Solved: Traffic Shapping on 881 Vlan switch , on the dialer interface

shivaleelag · ‎06-27-2013

Hi There ,

I am trying to apply policy shaping on dialer interface , but seems shaping has no effect.

I tried to apply polic-map on vlan 1 , but get error as " configuration-failed!! "

When applied on Fa0 , qos has no effect

when policy-map is applied on dialer interface , queing does happens but shaper does not work,

881#sh version

Hi Harsimrandeep,

Thank you so much for the reply. I will try to upgrae to 15.3 and retest.

I hope there is no issue with configs.

Between how about 887 ? I did see the same behaviour on 887 .

Best Regads

Shiva

Harsimrandeep Singh Pabla · ‎06-27-2013

Lets first upgrade the code, if issue is not resolved, we will revisit to configs.

Its not a platform issue, same behavior will be seen on all ISR-G2 routers.

Pabla

Hi Pabla,

Its working fine now.Qos with shaper and policer.

Little research on 881 releaved that we need to use F4 interface which is WAN interface in 881.

So the corrected config is:

interface FastEthernet4

no ip address

ip virtual-reassembly in

pppoe enable

pppoe-client dial-pool-number 1

no cdp enable

!

interface Vlan1

no ip address

!

Thank you so much for your time.

Best Regards

Shivaleela
