QoS IOS bug?

Unanswered Question
Jun 30th, 2010

Hi,

I have a 3Mb DSL service and the virtual interface doesn't read the

bandwidth allocation correctly.

Note I use QoS on the dialer with ppp multilink which creates a MLP Bundle and a  Virtual Interface which is listed as vi3

!
interface Dialer3
description PPPoA Dialer to iExec
bandwidth 3072
ip address negotiated
encapsulation ppp
dialer pool 3
dialer idle-timeout 0
dialer-group 3
no cdp enable
ppp authentication chap callin
ppp chap hostname [email protected]

ppp chap password 7 xxxxxxxxxxxx
ppp multilink
service-policy output QoS_Policy
end

sh policy-map int di3

Dialer3

  Service-policy output: QoS_Policy

    Class-map: Platinum_Queue (match-any)
      3661422 packets, 1024444024 bytes
      5 minute offered rate 0 bps, drop rate 0 bps
      Match: ip dscp ef (46)
        3661422 packets, 1024444024 bytes
        5 minute rate 0 bps
      Match: ip precedence 5

        Bandwidth 1013 (kbps) Burst 25325 (Bytes) --> correct showing
        (pkts matched/bytes matched) 0/0
        (total drops/bytes drops) 0/0

sh run int vi3

interface Virtual-Access3
bandwidth 3072
no ip address
service-policy output QoS_Policy
end

sh policy-map int vi3
Virtual-Access3

  Service-policy output: QoS_Policy

        (total drops/bytes drops) 0/0

sh run int vi 2 --> Interface associated with PPPoATM
!
interface Virtual-Access2
bandwidth 1024
no ip address
end
!

it is showing only 1024K bandwidth allocation on the vi3 and I have 3072 configured.

Does it matter, because the site is having phone related issues.

thanks,
