887VA ADSL - Service Policy brings down link

Nishant Jethwa

Have installed an 887VA on the end of a ADSL connection. The provider has specified EF 150 on the link. The router is configured using a Virtual Template.

If the Virtual Template has a service policy applied, we don't have connectivity to their main site - although the CD and PPP lights are lit. As soon as the service policy is removed, we have connectivity.

We've had three sites with the same problem. Two of the sites don't have QoS specified on the link but had the same problem if the service policy was applied.

Hardware - CISCO887VA-SEC-K9

Software - 15.1(4)M4

Try a Dialer interface instead of virtual template.

On setups historically we have used dialers, however the change has been dictated by our provider. They use Virtual Template so we have had to adopt the configuration on our end.

Whatever they use make no difference to you and to what goes on the wire.

Beside that, you can try solutions, go to who dictated you the configuration so can dictate a solution, or stay with the problem - up to you really.
