IPv4 Interface

Command Usage

•

An IP address must be assigned to this device to gain management access over the network or
to connect the switch to existing IP subnets. A specific IP address can be manually configured,
or the switch can be directed to obtain an address from a BOOTP or DHCP server. Valid IP
addresses consist of four numbers, 0 to 255, separated by periods. Anything other than this
format is not be accepted by the configuration program.

•

An interface can have only one primary IP address, but can have many secondary IP
addresses. In other words, secondary addresses need to be specified if more than one IP
subnet can be accessed through this interface. Note that a secondary address cannot be
configured prior to setting the primary IP address, and the primary address cannot be removed
if a secondary address is still present. Also, if any router/switch in a network segment uses a
secondary address, all other routers/switches in that segment must also use a secondary
address from the same network or subnet address space.

•

If bootp or dhcp options are selected, the system will immediately start broadcasting service
requests for all VLANs configured to obtain address assignments through BOOTP or DHCP. IP is
enabled but will not function until a BOOTP or DHCP reply has been received. Requests are
broadcast periodically by the router in an effort to learn its IP address. (BOOTP and DHCP
values can include the IP address, default gateway, and subnet mask). If the DHCP/BOOTP
server is slow to respond, you may need to use the

ip dhcp restart client

command to re-start

broadcasting service requests, or reboot the switch.

•

The only command parameters for the Craft port are ip-address and netmask.

NOTE

Management access and routing functions are supported for IPv4 interfaces, but only management
access is supported for IPv6 interfaces at this time.

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)#
