I happened to be going through my router configs (that I inherited) and noticed I have an access list entry that I know is a mistake but what I don't know is if it is effecting routing.
I found:
access list 10 permit 65.
Will this allow any traffic starting with 65. or is it meaningless?
The correct line was entered just below it.
Cisco 1721 IOS 12.3
Thanks.
Well first it should not even be there as it is not a valid access- list. You can either put in a hostname, IP address, the word host, or any, and I have no clue what 65 would even refer to. Second, unless it is applied as a distribution list within a routing protocol, the most it would do is impact a certain kind of traffic. So to answer your question, I would consider looking at the counters on that ACL by adding the 'logging' keyword, and see if anything is matching. Else I would think you can remove.
On current IOS levels (I just tried it on a 7206), that command doesn't even take....
