Hi, the ports themselves don't have an IP address. The switch has one IP address for online configuration. this model does switching only and doesn't use DHCP to issue addresses

Change ip address


You cannot change the ip address, if you are using static ip address.If it is dynamic ip address, you can change it easily by resetting the modem or switching it off and on.you can also use Proxy server or Hide ip address software to change the ip address.

To check the ip address before and after changing, Visit the site ip-details.com Here you can also search IP,domain host and it also includes city, country, global latitude & longitude coordinates etc.

What do you need it configured to support? Multiple subnets? VoIP support?
Here's an example to support 2 subnets, VLAN 1 Data and VLAN 2 Voice. This switch is the VLAN router for the site and it is also the default gateway for all the devices on the network.

I'm not too familiar with Netgear switches, but if you told me you were having this issue with a Cisco switch, I'd tell you that after you change the IP address you need to save your configuration to NVRAM using the "copy run start" command. A Cisco switch will look to start using the configuration stored in NVRAM when it is booted. Changes are made to the configuration in RAM and are lost when reboot occurs unless they are first saved to NVRAM. Perhaps there is a similar command for the Netgear switch. Hope this helps

How to configure d-link switch


Hi there, there is no real configuration settings for switchs as they are generally considered "Unmanaged Devices" and have no managment interface, if your using this device to connect 2 or more computers, then you need to assign ip's on each computer statically..
the general procedure for this is as follows. in Windows XP, right click on My Network (might be called network neighborhood) , click propertys, it should pop up a window with a list of items, one of them should be "TCP/IP", click on that and click Properties, in the new window, click "Use The following ip address".
on Computer A, you want to use the following settings.
IP Address: 192.168.1.5 subnet mask : 255.255.255.0 Default Gateway: 192.168.1.1 (or the ip address of your router)
Click "Use the following DNS Server addresses"
Preferred DNS Server: 4.2.2.1 Alternate DNS Server : 4.2.2.2
click ok, and do the same procedure on the 2nd and 3rd computers, in the ip address box on computer 2 and 3, add 1 to the final number, so computer B would have an ip of 192.168.1.6 Computer 3 would have 192.168.1.7 , and so on.

Unable to get IP address


The D-link DSS switch should require nothing special to pass along IP addresses. You may want to power off your computer, switch and router, and then power up after 30 seconds. It could be that when you were testing, the computer pulled an IP address from the router and if you moved to the switch without renewing the IP, there was a conflict. Powering down and repowering should do the trick.

Here's what you need to do:

First, be sure to assign an ip address(in the proper subnet) to each VLAN.

Second, use the ip helper-address command in the context of each VLAN, the address used should be the address of the DHCP server

Third, Add a scope for each additional VLAN on the DHCP server.

The switch will route the DHCP request to the proper server based on the ip helper-address command parameter and based on the ip address of the VLAN that is passed tot he server, a DHCP address in the proper subnet is automatically configured.

Here is a sample:

ProCurve Switch 3500yl-24G-PWR# configure
ProCurve Switch 3500yl-24G-PWR(config)# vlan 33
ProCurve Switch 3500yl-24G-PWR (vlan-33)#ip address 192.168.33.254/24
ProCurve Switch 3500yl-24G-PWR (vlan-33)# ip helper-address 10.1.2.250

At-8624t


How to Configure the Switch
Some configuration is necessary to enable the switch’s advanced switching
capabilities. This is achieved via the Command Line Interface (CLI). On the
AT-8624T/2M, you can also use the Graphical User Interface (GUI).
Using the CLI to configure a switch
1. Connect a terminal or PC to the Terminal Port (ASYN0).
Using the supplied RS-232 DB9 serial straight-through cable, connect your
terminal or PC to the RS-232 Terminal Port:
• For the AT-8624T/2M and AT-8624PoE, the RS-232 Terminal Port is on
the front panel.
• For the AT-8648T/2SP, the RS-232 Terminal Port is on the back panel.
2. Set the communication parameters.
Set the communication parameters on your terminal or terminal emulation
program to:
• Bit rate: 9600
• Data bits: 8
• Parity: None
• Stop bits: 1
• Flow control: None
3. Log in.
After the switch has booted, the login prompt appears. If the login prompt
does not appear, press [Enter] two or three times.
When the switch boots for the first time it automatically creates an
account with manager privileges. The account has the login name manager
and the password is friend.
At the login prompt, enter the login name and password:
Login: manager
Password: friend
The switch’s command prompt appears. Now use the CLI to configure the
switch.
Using the GUI to configure the AT-8624T/2M switch
This section describes how to establish a connection to the AT-8624T/2M switch
through the GUI so you can configure it before installing it in your LAN.
1. Select a PC to use and identify its subnet.
You can browse to the switch from any PC that is running a supported
operating system with a supported browser installed. JavaScript must be
enabled. If you are using a toolbar or plug-in on your browser to block popups,
disable it while using the GUI. The GUI displays detailed configuration
options and information in pop-up windows.
2. Connect the PC to the switch.
Use an Ethernet cable to connect an Ethernet card on the PC to any one of
the switch ports.
You can browse to the router through any VLAN, as long as you give that
VLAN an IP address. These instructions assume you are using vlan1. All
switch ports belong to vlan1 by default.
3. Access the switch’s command line interface.
Access the CLI from the PC, as described in the previous section, “Using
the CLI to configure a switch”.
Installation & Safety Guide 13
4. Enable IP.
enable ip
5. Assign the vlan1 interface an IP address in the same subnet as the
PC.
add ip interface=vlan1 ip=ipaddress mask=mask
6. Save the configuration and set the switch to use it on bootup.
create config=your-name.cfg
set config=your-name.cfg
7. On the PC’s web browser, bypass the HTTP proxy server, if
necessary.
8. Point your web browser at IP address for vlan1.
9. At the login prompt, enter the user name and password.
User Name: manager <the default>
Password: friend
The System Status page is displayed. Select options from the sidebar menu
to configure and manage the switch.
For context-sensitive online help, click the Help button at the top of the
sidebar menu or on any pop-up page


I hope this helps you out
