Configuring the Switch
2-14
2
Renewing DCHP – DHCP may lease addresses to clients indefinitely or for a
specific period of time. If the address expires or the switch is moved to another
network segment, you will lose management access to the switch. In this case, you
can reboot the switch or submit a client request to restart DHCP service.
Web – If the address assigned by DHCP is no longer functioning, you will not be
able to renew the IP settings via the Web interface. You can only restart DHCP
service via the Web interface if the current address is still available.
CLI – Enter the following command to restart DHCP service.
Managing Firmware
You can upload/download firmware to or from a TFTP server. By saving runtime
code to a file on a TFTP server, that file can later be downloaded to the switch to
restore operation. You can also set the switch to use new firmware without
overwriting the previous version.
Command Attributes
• TFTP Server IP Address – The IP address of a TFTP server.
• Destination File Name – The file name should not contain slashes (\ or /), the
leading letter of the file name should not be a period (.), and the maximum length
for file names on the TFTP server is 127 characters or 31 characters for files on
the switch. (Valid characters: A-Z, a-z, 0-9, “.”, “-”, “_”)
Note: Up to two copies of the system software (i.e., the runtime firmware) can be stored
in the file directory on the switch. The currently designated startup version of this
file cannot be deleted.
Downloading System Software from a Server
When downloading runtime code, you can specify the Destination File Name to
replace the current image, or first download the file using a different name from the
current runtime code file, and then set the new file as the startup file.
