End-to-End Network Tests

If your PC LAN adapters (or end nodes) support network communication
tests, you can perform these tests through the HP 100VG hub to help isolate
network problems. Refer to your LAN adapter documentation for more
information on available network communication tests.

Communication tests through the hub can be performed between two 100VG
LAN end nodes equipped with 100VG LAN adapters. If the HP 100VG hub
contains a bridge module, you can perform communications tests between
an Ethernet/IEEE 802.3 LAN end node and a 100VG LAN end node.
