Re: 2801 QoS on sHDSL card

Hi,

I'm facing a problem SHDSL, I have a 2811 and my controller is flapping UP-DOWN-UP-DOWN. Which is your config. for the controller DSL ? Here's my config.

controller DSL 0/0/0

mode atm

line-term cpe

line-mode auto

dsl-mode shdsl symmetric annex B

Have you an idea, why is not stable?

I really don't know much about it, but you must be sure to match the config to the other end.

I used a 4 wire config, connected to a DSLAM:

!

controller SHDSL 0/3/0

dsl-group 0 pairs 0, 1

shdsl 4-wire mode enhanced

shdsl annex B

shdsl rate auto

!

!
