DES-3550 Fast Ethernet Layer 2 Switch
3. If you want to access the Switch from a different subnet from the one it is installed on, enter the IP address of the
Default 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.
4. If no VLANs have been previously configured on the Switch, you can use the default VLAN Name. 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.
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 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 IP Address 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 pro-
tocol 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.
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 gate-
way. 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 here 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 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 a
management VLAN is specified or Management Station IP Addresses are assigned.
Admin State
This field will allow the user the enable or disable the Admin State for the IP interface, by
the using the pull-down menu. Disabling this feature will render all remote management
inoperable, and thus the only way to configure the Switch will be to use the Console port for
the Command Line Interface.
