numbers, 0 to 255, separated by periods. Anything outside this format will not
be accepted by the configuration program.
• If you select the bootp or dhcp option, IP is enabled but will not function until
a BOOTP or DHCP reply has been received. Requests will be broadcast
periodically by this device in an effort to learn its IP address. (BOOTP and
DHCP values can include the IP address, default gateway, and subnet mask).
• You can start broadcasting BOOTP or DHCP requests by entering an ip dhcp
restart command, or by rebooting the switch.
Notes:1.
Only one VLAN interface can be assigned an IP address (the default is
VLAN 1). This defines the management VLAN, the only VLAN
through which you can gain management access to the switch. If you
assign an IP address to any other VLAN, the new IP address
overrides the original IP address and this becomes the new
management VLAN.
2. Before you can change the IP address, you must first clear the current
address with the no form of this command.
Example
In the following example, the device is assigned an address in VLAN 1.
