I've never used switch, but I thought ethtool could tell you the status of the connection to the switch. How about comparing these results when things are working well and when things go wrong? 1. # ethtool eth0 2. # ethtool --test eth0 3. # ethtool --test eth0 external_lb Here, 3. includes a test for external loopback, but I don't know if this test is meaningful or not.
