CM-1 Management Capabilities

An ASCII terminal can be used as a supervision terminal to manage the CM-1 module. The supervision terminal is connected to one of the RS-232 asynchronous serial supervisory ports (one port is located on the CM-1 module itself and the second port is located on the interface module serving the CM-1 module).

The CM-1 module operates as an interface module that does not process the management information, but only transfers the management traffic transparently to the modules installed in the LRS-24. Therefore, the supervision terminal is controlled by the software stored in the managed modules, and the management capabilities depend on the capabilities of the managed modules.

For a description of the management activities supported by a terminal connected to the CM-1 module, refer to the Installation and Operation Manuals available for the modules installed in LRS-24.

CM-2 Management Capabilities

The CM-2 module enhances the management capabilities available to the user by including three different management functions:

•SNMP management. For SNMP management, the CM-2 module communicates via an additional management interface located on the interface module serving the CM-2 module. Currently, two types of interfaces are available: an Ethernet 10BaseT interface (for UTP and STP media), and an Ethernet 10Base2 interface (for coaxial media). This configuration is illustrated in Figure 1-8.

•SNMP management communication with an LRS-24 module that includes an SNMP agent is handled by an internal SNMP agent and bridge/router located on the CM-2 module. To enable SNMP management of modules without SNMP agents, the CM-2 module includes a proxy agent that converts the management traffic to the proprietary internal protocol used to manage such modules.

•Management by an ASCII terminal operating as a supervision terminal. The terminal, which is controlled by the software stored in the managed modules, connects to the serial RS-232 asynchronous supervisory port located on the CM-2 module (see Figure 1-8).The management capabilities available through the terminal are similar to those available through the CM-1 module.

•Management by means of Telnet. The CM-2 also supports the Telnet protocol. This enables remote management via the same command line interface used with a supervision terminal. Telnet uses TCP/IP communication through the Ethernet port of the CM-2 card.

•Management via RS-232by Slip Protocol with SNMP management.
