Configuring the Switch
2
Web – Click System, IP. Specify the Management VLAN, set the IP Address
Mode to DHCP or BOOTP. Then click Apply to save your changes. The switch will
broadcast a request for IP configuration settings on the next power reset. Otherwise,
you can click Restart DHCP to immediately request a new address.
Note: 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.
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#config
Console(config)#interface vlan 1 3-85
Console(config-if)#ip address dhcp 3-43
Console(config-if)#end
Console#ip dhcp restart 3-41
Console#show ip interface 3-44
IP address and netmask: 10.1.0.54 255.255.255.0 on VLAN 1,
and address mode: User specified.
