Sunfire B1600 manual Console#ip dhcp restart Console#show ip interface

If the address assigned by DHCP is no longer functioning, you will not be able to renew the IP settings through the web interface. You can only restart the DHCP service through the web interface if the current address is still valid.

Note – If you lose your management connection, use a console connection and the show ip interface command to determine the new switch address.

Note – The Client ID specified in this menu will be overwritten by the SC the next time the System Controller, or the switch itself, is rebooted. The Client ID field will be removed from the next firmware release.

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.

Type the following command to restart DHCP service:

Console#ip dhcp restart
