sh policy-map int fa 0 always shows 0 bps

[vincehgov]

I'm trying to configure QoS on my 877 router to give priority to voice packets.  However, when I do a show policy-map for WAN interface, all the classes show 0 bps.  When I do a show int for the WAN interface, I get the correct bandwidth util.

This 877 is meant for a home network.  I'm running a Cisco 7970 phone using phone-proxy back to my HQ. I'm also shaping the traffic.

Here is my config

Class Map match-any EF (id 1)

   Match ip  precedence 5

Class Map match-any class-default (id 0)

   Match any

  Policy Map To_WAN

    Class EF

      priority 128 (kbps)

    Class class-default

      bandwidth 384 (kbps)

  Policy Map To_WAN_Shaper

    Class class-default

      Average Rate Traffic Shaping

      cir 512000 (bps)

      service-policy To_WAN

interface FastEthernet0

switchport access vlan 102

no cdp enable

spanning-tree portfast

service-policy output To_WAN_Shaper

end

Here is my show int fa 0

Attach policy map to IP-enabled, not physical interface.

For a correctly deployed 877, that shoudl be an ATM or dialer interface, and would avoid the need for shaping.

Hi.  I'm sorry.  I'm using this for a cable modem.  I've made the FA0 the "external" interface and dropped it into it's own vlan.  Should I put the policy map on the vlan interface?

interface Vlan102

ip address dhcp

ip access-group 102 in

ip nat outside

ip virtual-reassembly

end

Yes, as indicated above. However, you may find that doing it on a proper 871 have less chances of encountering bugs or limitations.

[vincehgov]

Trying to do "service-policy output To_WAN_Shaper" on vlan interface returns "Configuration Failed!".

[paolo bevilacqua]

As indicated above, you should apply that on the WAN Ethernet of an 871, not an 877.

Or you can update IOS and hope tht the limitation has been removed (unlikely).
