If you lose your management connection, use a console connection and enter “show ip interface” to determine the new switch address.
CLI – Specify the management interface, and set the IP Address Mode to DHCP or BOOTP.
Console(config)#interface vlan 1 | |
| |
Console#ip dhcp restart | |
Console#show ip interface | |
IP address and netmask: 10.1.0.54 255.255.255.0 on VLAN 1, |
|
and address mode: User specified. |

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.
Console#ip dhcp restart | |
