### Loading the PortAssist Manager Communication Agent: AIX

Use this procedure to start the PortAssist Manager communication agent and, if you so choose, to ensure it is automatically loaded each time the system is initialized. PortAssist Manager can monitor and manage your Digi adapters. To read about and use PortAssist Manager, go to PortAssist Manager Users Guide.

#### Requirements

The drivers for the Digi adapters to be monitored by PortAssist Manager must have already been installed.

#### Procedure

1. At a root prompt on the AIX system, change the working directory to /usr/lbin/tty with the following command:

   `cd /usr/lbin/tty`

2. Determine how you will want to use the communication agent.

If you want to manually load the communication agent (without booting), enter at the command line prompt:

> `./agent [UDP_Port_Number] &`

where `UDP_Port_Number` is the number of the communication agent's UDP port, if different from the default.

Note: The default UDP number is 2362, which was assigned to Digi by the Internet Assigned Number Authority (IANA). Although you can change this port number, it should not be necessary. If another application uses it, the best way to resolve the conflict is to reconfigure the application to use another UDP port number, one that has not been assigned by the IANA.

If you want the communication agent automatically loaded at startup, continue with the next step.

3. Enter the command:

> `mkitab “pamagent:2:respawn:/usr/lbin/tty/agent > /dev/console 2>&1”`

Note: If you no longer want the communication agent loaded automatically, delete the following from the /etc/inittab file:

> `“pamagent:2:respawn:/usr/lbin/tty/agent > /dev/console 2>&1”`
