Tom,
Below is an example of how to use debug to answer these types of
questions.
r1#conf t
Enter configuration commands, one per line. End with CNTL/Z.
r1(config)#acc 111 permit ip any host 150.1.111.3
r1(config)#end
r1#
00:10:29: %SYS-5-CONFIG_I: Configured from console by console
r1#debug ip packet detail ?
<1-199> Access list
<1300-2699> Access list (expanded range)
<cr>
r1#debug ip packet detail 111
IP packet debugging is on (detailed) for access list 111
r1#traceroute 150.1.111.3
Type escape sequence to abort.
