Software Download

The ELS100-24TX swi tch supports the ind u s try-standard Triv ial 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 or XMODEM software download is invoked via the Download

Software Menu using the console m enu s . A TFT P dow nl o ad c an a l so b e

invoked 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 Interfac es

The ELS100-24TX switch can be managed using any of the following

three methods:

•Serial console, out-of-band

An RS-232 connection, using a DB-9 connec tor , is sup porte d for o ut-

of-band switch management. Serial console management is per-

formed using a terminal, or computer system running communica-

tions software. See Chapter 3, “ELS100-24TX User Interface,” for

more detailed information on ma naging th e ELS1 00-24 TX swi tch via

the serial console.

•Telnet, in-band (ove r Ethernet)

The switch supports management thr ough a Te lnet conn ection us ing

the TCP/IP protocols. Telnet is perfor med usi ng an AS CII ter minal or

computer system running communications software. See Chapter 3,

“ELS100-24TX User Interface,” for more detailed information on

managing the switch via the serial console. Global password protec-

tion for changing the operating parameters of the switch is provided.

•SNMP-based network manager, in-band

The switch can be managed using SNM P, the most comm on protocol

used today for network management. Standard agent MIBs embed-

ded in the switch provide basic SNMP management through indus-

try-standard SNMP applications.

Management security protection is provided based on SNMP com-

munity names. See Chapter 5, “ SN M P M an age me nt,” for more infor-

mation.
