The Management Module and Advanced RMON Module are SNMP-conformant, slide-in modules that can manage an entire stock of units. SmartAgent software in the modules automatically gather and collate information about the stack. As well as supporting in band management via a network link, each modules has a serial port which allows out of band management. When installed, the Modules allow you to: Monitor and change the configuration of all units in the stack. Set up resilient links. You can protect a critical communication link against failure by ensuring that, should the main link fail, a standby link immediately and automatically takes over. Implement security features. For example, each user is assigned an access level that determines which management parameters the user can view or modify. Also, end station access can be restricted to a particular port. Monitor network performance. The management facility maintains statistics that assist you to monitor the operation of the network and perform predefined actions automatically when thresholds are exceeded. Poll other devices on the network. You can use one of several ways to access the management facility: Over the network, using an SNMP network manager, such as Transcend WorkGroup Manager for Windows (3C15000 series). Each network manager provides its own user interface to the management facilities. Using SNMP management, for example, you can configure traps to be sent to the management station if critical thresholds are exceeded. You can use SNMP running over the IP or IPX protocols. By connecting a VT100 terminal (or workstation with terminal emulation software) to the serial port on the Module. The terminal can be connected directly or remotely, via a modem. The VT100 management interface, which is a menu-driven user interface built into the Modules, is used. The VT100 management interface provides a subset of the features of SNMP management. Over a TCP/IP network, using a workstation running VT100 terminal emulation and Telnet. The VT100 management interface is used. By connecting a workstation running SLIP to the serial port, which allows you to use out-of-band Telnet or SNMP management. The workstation can be connected directly or remotely, via a modem. This method provides a way of managing the stack in situations where the LAN is not providing a reliable service, or where the network manager does not have direct LAN connectivity.
