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 from the

upgrade disk to an 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 that appears on the upgrade disk.

Tree Parameters

The ELS100-24TXM 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 act ivated,

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

Concepts,” for further information on using the Spanning Tree Proto col in

a network.

To configure Spanning Tree Parameters, do the following:

1. Select Switch Configuration Menu from the Main Menu.

2. Select Spanning Tree Configuration Menu.

3. Turn the switch Spanning Tree operation on or off by toggling the

Spanning Tree Protocol Enable option by pressing a.

4. Select Port Configuration.

The Spanning Tree Port Configuration Menu displays. Change the

parameters that display in this menu as required.

Configuring Spanning Tree parameters from their de-

fault can cause serious deterioration of network per-

formance.
