Usage Information
When you use the log option, the CP processor logs details about the packets that match. Depending
on how many packets match the log entry and at what rate, the CP may become busy as it has to log
these packets’ details.
NOTE: When ACL logging and byte counters are configured simultaneously, byte counters may
display an incorrect value. Configure packet counters with logging instead.

Commands
deny — configures a filter to drop packets.
permit — configures a filter to forward packets.
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.
