Hardware Diagnostic Tests
Testing Switch-to-Device Network Communications
You can perform the following communication tests to verify the network is
operating correctly between the switch 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 switch console interface from a
terminal connected to the switch or through a telnet connection. See the
Management and Configuration Guide that is on the documentation
CD-ROM that came with your switch for more information.
These tests can also be performed from an SNMP network management
station running a program that can manage the switch, for example, ProCurve
Manager or ProCurve Manager Plus.
Testing End-to-End Network Communications
Both the switch and the cabling can be tested by running an end-to-end
communications test -- a test that sends known data from one network device
to another through the switch. 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 switch, you can use this test to verify the entire
communication path between the two PCs is functioning correctly. See your
LAN adapter documentation for more information on running a link test or
Ping test.
