Testing Hub-to-Device Network Communications (Hub
12M and Hub 24M only)
You can perform the following communication tests to verify that the network
is operating correctly between the Hub 12M or Hub 24M and any connected
device that can respond correctly to the communication test.
■
Link Test -- a physical layer test that sends IEEE 802.2 test packets to any
device identified by its MAC address
■
Ping Test -- a network layer test used on IP networks that sends test
packets to any device identified by its IP address
These tests can be performed through the hub console interface from a
terminal connected to the hub or through a telnet connection, or from the
hub’s web browser interface. See the
Management and Configuration Guide
that came with your hub for more information.
These tests can also be performed from an SNMP network management
station running a program that can manage the hub, for example, HP TopTools
for Hubs & Switches.
Testing End-to-End Network Communications
Both the hub and the cabling can be tested by running an end-to-end commu-
nications test -- a test that sends known data from one network device to
another through the hub. For example, if you have two PCs on the network
that have LAN adapters between which you can run a link-level test or Ping
test through the hub, you can use this test to verify that the entire communi-
cation path between the two PCs is functioning correctly. See your LAN
adapter (NIC) documentation for more information on running a link test or
Ping test.
