3 Configuring the Switch

Using DHCP/BOOTP

If your network provides DHCP/BOOTP services, you can configure the switch to be dynamically configured by these services.

Web – Click System, IP Configuration. Specify the VLAN to which the management station is attached, set the IP Address Mode to DHCP or BOOTP. Click Apply to save your changes. Then click Restart DHCP to immediately request a new address. Note that the switch will also broadcast a request for IP configuration settings on each power reset.

Figure 3-7 DHCP IP Configuration

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, and then enter the “ip dhcp restart” command.

Console#config
Console(config)#interface vlan 1		4-166
Console(config-if)#ip address dhcp		4-309
Console(config-if)#end
Console#ip dhcp restart		4-311
Console#show ip interface		4-311
IP address and netmask: 192.168.1.1 255.255.255.0 on VLAN 1,
and address mode:	User specified.
Console#

Renewing DHCP – 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 via the CLI.
