Port Mapping is a security feature, which controls communication between peer users. Each session 
comprises a session ID, a set of user ports, and/or a set of network ports. The user ports within a session 
cannot communicate with each other and can only communicate via network ports. In a port mapping 
session with user port set A and network port set B, the ports in set A can only communicate with the ports 
in set B. If set B is empty, the ports in set A can communicate with rest of the ports in the system.

A port mapping session can be configured in the unidirectional or bidirectional mode. In the unidirec-
tional mode, the network ports can communicate with each other within the session. In the bidirectional 
mode, the network ports cannot communicate with each other. Network ports of a unidirectional port 
mapping session can be shared with other unidirectional sessions, but cannot be shared with any sessions 
configured in the bidirectional mode. Network ports of different sessions can communicate with each 
other.

This chapter describes the port mapping security feature and explains how to configure the same through 
the Command Line Interface (CLI).

Configuration procedures described in this chapter include:

• Creating/Deleting a Port Mapping Session—see 

 or 

• Enabling/Disabling a Port Mapping Session—see 

.

• Configuring a Port Mapping Direction—see 

 

and 

• Configuring an example Port Mapping Session—see 

• Verifying a Port Mapping Session—see
