Flowchart 4 Procedures

Checks communications between transport layers on the source and

target host using telnet and ftp sessions.

• Execute a ping from aknown good hostthrough a gateway to another

known good host. This will test connectivity through bridge/gateway

level. If successful, execute netstat(1M) -r command and examine

the route table. If the gateway is an HP9000, execute the ifconﬁg for

all interfaces on gateway. Continue to the Network Level Test.

• If the ping is not successful, examine whther the gateway is HP or

non-HP system. If it is non-HP, refer to the networking

documentation for that product. If the gateway is an HP system,

execute the ifconﬁg for all interfaces on gateway or host. (See

Conﬁguration Tests for more details on ifconﬁg)

•Ififconﬁg does not show the parameter as UP in the output for the

gateway, then execute netstat(1M) -i to check the status of the

network interfaces. An asterisk (*) indicates the interface is down. If

the network interface is down, conﬁgure the interface UP and

continue to the Network Test. If all interfaces are UP, go the

Conﬁguration Tests and test all interfaces on the gateway.

Flowchart 5: Conﬁguration Tests

Veriﬁes the conﬁguration of the network interface on a host using the

lanscan(1M), ioscan, netfmt(1M), lanadmin(1M), and ifconfig(1M)

commands.
