Software Download
The ELS100-24TX 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 ELS100-24TX switch can be managed using any of the following
three methods:
• Serial console, out-of-band
An RS-232 connection, using a DB-9 connector, is supported for out-
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 managing the ELS100-24TX 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 an ASCII terminal 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 SNMP, the most common 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, “SNMP Management,” for more infor-
mation.
