Flowchart 5 Procedures
• Execute ping(1M) from a known good host through a gateway to another known
good host. This will test connectivity through bridge/gateway level. If successful,
execute netstat -r and examine route table on problem host and all hosts in path.
If necessary, correct routing table and go to Network Level Tests.
• If ping fails, examine gateway to see if HP 9000 or non-HP. If non-HP, refer to
networking documentation for that product. If HP 9000, execute ifconfig(1M) for
all interfaces on gateway or host (see Configuration Tests for more details on
ifconfig).
• If ifconfig does not show parameter as UP in output for gateway, execute netstat -i
to check status of network interfaces. An asterisk (*) indicates interface is down. If
network interface is down, configure interface up and repeat Bridge/Gateway Test. If
all interfaces are up, continue to Configuration Tests and test all interfaces on
gateway.
