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 client” command.
