Switch Information – Basic Settings

The

Switch Information

window shows the switch’s

MAC Address

(assigned by the factory

and unchangeable). In addition, the

Boot PROM

and

Firmware Version

numbers are shown.

This information is helpful to keep track of PROM and Firmware updates and to obtain the

switch’s MAC address for entry into another network device’s address table – if necessary.

You may assign a System Name, System Location, and System Contact. If any changes or

additions are made, click

Apply

.

Switch IP Settings

Switch IP settings may initially be set using the console interface prior to connecting to it

through the Ethernet. If the switch IP address has not yet been changed, read the Introduction

of the CLI Reference or skip ahead to the end of this section for a quick description of how to

use the console port and CLI IP settings commands to establish IP settings for the switch.

To change IP settings using the web manager you must access the

IP Address

menu located

in the

Configuration

folder.

To configure the switch’s IP address:

Open the

Configuration

folder and click the

IP Address

link. The web manager will display

the

Switch IP Settings

menu below.

Configure Switch IP Settings

NOTE:

the switch’s factory default IP address is 10.90.90.90

with a subnet mask of 255.0.0.0 and a default gateway of

0.0.0.0.

To manually assign the switch’s IP address, subnet mask, and default gateway address:

-Select

Manual

from the

Get IP From

drop-down menu.

-Enter the appropriate IP address and subnet mask.

-If you want to access the switch from a different subnet from the one it is installed on, enter

the IP address of the gateway. If you will manage the switch from the subnet on which it is

installed, you can leave the default address (0.0.0.0) in this field.

If no VLANs have been previously configured on the switch, you can use the default VLAN

Name “default”. The default VLAN contains all of the switch ports as members.

If VLANs

have been previously configured on the switch, you will need to enter the VLAN Name of the

VLAN that contains the port connected to the management station that will access the switch.

The switch will allow management access from stations with the same VLAN Name listed

here.

To use the BOOTP or DHCP protocols to assign the switch an IP address, subnet mask,

and default gateway address:

Use the

Get IP From: <

Manual

>

pull-down menu to choose from

BOOTP

or

DHCP

. This

selects how the switch will be assigned an IP address on the next reboot.

The Switch IP Settings options are:

Parameter

Description

BOOTP

The switch will send out a BOOTP broadcast request when it is powered up.

The BOOTP protocol allows IP addresses, network masks, and default

gateways to be assigned by a central BOOTP server. If this option is set, the

Switch will first look for a BOOTP server to provide it with this information

before using the default or previously entered settings.

DHCP

The switch will send out a DHCP broadcast request when it is powered up.

The DHCP protocol allows IP addresses, network masks, and default

gateways to be assigned by a DHCP server. If this option is set, the switch

will first look for a DHCP server to provide it with this information before using

the default or previously entered settings.

Manual

Allows the entry of an IP address, Subnet Mask, and a Default Gateway for

the switch These fields should be of the form xxx xxx xxx xxx where each

D-Link DES-6500 Layer 3 Stackable Gigabit Ethernet Switch

the switch. These fields should be of the form xxx.xxx.xxx.xxx, where each

xxx is a number (represented in decimal form) between 0 and 255. This

address should be a unique address on the network assigned for use by the

network administrator. The fields which require entries under this option are

as follows:

Subnet Mask

A Bitmask that determines the extent of the subnet that the Switch is on.

Should be of the form xxx.xxx.xxx.xxx, where each xxx is a number

(represented in decimal) between 0 and 255. The value should be 255.0.0.0

for a Class A network, 255.255.0.0 for a Class B network, and 255.255.255.0

for a Class C network, but custom subnet masks are allowed.

Default Gateway

IP address that determines where packets with a destination address outside

the current subnet should be sent. This is usually the address of a router or a

host acting as an IP gateway. If your network is not part of an intranet, or you

do not want the Switch to be accessible outside your local network, you can

leave this field unchanged.

VLAN Name

This allows the entry of a VLAN Name from which a management station will

be allowed to manage the switch using TCP/IP (in-band via web manager or

Telnet).

Management stations that are on VLANs other than the one entered

in the VLAN Name field will not be able to manage the switch in-band unless

their IP addresses are entered in the Security IP Management menu.

If

VLANs have not yet been configured for the switch, The default VLAN Name

contains all of the switch’s ports.

There are no entries in the Security IP

Management table, by default

−

so any management station that can connect

to the switch can access the switch until either a management VLAN is

specified or Management Station IP Addresses are assigned.

Setting the Switch’s IP Address using the Console Interface

Each Switch must be assigned its own IP Address, which is used for communication with an

SNMP network manager or other TCP/IP application (for example BOOTP, TFTP). The

switch’s default IP address is 10.90.90.90. You can change the default Switch IP address to

meet the specification of your networking address scheme.

The IP address for the switch must be set before it can be managed with the Web-based

manager. The switch IP address can be automatically set using BOOTP or DHCP protocols, in

which case the actual address assigned to the switch must be known.

The IP address may be set using the Command Line Interface (CLI) over the console serial

port as follows:

Starting at the command line prompt, enter the commands

config ipif System ipaddress

xxx.xxx.xxx.xxx/yyy.yyy.yyy.yyy

. Where the

x

’s represent the IP address to be assigned to

the IP interface named

System

and the

y

’s represent the corresponding subnet mask.

Alternatively, you can enter

config ipif System ipaddress xxx.xxx.xxx.xxx/z

. Where the

x

’s

represent the IP address to be assigned to the IP interface named

System

and the

z

represents

the corresponding number of subnets in CIDR notation.

The IP interface named

System

on the switch can be assigned an IP address and subnet mask

which can then be used to connect a management station to the switch’s Telnet or Web-based

management agent.

The system message

Success

indicates that the command was executed successfully. The

switch can now be configured and managed via Telnet and the CLI or via the Web-based

management agent using the above IP address to connect to the switch.
