• Enter ping(1M) 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 go to Network Level Tests
(Figure 4-3).
•Ifping 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(1M) for all
interfaces on gateway or host (see Configuration Tests, Figure 4-9, for more details
on ifconfig).
• If ifconfig does not show the UP parameter as output for the gateway, enter netstat
-i to check the status of network interfaces. An asterisk (*) indicates that the
interface is down. If the network interface is down, configure the interface up and
repeat the Bridge/Gateway Test (Flowchart 7). If all interfaces are up, continue to
the Configuration Tests (Flowchart 8) and test all interfaces on the gateway.
