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 -rand 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 -ito 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.
