Renewing DCHP – DHCP may lease addresses to clients indefi nitely 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 ser vice.
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.
