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 al rea dy bee n done, and ente ring the IP a ddress 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 t he Default Gateway f ield o n the Sys tem

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 display ed o n the Ge neral Informat ion

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 disa bled alterna tive i s activate d,

thereby maintaining the connection. See Appendix B, “Spanning Tree

Concepts,” for further informati on on using the Spa nn ing Tree Proto col i n

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”.
