The MAC ACL supports an inverse mask; therefore, a mask of ff:ff:ff:ff:ff:ff allows
entries that do not match and a mask of 00:00:00:00:00:00 only allows entries that
match exactly.

IP Prefix List Commands
When you create an access-list without any rule and then apply it to an interface, the ACL behavior reflects implicit permit.
To configure or enable IP prefix lists, use these commands.
clear ip prefix-list
Reset the number of times traffic mets the conditions (“hit” counters) of the configured prefix lists.
Syntax
clear ip prefix-list [prefix-name]
Parameters
prefix-name (OPTIONAL) Enter the name of the configured prefix list to clear only counters for
that prefix list, up to 140 characters long.
Defaults Clears “hit” counters for all prefix lists unless a prefix list is specified.
