How to check/set Half duplex / Full duplex for LAN card?

Duplex setting in HP Unix :-

# lanscan
( 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)

To get the NMID use lanscan command.
