hexadecimal characters, sometimes with colon or dash separators
between every two characters, such as “00:03:d3:00:00:17” or
“00-03-d3-00-00-17”.
explorer view
The tree view within the Connection Expert window that shows all
devices connected to a test system.
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 an instrument 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.
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.
