Access List Numbers
The number you use to denote your ACL shows the type of access list that you are creating. Table 31-1
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.
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.
