The Link Test is a test of the link layer (MAC Address) connection between a
local device and a designated remote device. During the Link Test, an IEEE
802.3 test packets are sent from the local device to the remote device. The
remote device returns the data to the local device, where it is compared to the
data transmitted. If the received data matches the transmitted data, the test
passes. The remote device must be able to recognize an IEEE 802.2 test packet
to be able to respond.
The Link Test is useful because it can tell you whether the hub you are
managing is communicating properly with another device.
The Link Test Window in the Browser Interface displays the following
graphical objects:
Status Bar. Displays varying portions of the bar in green (at the left
section of the bar) and red (at the right section of the bar). The amount
of both green and red area is a proportional representation of how many
successful and failed tests have been reported in the current session. If
the bar is mostly red, you may want to check for connection problems.
Destination IP/MAC Address. Indicates the network address (for the
Ping Test) or the MAC address (for the Link Test) of the device to which
you want to test a connection with the current device.
