Renewing DCHP
– DHCP may lease addresses to clients indefinitely or
for a specific period of time. If the address expires or the stack is moved to
another network segment, you will lose management access to the stack. In
this case, you can reboot the stack or submit a client request to restart
DHCP service via the CLI.
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, or copy
files to and from switch units in a stack. 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. You must specify the method of file
transfer, along with the file type and file names as required.
Command Attributes
• File Transfer Method – The firmware copy operation includes these
options:
- file to file
– Copies a file within the switch directory, assigning it a new
name.
- file to tftp

- tftp to file
– Copies a file from a TFTP server to the switch.
•
TFTP Server IP Address
