Named and numbered standard ACL

A named, standard ACL is identified by an alphanumeric string of up to 64 characters and is created by entering the Named ACL (nacl) context.

A numbered, standard ACL is identified by a number in the range of 1 - 99 and is created without having to leave the global config context. Note that the CLI command syntax for creating a named ACL differs from the command syntax for creating a numbered ACL.

For example, the first pair of entries below illustrate how to create (or enter) a named, standard ACL and enter an ACE. The next entry illustrates creating a numbered, standard ACL with the same ACE.

switch(config)# ip access-list standard Test-List

switch(config-std-nacl)# permit host 10.10.10.147

switch(config)# access-list 1 permit host 10.10.10.147

Once a numbered ACL has been created, it can be accessed using the named ACL method. This is useful if it becomes necessary to edit a numbered ACL by inserting or removing individual ACEs. (Inserting or deleting an ACE is done by sequence number, and requires the Named ACL (nacl) context.) The switch allows a maximum of 2048 unique ACL identities (IPv4 and IPv6 combined). See Monitoring shared resources.

NOTE:

See Configuring standard ACLs for a summary of standard ACL commands. For a summary of all IPv4 ACL commands, see IPv4 Access Control Lists (ACLs).
