100Base-T Checklist
Chapter 5 53
- Patch(es) for lanadmin - current lanadmin provides the
lanadmin -x -X functionality.
- Patch(es) for SAM - all systems need an updated SAM patch because SAM can “step on”
the 100Base-T configuration file Duplex mode.
• Display the card’s current speed and duplex, issue the command:
lanadmin -x NMID/PPA (nmid/ppa comes from the lanscan command)
Or,
nwmgr -g -A speed -c lanPPA
• If problems persist, if a switch is used, manually set the switch port to the desired speed
and duplex.
• Manually set the card to the desired speed:
- for 100Base-T hubs: 100 Half Duplex
- for 10Base-T hubs: 10 Half Duplex
• Manual setting can be done temporarily with the command:
lanadmin -X speed/duplex nmid/ppa
Or,
nwmgr -s -A speed=SPEED -c lanPPA
You may check the allowed speed with the manual, depending on each interface type
• Manual setting can be permanently set by modifying the configuration file in
/etc/rc.config.d or by using SAM (recommended way).
• If problems persist: connect the card to a switch or hub that is known to be good.
• If this connection works, contact the HP Response Center with the Switch/Hub
information. This may be an IOP (Interoperability) problem.
• If this connection fails, the card may be bad and may need to be replaced.
