DGS-3312SR Stackable Gigabit Layer 3 Switch
39
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 ID (VID) 1. 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 ID 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 VID 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
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 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.
