4.3.8.1 Flowchart 7 procedures
• Enter ping from a known good host through a gateway to another known good host. This
will test connectivity through the bridge/gateway level. If successful, run netstat -r and
examine the route table on the problem host and all hosts in the path. If necessary, correct
the routing table and perform the network-level tests (“Flowchart 3: Network-level tests”
(page 43)).
• If ping fails, examine the gateway to see if it is an HP or non-HP product. If non-HP, see
networking documentation for that product. If HP, enter ifconfig for all interfaces on gateway
