Bandwidth and Bandwidth Remaining cannot be both configured on a queue

Hi Everyone,

I have bumped into an issue when I trying to configure QoS no ASR9K router ver IOS XR 4.2.0. When I try to commit the configuration, I got error message below preventing me from configuring bandwidth and bandwidth-remaining on the queue. However, from the Cisco book QoS for IP/MPLS Network page 232, the configuration example for IOS XR shows both bandwidth and bandwidth-remaining on a queue. Plus, there is no restriction mentioned in the Cisco Configuration Guide for ASR9K router 4.2.0.

Could anyone help? Thanks.

hi Yuyang,

Please see the 4.2.0 QOS MQC guide.

http://www.cisco.com/en/US/docs/routers/asr9000/software/asr9k_r4.2/qos/configuration/guide/qc42hqos.html#wp1237156

It looks like your class CLASS3 is the problem. You can specify "bandwidth" or "bandwidth remaining" or

"shape average".

regards,

David

Thanks David. I found the restriction for the ASR9K Line card as specified in the document you provided.
