<Caution>Named
access lists are not recognized by any software release prior to
Cisco IOS Release 11.2.
You can identify IP access lists with an alphanumeric string
(a name) rather than with a number (1 to 199). This feature allows
you to configure more than 99 standard IP and 100 extended IP access
lists in a router.
The key advantages of using named access lists are 1) the name
can be meaningful for documentation and maintenance and 2) you can
selectively delete specific lines within a named access list, making
it more flexible. If you identify your access list with a name
rather than a number, the mode and command syntax are
slightly different. Currently, only packet and route filters
can use a named list.
Consider the following before configuring named access lists:
- Access lists specified by name are not compatible with older
IOS releases.
- Not all access lists that accept a number will accept a name.
Access lists for packet filters and route filters on interfaces
can use a name.
- A standard access list and an extended access list cannot have
the same name.
To create a standard access list, use the table in Figure
beginning in global configuration mode.
To create an extended access list, use the table in Figure
beginning in global configuration mode.
Example of Named Access List
The following configuration creates a standard access list named
Internet_filter and an extended access list named marketing_group:
