LevelOne GSW-1290 Gigabit Layer2 SNMP Switch
To manually assign the Switch’s IP address, subnet mask, and default gateway address:
1. Select Manual from the Get IP From drop-down menu.
2. 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.
VID This allows the entry of a VLAN ID 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
