59 IPv4 Interface Commands

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.

Console(config)#interface vlan 1

Console(config-if)#ip address 192.168.1.5 255.255.255.0

Console(config-if)#
