Application Protocol Column
This column contains the name of the application protocol, and the names of th e
protocol types. For example, the FTP and the TFTP entries are found unde r the
File Transfer protocol type.
Port Type Column
This list appears if the router is running a CiscoIOS image that allows you to
specify whether this port map entry applies to TCP or to UDP traffic.
Port Column
This column contains the port number. For example the system-defined entry for
HTTP would have the port number 80 in this column. A user-defined entry for
HTTP might have the port number 8080 or another custom-defined number in this
column.
Protocol Type Column
A row in this column displays one of the following values:
•User-Defined—The entry contains a nonstandard mapping betwee n a
protocol and protocol number. The entry could be associated with a h ost IP
address identified by the access control list (ACL) whose number is displayed
in the Access List column.
•System-Defined—The entry contains a standard, registered mapping
between the protocol and protocol number, such as tftp 69, or smtp 25.
System-defined entries cannot be edited or deleted. System-defined entries
contain no value in the Access List column because they apply to all hosts on
the network.
Access List Column
A PAM entry applies to a single host, defined by a standard ACL. This column
displays the number of the ACL used to identify the host to which the PAM entry
applies. If you want to view the ACL that identifies the host, go to Additional
Task s > ACL Editor > Access Rules. Then click the number of the ACL that you
saw in this window.
