This read-write INTEGER enables or disables automatic allocation of the TCP port used to identify a managed remote unit's channel; rows in the associated TCP port table can only be created or deleted while this is enabled. Admins turn this on when they want the access node to dynamically assign TCP ports for remote-unit Telnet/HTTP management channels rather than managing them manually. For example, setting zxAnRuChannelTcpPortAutoAllocEn to enabled(1) allows the system to automatically assign a port such as 25001 the next time a new remote unit's management channel is created.
