Command Line Interface

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.
