Interface Configuration (VLAN)
Command Usage
• You must assign an IP address to this device to gain management access
over the network. You can manually configure a specific IP address, or
direct the device to obtain an address from a BOOTP or DHCP server.
Valid IP addresses consist of four 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.
Note: 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.
Example
In the following example, the device is assigned an address in VLAN 1.
