•
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
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 segment that is connected to that interface, and
allows IP packets to be sent to or from the router.
• Before any network interfaces are configured on the router, 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.
• An IP address must be assigned to this device to gain management access
over the network or to connect the router to existing IP subnets. A specific IP
address can be manually configured, or the router 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 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, 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 in a network segment
