Software Download
The ELS100-24TXG 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 or XMODEM software download is invoked via the Download
Software Menu using the console menus. A TFTP download can also be
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 Interfaces
The ELS100-24TXG switch can be managed using any of the following
three methods:
• Serial console, out-of-band
An RS-232 connection, using a DB-9 connector, is supported for out-of-
band switch management. Serial console management is performed
using a terminal, or computer system running communications software.
See Chapter 3, “ELS100-24TXG User Interface,” for more detailed
information on managing the ELS100-24TXG 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
system running communications software. See Chapter 3, “ELS100-
24TXG User Interface,” for more detailed information on managing the
switch via the serial console. Global password protection for changing the
operating parameters of the switch is provided.
• SNMP-based network manager, in-band
The switch can be managed using SNMP, the most common protocol
used today for network management. Standard agent MIBs embedded in
the switch provide basic SNMP management through industry-standard
SNMP applications.
Management security protection is provided based on SNMP community
names. See Chapter 5, “SNMP Management,” for more information.
