Asynchronous Management

Asynchronous Management is a Compaq software option that allows you to monitor server health and receive traps through an asynchronous (modem) connection. This feature is essential to properly manage remote servers that may not be connected through a local area network. For servers with a LAN connection, this feature provides an important backup communication path in instances when the network is down.

Asynchronous Management runs on top of the operating system’s dial-up networking capability. To gain access to the managed server, a point-to-point protocol (PPP) connection is established, providing the necessary virtual networking transport to carry the full suite of SNMP management data.

If modem sharing is enabled, this same modem can be used to invoke IRC. IRC automatically detects incoming and outgoing PPP connections, forwarding the call on to the operating system. If, however, the connection is originating from an ANSI or telnet client, the call is accepted by the hardware-based, out-of- band management device: IRC.

To implement this configuration, configure asynchronous management as you would on a server without IRC. Once the operating system-based management utilities are configured and tested, enable IRC. If configured correctly, IRC should act as a communication “wrapper,” transparently allowing the modem to be used by both applications.

Since a wide body of documentation already exists on installing dial-up networking and asynchronous management, that information is not repeated here. Consult the instructions supplied with your operating system to install dial-up networking. See the Compaq Insight Manager User’s Guide for detailed instructions on setting up asynchronous management. IRC does not change the way these utilities are installed or configured.
