146 Glossary
G
gateway
Hardware that permits a network connection between the LAN that your
computer understands and the instrument specific interface that your
device understands.
Gateway IP Address
This parameter is the IP Address of the default subnet gateway that
allows the E5810 to communicate with systems that are not on the local
subnet. Thus, this is the default subnet gateway where packets are sent
that are destined for a device not on the local subnet, as determined by
the subnet mask setting. Only one default subnet gateway can be
configured. A value of 0.0.0.0 indicates that no subnetting is to be done.
H
Hostname
This parameter is the Internet domain name for the E5810. Depending
upon the type of servers in the network, you may be able to use this
name to communicate with the E5810. However, since you can always
use the IP Address or the name supplied by another name server, the
Hostname is not a required configuration value.
You may enter up to 15 characters for the Hostname. The Hostname
must start with a letter and consists of upper and lower case letters and
digits and dashes. The default Hostname is “E5810-” plus the last four
characters of the Ethernet (MAC) address, such as E5810-e40c.
hub
A common connection point for devices in a network. Hubs are
commonly used to connect segments of a LAN. A hub contains multiple
ports. When a packet arrives at one port, it is copied to the other ports so
that all segments of the LAN can see all packets.
- Passive hubs serve simply as a conduit for the data, enabling it to go
from one device (or segment) to another.
- Intelligent hubs include additional features that enables an administrator
to monitor the traffic passing through the hub and to configure each port
in the hub. Intelligent hubs are also called manageable hubs.
- Switching hubs actually read the destination address of each packet
and then forward the packet to the correct port.
