AP1242 does not log access-list match

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?


Re: AP1242 does not log access-list match

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

Re: AP1242 does not log access-list match

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 any

cw-dp(config-ext-nacl)#permit ip host any log

cw-dp(config-ext-nacl)#deny ip any any log


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 any (10 matches)

30 permit ip host any (9 matches)

40 deny ip any any


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.

Re: AP1242 does not log access-list match

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?
