Installing and Configuring 10/100Base-TX/9000
Known Problems and Workaroundsa switch, that is autonegotiating, the HP-PB card will autonegotiate with the device to mutually determine the highest possible speed and duplex settings between them.
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 WorkaroundsIf 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 -Xmode ppa (nmid) command as explained in “Manual Speed and Duplex Mode Configuration” in this Release 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).
