Abbreviated as PAM,
Port to Application Mapping is a
feature of the
Cisco IOS
Firewall that allows you to customize
TCP or
UDP port
numbers for network services or applications. Using the port information, PAM
establishes a table of default port-to-application mapping information at the
firewall. PAM also supports host or
subnet specific port mapping, which allows you to apply PAM to a single host or subnet using standard access control lists
(
ACLs).
