Hi,

Can any one tell me what the "check=" means when viewing an access list ?

show access-list 1
permit 1.2.3.4, wildcard bits 0.0.0.1 (232 matches) check=2781
permit 1.2.3.4, wildcard bits 0.0.0.1 check=3013

I cant find anything in google about my question.

Regards
Alex

Hi Alex,

This is just a complete guess. :)

232+2781=3013

So, there was 3013 checks against the ACL.  Out of that there was 232 matches and 2781 no matches.

Thanks,

Reza

Hi Reza.

I think you are right seems to be a maths thing on old IOS in an old 2950 switch.

Only seems to clock up on lines with a wild card mask configured, another access list in the same box shows your thinking to be correct. :)

permit X.Y.45.42, wildcard bits 0.0.0.1 check=7192
permit X.Y.45.44, wildcard bits 0.0.0.3 check=7192
permit X.Y.45.48, wildcard bits 0.0.0.1 (7192 matches)

PS - Hope you are well
