Configuring IPv4 ACLs
Access List Numbers
The number you use to denote your ACL shows the type of access list that you are creating.
lists the access-list number and corresponding access list type and shows whether or not they are
supported in the switch. The switch supports IPv4 standard and extended access lists, numbers 1 to 199
and 1300 to 2699.
supported in the switch. The switch supports IPv4 standard and extended access lists, numbers 1 to 199
and 1300 to 2699.
Note
In addition to numbered standard and extended ACLs, you can also create standard and extended named
IP ACLs by using the supported numbers. That is, the name of a standard IP ACL can be 1 to 99; the
name of an extended IP ACL can be 100 to 199. The advantage of using named ACLs instead of
numbered lists is that you can delete individual entries from a named list.

ACL Logging
The switch software can provide logging messages about packets permitted or denied by a standard IP
access list. That is, any packet that matches the ACL causes an informational logging message about the
packet to be sent to the console. The level of messages logged to the console is controlled by the logging
console commands controlling the syslog messages.

console commands controlling the syslog messages.
Note
Because routing is done in hardware and logging is done in software, if a large number of packets match
a permit or deny ACE containing a log keyword, the software might not be able to match the hardware
processing rate, and not all packets will be logged.
