58 Configuring & Monitoring The Switch ELS100-24TXG
Downloading Via TFTP
To perform a TFTP download, you must first configure the ELS100-
24TXG switch. This consists of programming the switch with an IP
address, if this has not already been done, and entering the IP address of
the TFTP server and the name of the upgrade file. To program the switch
IP address, go to the System Configuration Menu which is accessible
from the Main Menu screen.
To download switch software via TFTP, do the following:
1.
Select TFTP Server IP Address from the Download Software Menu.
2.
Enter the TFTP server IP address and press [Enter].
3.
Select TFTP File Name and enter the file name to be downloaded
from the TFTP server.
4.
If necessary, configure the address of an IP gateway to reach the
server from the switch using the Default Gateway field on the System
Configuration Menu.
5.
Configure the TFTP server by copying the download file to the
appropriate directory and starting the server.
6.
Select Start TFTP Download and press [Enter].
To verify that the TFTP download has been successfully completed,
note the software version level displayed on the General Information
screen accessible from the Main Menu. This number should match
the version number of the downloaded file.
Configuring Spanning Tree Parameters
The ELS100-24TXG switch supports the IEEE 802.1D Spanning Tree
Protocol. This protocol allows redundant connections to be created
between LAN segments for purposes of fault tolerance. Two or more
physical paths between different segments can be created through the
switch, with the Spanning Tree Protocol choosing a single path at any
given time and disabling all others.
If the chosen path fails for any reason, a disabled alternative is activated,
thereby maintaining the connection. See Appendix B, “Spanning Tree
Concepts,” for further information on using the Spanning Tree Protocol in
a network.
For a TFTP download, the path to the file must be in-
cluded in its name. For example, if the upgrade file
name is filename.bin and it resides in the directory /
usr/tftp on the TFTP server, then you must enter the
TFTP file name as: “/usr/tftp/filename.bin”.
