I have tried ip access-list extended with "log" option. Filtering works well but nothing is logged. My AP is AIR-AP1242AG-E-K9 IOS Version 12.3(7)JA1
What could be wrong?

Which command did you try to check the logs? Did you see hits in the "show access-list" command?

Yes, "show access-list" displays the number of hits.
But "show log" does not display it and nothing is transmitted to syslog. I suppose this feature is not implemented well or not at all. It is not mentioned in the configuration guide - it is probably significant. I can configure "log" keyword in a statement but it is missing from the configuration at the time it should be of use. See example:
cw-dp#conf t
Enter configuration commands, one per line. End with CNTL/Z.
cw-dp(config)#no ip access-list extended ip-acl-working
cw-dp(config)#ip access-list extended ip-acl-working
cw-dp(config-ext-nacl)#permit udp any any eq bootps
cw-dp(config-ext-nacl)#permit ip host 10.126.104.2 any
cw-dp(config-ext-nacl)#permit ip host 10.126.104.4 any log
cw-dp(config-ext-nacl)#deny ip any any log
cw-dp(config-ext-nacl)#end
cw-dp#sh access-list ip-acl-working
Extended IP access list ip-acl-working
10 permit udp any any eq bootps
20 permit ip host 10.126.104.2 any (10 matches)
30 permit ip host 10.126.104.4 any (9 matches)
40 deny ip any any
cw-dp#
The "log" keywords remain in the configuration until is no match which should be logged. Then dissapear all "log" keywords.
Do you know where is the following "sl_def_acl" located?
Extended IP access list sl_def_acl
10 deny tcp any any eq telnet log
20 deny tcp any any eq www log
30 deny tcp any any eq 22 log
40 permit ip any any log
It is listed by the command "show access-lists" but is not included in the cofiguration listed by "show configuration".

P.S. Thanks for your answer and sorry for delay, I was too busy.

I am having this same issue even with the newest code. I have the ACL on a dot11radio0 sub-interface restricting inbound traffic. I need to be able to see the ports being attempted but not in the ACL so that I can add them to the ACL and cannot because the log statement disappears from the config. "Show access-lists" will indicate that the "deny ip any any" rule is denying packets, but does not log them. This is a "feature" I'm guessing? Has anyone opened case with TAC on this?
