Enterasys Networks VH-4802 manual Software Download, Non-Volatile Parameter Storage

Software Download

The VH-4802 switch supports the industry-standard Trivial File Transfer Protocol (TFTP) for downloading software to the switch. All switch software is stored in a 2 MB sectored flash ROM. The download feature allows you to easily install software upgrades to the unit. Software can alternatively be downloaded via the serial console port using the XMODEM protocol.

A TFTP software download is invoked via the Management Setup Menu using the console menus. A TFTP download can also be invoked using the on-board Web agent or via SNMP.

Non-Volatile Parameter Storage

Important operating parameters such as IP addresses, Spanning Tree configuration, and management security parameters, are stored in non- volatile flash memory. These values are retained when the switch experiences power interruptions or is powered down for normal maintenance.

Configuration and Management Interfaces

The VH-4802 switch can be managed using any of the following methods:

•Serial console, out-of-band

An RS-232 connection, using a DB-9 connector, is included on the rear panel for system management. Serial console management can be performed out-of-band using a terminal or computer running communications software. You can connect directly to the RS-232 port on the rear panel, or make a connection via a modem. See the Management Guide for information on managing the VH-4802 switch via the serial console.

•Telnet, in-band (over Ethernet)

The switch supports management through a Telnet connection using the TCP/IP protocols. Telnet is performed using a terminal or computer running communications software. See the Management Guide for information on managing the system via Telnet. Global user name and password protection for changing the operating parameters of the switch is provided.

•Web-based network manager, in-band

The system can be managed over HTTP protocol with a Web browser (Internet Explorer 4.0 or above, or Netscape Navigator 4.0 or above). Standard agent MIBs embedded in the switch provide basic SNMP management through an embedded graphic interface.
