IPv4 Access Control Lists (ACLs)
Configuring Extended ACLs
Configuring Named, Extended ACLs
For a match to occur with an ACE in an extended ACL, a packet must have
the source and destination address criteria specified by the ACE, as well as
any IPv4 protocol-specific criteria included in the command.
Use the following general steps to create or add to a named, extended ACL:
1. Create and/or enter the context of a named, extended ACL.
2. Enter the first ACE in a new, extended ACL or append an ACE to the end
of an existing, extended ACL.
This section describes the commands for performing these steps. For other
