G700 Media Gateway device management concerns itself with such parameters as standard port settings, port security, redundancy modes, gateway alarming, and flow control.
Management of the G700 and the S8300 is performed with either of two tools: the Device Manager (DM) or the Command Line Interface (CLI). The Device Manager is a Java applet that is served from a built-in Web server, and the CLI can be accessed via a Telnet session, either remotely across the network or locally via an Ethernet NIC-connected PC. In general, any operation that can be accomplished via the Device Manager can also be accomplished via the CLI. However, the converse is not true. That is, some operations can only be performed through the G700 CLI.
Each G700 Media Gateway and communications server device in a G700 Media Gateway system contains a Web server in the form of an http daemon that serves HTML pages and Java applets. When the user's Web browser is pointed toward the URL corresponding to the MG or CC device, the Web server sends an initial Web page and then loads the corresponding Java device manager applet into the browser.
The Device Manager applet, once loaded and executed, uses SNMP get operations to obtain and display information regarding status of particular elements of the device. For elements of the device that can be configured, the DM provides a GUI element to allow the user to specify values and then uses SNMP set operations to configure the device.
The managed device contains an SNMP Agent that provides access to a Management Information Base (MIB). The MIB contains nodes for all elements of the device that can be configured or whose status can be displayed. The MIB definition is established in a collaborative effort between the maintenance subsystem designer and the SNMP Agent designer.
The Device Manager presents the graphic image of a stack of Avaya MultiService devices and allows management of the entire stack, including G700s, as a single device.
The G700 Media Gateway provides a Command Line Interface (CLI) that provides access to all the data that is available through the Device Manager. A CLI interpreter parses the command and makes appropriate calls in the maintenance subsystem API to read or write the appropriate data.
The Avaya MultiService suite of applications provides tools for device management and monitoring. See Avaya MultiService and Avaya MultiService StandAlone (AMSA).
