4 Command Line Interface

ip address

This command sets the IP address for the currently selected VLAN interface. Use the no form to restore the default IP address.

Syntax

ip address {ip-address netmask bootp dhcp} [secondary] no ip address

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.

bootp - Obtains IP address from BOOTP.

dhcp - Obtains IP address from DHCP.

secondary - Specifies a secondary IP address.

Default Setting

DHCP

Command Mode

Interface Configuration (VLAN)

Command Usage

If this router is directly connected to end node devices (or connected to end nodes via shared media) that will be assigned to a specific subnet, then you must create a router interface for each VLAN that will support routing. The router interface consists of an IP address and subnet mask. This interface address defines both the network number to which the router interface is attached and the router’s host number on that network. In other words, a router interface address defines the network and subnetwork numbers of the segment that is connected to that interface, and allows you to send IP packets to or from the router.

Before you configure any network interfaces on this router, you should first create a VLAN for each unique user group, or for each network application and its associated users. Then assign the ports associated with each of these VLANs.

You must assign an IP address to this device to gain management access over the network or to connect the router to existing IP subnets. 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.

An interface can have only one primary IP address, but can have many secondary IP addresses. In other words, you will need to specify secondary addresses if more than one IP subnet can be accessed via this interface.

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
