Current custom queue configuration:

1 1 protocol ip tcp port 3557

1 2 protocol ip tcp port www
1 1 protocol ip tcp port 100
1 2 protocol ip tcp port 8080
1 2 protocol ip tcp port 2000
1 3 protocol ip tcp port ftp
1 0 protocol ip tcp port 6699
1 2 protocol ip tcp port nntp
1 3 protocol ip tcp port smtp
1 1 protocol ip tcp port 81
1 1 protocol ip tcp port 1434
1 1 protocol ip udp port 1434
1 3 protocol ip udp port 540

huh???? How come protocols have migrated to another queues by themselves?

1 1 byte-count 6000
1 2 byte-count 3000

But it does not stop there.

ap7206-1#sh run | incl ^prior
priority-list 1 protocol ip high tcp smtp
priority-list 1 protocol ip high tcp www
priority-list 1 default low
priority-list 2 protocol ip high tcp ftp
priority-list 2 protocol ip high tcp ftp-data
priority-list 2 protocol ip high tcp www
priority-list 2 default low

ap7206-1#sh queueing priority
Current DLCI priority queue configuration:
Current priority queue configuration:

List Queue Args
1 low default
1 high protocol ip tcp port smtp
1 medium protocol ip tcp port www
2 low default
2 high protocol ip tcp port ftp
2 high protocol ip tcp port ftp-data
2 medium protocol ip tcp port www

(Please save the notes on the feasibility of such priority lists, it's the
owners of the network righs to do whatever is deemed necessary).

ap7206-1#sh ver
Cisco Internetwork Operating System Software
IOS (tm) 7200 Software (C7200-IO3S56I-M), Version 12.1(3a)T2, RELEASE
SOFTWARE (fc1)

Before that there was 12.0(7)XE1 image and behavior was exactly the same.

I'm sort of lost for words. Any pointers?

SY,
