Question about LLQ under IOS XR

Hi All,

I have a question regarding the excessive bandwidth allocation for LLQ under IOS XR. When configuring bandwidth remaining under class, is the bandwidth not used by priority queue at the moment part of the excessive bandwidth? Another question is, for priority confiugration, it forces an explicit policer to be configured, does it mean even during uncongested period the packet in priority queue that exceeds the rate will be discarded? Please see the code is per below.

policy-map OUT

class CLASS1

priority

police rate percent 50

class CLASS2

bandwidth percentage 20

bandwidth remaining percent 30

class CLASS3

bandwidth percentage 30

bandwidth remaining percent 60

class class-default

Thanks for the answer.

Question about LLQ under IOS XR

Hi Jin,

I am not sure about the first question. But for your second question, hardware platforms in Cisco support Always-ON LLQ which mean even if there is no congestion on the link and the bandwdith limit on LLQ is exceeded it drops the packets.
