Other possible causes of a fault condition could be:
• A defective cable
• A cable not connected to an active hub or switch
• A defective card
HP-UX Manual Reference Pages (manpages)
While installing, configuring, or troubleshooting Ethernet, you may need to refer to any
of the following online manual reference pages (manpages) for useful HP-UX operating
system or Ethernet commands. To display a manpage, enter the following at the system
prompt: man command name. For example, man arp.
• arp(1M) displays and modifies the Internet-to-station address mapping tables used
by the Address Resolution Protocol.
• hosts(4) is a database that contains a single line entry for each host name entry.
• ifconfig(1M) assigns an address to a network interface and configures and displays
network parameters.
• ioscan(1M) scans system hardware, usable I/O system devices, or kernel I/O system
data structures as appropriate, and lists the results.
• lanadmin(1M) resets or reports the status of the La card. Also used for configuring
virtual LANs (VLANs), setting TCP Segmentation Offload (TSO) on or off, and
getting 64-bit MIB statistics.
• lanscan(1M) displays information about La cards that are successfully bound to the
system.
• linkloop(1M) verifies network connectivity through the Data Link Layer (OSI
Layer 2).
• netfmt(1M) formats common tracing and logging binary files.
• netstat(1) provides network statistics and information about network connections.
• nettl(1M) logs network events and traces packets as they enter and exit the
Ethernet driver.
• ping(1M) verifies network connectivity through the Network Layer (OSI Layer 3)
and reports the round-trip time of communications between the local and remote
hosts.
• rad(1M) in HP-UX 11i performs OL* functions without any comprehensive checks.
• route(1M) adds and deletes entries to the network routing table.
• sam(1M) configures the networking software.
• swinstall(1M) loads software filesets.
• swverify(1M) verifies the software installation.
• swlist(1M) verifies the driver software installation.
• vlan(1M) provides over of managing virtual LANs (VLANs).
