HP J3175A, J3177A manual Testing End-to-End Network Communications

Troubleshooting

Diagnostic Tests

	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 HP LAN adapters, you can use the “Link Test” option from
	the adapter’s test program (for example, HPLANSet) to verify that the entire
	communication path between the two PCs is functioning correctly. See your
	LAN adapter documentation for more information on running the Link Test.
N o t e	Link Test can be performed from end node to end node through the switch
	even if the switch does not have a Switch Management Module installed. But,
	with the module, the switch itself cannot respond to any network connectivity
	tests (link test, Ping test, or IPX Ping test).
	Testing Switch-to-Device Network Communications
	If you have a Switch Management Module installed in the switch, you can
	perform the following communication tests to verify that 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
	■ IPX Ping Test -- a network layer test used on IPX networks that sends test
	packets to any device identified by its IPX address
	These tests can be performed through the switch console interface from a
	terminal connected to the Switch Management Module. See the
	HP AdvanceStack Switch 208/224 Management Module Installation and
	Reference Guide 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, HP
	AdvanceStack Assistant.
