Command Usage
• If the ECN330-switch is directly connected to end node devices (or
connected to end nodes through 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 and subnetwork numbers of the segment that is connected to
that interface, and allows IP packets to be sent to or from the ECN330-
switch.
• Before any network interfaces are configured on the , 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 gain management access over the
network or to connect the ECN330-switch to existing IP subnets. A
specific IP address can be manually configured, or the ECN330-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.
• If the bootp or dhcp option is selected, IP is enabled but does not
function until a BOOTP or DHCP reply has been received. Requests are
broadcast periodically by the ECN330-switch in an effort to learn its IP
address. (BOOTP and DHCP values can include the IP address, default
gateway, and subnet mask).
• BOOTP or DHCP requests can be broadcast by entering the ip dhcp
restart client command, or by rebooting the ECN330.
Note: Before the primary IP address can be changed on an interface, the
current address must first be cleared with the no form of this command.
