Overview
•Download system firmware
•Restart the system
There are three ways to access Local Management:
•Locally using a VT type terminal connected to the COM port.
•Remotely using a VT type terminal connected through a modem.
•In-band through a Telnet connection.
1.1.1The Management Agent
The management agent is an entity within the switch module that collects statistical information (e.g., frames received, errors detected) about the operational performance of the managed network. Local Management communicates with the management agent for the purpose of viewing statistics or issuing management commands. Local Management provides a wide range of screens used to monitor and configure the switch module.
1.1.2In-Band vs. Out-of-Band
Network management systems are often classified as either in-band or out-of-band. In-band network management passes data along the same medium (cables, frequencies) used by all other stations on the network. An example of an in-band network management system is the Enterasys Networks NetSight™.
Out-of-band network management passes data along a medium that is entirely separate from the common data carrier of the network, for example, a cable connection between a terminal and a switch module COM port. Enterasys Networks’ Local Management is an out-of-band network management system.
A module connected out-of-band to the management agent is not connected to the LAN. This type of connection allows you to communicate with a network module even when that module is unable to communicate through the network, for example, at the time of installation.
