D-Link DES-3250TG Standalone Layer 2 Switch
 
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 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: 
IP Address 
Determines the IP address used by the switch 
for receiving SNMP and Telnet 
communications. These fields should be of the 
form xxx.xxx.xxx.xxx, where each xxx is a 
number (represented in decimal) between 0 and 
255. This address should be a unique address 
on a network assigned to you by the central 
Internet authorities.  
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 (a computer) will 
be allowed to manage the switch using TCP/IP 
(in-band, or over the network). 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 Management 
Station IP Addresses field. The default VLAN 
is named default and contains all of the
