Hi,
I got the following information during debug.
128K_LL#debug priority
Priority output queueing debugging is on
128K_LL#

Also, I found there is packet drops on the match ip address. The 'priority
80' is configured but there have a lot of dropped packets but default packet
have no drop. Why?
128K_LL#show policy-map interface serial 0/0.1

It looks like the guaranteed bandwidth 80 was dropped first instead of the
default packet? Why?
Thanks again.
