Installing and Configuring 10/100Base-TX/9000
Known Problems and Workarounds
a switch, that is autonegotiating,the HP-PB card will autonegotiatewith
the device to mutually determine the highest possible speed and duplex
settings between them.
NOTE If the HP-PB 10/100Base-TX/9000 card is connected to a device that
does not support autonegotiation or a device that has autonegotiation
disabled, the HP-PB card will autosense the speed of the link and set
itself accordingly. The duplex mode of the card will be set to
half-duplex in this case. If you want the card to operate in full-duplex
mode, you have to set it using the method described in “Manual Speed
and Duplex Mode Configuration.”
The HP-PB 10/100Base-TX card will sense when the connection between
itself and a hub or switch on the other end of a link has been broken. If a
connection is made to another (or the same) device, the autonegotiation
and autosensing process will be done again automatically.
Autonegotiation and autosensing are also done whenever the interface is
reset.
Known Problems and Workarounds
If your switch supports autonegotiation, you should not normally need to
set the duplex mode or the speed of the HP-PB 10/100Base-TX card.
Optionally, you can set the full- or half-duplex mode of the card by using
the lanadmin -X
mode ppa
(
nmid)
command as explained in “Manual
Speed and Duplex Mode Configuration” in this Release Note.
NOTE You cannot set the mode of the card in SAM (the field in SAM that
contains the setting for full-duplex is ignored--it may show the MAC
address of the card but cannot be used for configuration).
