D-Link DES-3550 Инструкция по эксплуатации онлайн [42/260] 40392
DES-3550 Fast Ethernet Layer 2 Switch
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.
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 allows 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.
Auto Config State
When autoconfig is enabled, the Switch is instructed to get a configuration file via TFTP,
and it becomes a DHCP client automatically. The configuration file will be loaded upon
booting up. In order to use Auto Config, the DHCP server must be set up to deliver the
TFTP server IP address and configuration file name information in the DHCP reply
packet. The TFTP server must be running and have the requested configuration file
stored in its base directory when the request is received from the Switch. Consult the
DHCP server and/or TFTP server software instructions for information on loading a
configuration file for use by a client. (Also see the section titled Upload Configuration for
instructions on uploading a configuration to a TFTP server.
If the Switch is unable to complete the autoconfiguration process the previously saved
configuration file present in Switch memory will be loaded.
Click Apply to let your changes take effect.
