Duplex setting in HP Unix :-
( To see the PPA number of the LAN card )
# lanadmin -x PPA_no ( Here X - small letter : for view the setting)
i.e Ex: # lanadmin -x 0
( Assuming 0 is PPA number )
If you want to set the speed then run the below command
#lanadmin -X (100HD|100FD) <NMID>
To get the NMID use lanscan command.
