Hi,
I'm having a problem using CBWFQ (LLQ actually) over a vbr-nrt ATM PVC. IOS is
12.2(8)T1 SP.
here's the config:
class-map match-any BE
match mpls experimental 0 1
match ip precedence 0 1
class-map match-any BC
match mpls experimental 3
match ip precedence 3
class-map match-any Interactive
match mpls experimental 5
match ip precedence 5
policy-map QoS-Policy
class Interactive
priority percent 20
class BC
bandwidth percent 30
random-detect
class BE
bandwidth percent 50
random-detect
interface ATM5/0
description *** ATM port ***
no ip address

no ip proxy-arp

interface ATM5/0.111 point-to-point
description *** 10Mb PVC ***

vbr-nrt 10000 10000 1

service-policy output QoS-Policy
!
PE4# show queue atm 5/0.111
'Show queue' not supported with FIFO queueing.
PE4# show policy-map int atm 5/0.111
PE4#
The 'show queue' command should give something like:
PE4#show queue f3/0
Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 0
Queueing strategy: weighted fair
Output queue: 0/1000/64/0 (size/max total/threshold/drops)
Conversations 0/0/256 (active/max active/max total)
Reserved Conversations 3/3 (allocated/max allocated)
Available Bandwidth 71000 kilobits/sec
Any ideas? The config looks right, according to the Overview and Configuring
docs on the Cisco website. If I attach this same service-policy to an FE
port, for example, I get the expected results, as seen above.
Note that the port is currently shut down. Do I need the port to be active?
