ACL
A named ACL is identified
by a character string name,
which can be specified to
reference the ACL. Named
ACLs are easy to identify
and remember.
The AR1200-S supports
flexible ACL naming modes.
You can also specify a number
for a named ACL. If no ACL
number is specified for a
named ACL, the system
allocates an ACL number to
the named ACL.
Table 10-2 shows information that can be used by basic ACLs, advanced ACLs, and Layer 2
ACLs to define rules. Advanced ACLs can define rules based on IP version information and the
type of the protocol over IP, such as Generic Routing Encapsulation (GRE), Internet Group
Management Protocol (IGMP), IPinIP, Open Shortest Path First (OSPF), Transmission Control
Protocol (TCP), User Datagram Protocol (UDP), and Internet Control Management Protocol
(ICMP).
