Configuring IP Addressing, Interface Access, and System Information
5.1 Overview
This chapter describes the switch configuration features available in the CLI and web browser interface. For
help on how to use these interfaces, refer to:
_ Chapter 3, “Using the Command Line Interface (CLI)”
_ Chapter 4, Using the Secure Web Browser Interface”
Why Configure IP Addressing
? In its factory default configuration, the switch operates as a multi port
learning bridge with network connectivity provided by the ports on the switch. However, to enable specific
management access and control through your network, you will need IP addressing
Why Configure Interface Access and System Information
? The interface access features in the switch
operate properly by default. However, you can modify or disable access features to suit your particular needs.
Similarly, you can choose to leave the system information parameters at their default settings. However, using
these features can help you to more easily manage a group of devices across your network.
5.2 IP
Configuration
5.2.1
IP Address and Subnet Mask Overview.
Configuring the switch with an IP address expands your ability to manage the switch and use its
features. To configure IP addressing, use the CLI to manually configure the initial IP values.
5.2.2
IP Address and Subnet Mask.
By default, the switch is set to manual IP addressing. To arrange the manual IP addressing, use the
CLI to configure the initial IP values. If you want to configure the IP automatically then enable the
DHCP/Bootp server that has been set correctly with information to support the switch, and it will auto
configure the IP. (Refer to “DHCP/Bootp Operation” for information on setting up automatic
configuration from a server.). For information on how IP addressing affects switch performance, refer
to “How IP Addressing Affects Switch Operation”.
5.2.3
Default Gateway Operation.
The default gateway is required for tasks such as reaching off-subnet destinations or forwarding
traffic across multiple VLANs. The gateway value is the IP address of the next-hop gateway node for
the switch which is used if the requested destination address is not on a local subnet/VLAN. If the
switch does not have a manually-configured default gateway and DHCP/Bootp is configured, then the
default gateway value provided by the DHCP or Bootp server will be used. If the switch has a
manually configured default gateway, then the switch uses this gateway.
5.2.4
Configuring IP Address, Gateway, DHCP
Do one of the following:
_ To set the
bootmode
parameter to
Manual
and then manually enter the IP address and subnet mask
values you want for the switch.
_ To use DHCP or Bootp, use the “
set bootmode
” command to ensure that the
bootmode
parameter
is set to DHCP or Bootp (this enables the DHCP/Bootp), then refer to “DHCP/Bootp Operation”.
Syntax:
set bootmode=<dhcp|bootp|manual>
LE2425A
# set bootmode=dhcp
Save
and
restart
the switch. It will fetch an IP address from the DHCP Server.
5.3 DHCP/Bootp
Operation
5.3.1 Overview
DHCP/Bootp is used to provide configuration data from a DHCP or Bootp server to the switch. This
data can be the IP address, subnet mask, and default gateway. With either DHCP or Bootp, the
servers must be configured prior to the switch being connected to the network.
5.3.2
The DHCP/Bootp Process
Whenever the IP Config parameter in the switch is configured to
DHCP/Bootp
, or when the switch
is rebooted with this configuration then follow the steps below:
