ip address
This command sets the IPv4 address for the currently selected VLAN interface. Use the no form to
restore the default IP address.
Syntax
ip address {ip-address netmask | ip-address/prefix-length} [secondary]
[default-gateway ip-address] | bootp | dhcp}
no ip address [ip-address netmask [secondary] | dhcp]
ip-address - IP address
netmask - Network mask for the associated IP subnet. This mask identifies the host
address bits used for routing to specific subnets.
prefix-length - A decimal value indicating how many contiguous bits (from the left) of the
address comprise the network portion of the address. (Range: 0-32)
secondary - Specifies a secondary IP address.
default-gateway - The default gateway. (Refer to the ip default-gateway command which
provides the same function.)
bootp - Obtains IP address from BOOTP.
dhcp - Obtains IP address from DHCP.
Default Setting
DHCP
Command Mode
Interface Configuration (VLAN)
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.
