Used By
The name of the interface or VTY numbers to which this rule has been applied.
Type
The type of rule, either standard or extended.
Standard rules compare a packet’s source IP address against its IP address criteria
to determine a match. The rule’s IP address criteria can be a single I P address, or
portions of an IP address, defined by a wildcard mask.
Extended rules can examine a greater variety of packet fields to determine a
match. Extended rules can examine both the packet’s source and destination IP
addresses, the protocol type, the source and destination ports, and other packet
fields.
Access rules can be either standard rules or extended rules. IPSec rules have to
extended rules because they must be able to specify a service type. Externally
defined and unsupported rules may be either standard or extended.
