It's because access-lists very rarely affect traffic generated by that
same device. Applies to outbound access lists, queueing, etc. That
single match against ICMP must have been caused by a device downstream
that crossed your queueing router, not the router itself.

Subject: CQ queueing counters
queueing counters are strange.
why?
-------------------------------
queue-list 1 protocol ip 1 list 120
queue-list 1 protocol ip 2 list 121
queue-list 1 default 0
queue-list 1 queue 1 byte-count 512
queue-list 1 queue 2 byte-count 5120
access-list 120 permit tcp any any eq telnet access-list 121 permit icmp
any any
-------------------------------
Protocol [ip]:
Target IP address: 160.6.12.1
Repeat count [5]: 1000
Datagram size [100]: 1500
Timeout in seconds [2]:
Extended commands [n]:
Sweep range of sizes [n]:
Type escape sequence to abort.
Sending 1000, 1500-byte ICMP Echos to 160.6.12.1, timeout is 2 seconds:
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
~~~~~~
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
!!!!!!!!!!!!!!!!!!!!
Success rate is 100 percent (1000/1000), round-trip min/avg/max =
380/381/400 ms
----------------------------
r4(config-if)#do sh queuein int s0/0
Interface Serial0/0 queueing strategy: custom
Output queue utilization (queue/count)
0/25 1/0 2/1 3/0 4/0 5/0 6/0 7/0 8/0
9/0 10/0 11/0 12/0 13/0 14/0 15/0 16/0
-----------------------------
Queue 2 is icmp traffic.
I wondered why counter2 is "1".
