BOOTP or DHCP protocols to assign the Switch an IP address, subnet mask, and default
gateway address:
Use the
Get IP From: <Manual>
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 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 that 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.
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.
