LAN cards

[S Keane]

Simple enough query really. If you have more than one LAN card on a 9000/700 or 9000/800 platform, how can you tell which is the built in LAN. The ouput of ioscan sometimes tells you in the description field, but not always.
I would like to determine via software, as the hardware may be at a remote site. This is for HP-UX 10.20 and HP-UX 11.00.

Must be different types of HW. Everytime I do the ioscan -fnClan the description will tell me it is a built-in.

Another method is to check the driver. Built-in NIC cards have a driver that is typically a lan2 driver. Add-on cards use btlanX drivers.

while it is true that many interfaces driven by the lan2 driver are "built-in" it is indeed possible for an add-on card (eisa) to be driven by the lan2 driver.

also, newer systems have a 10/100 interface that is driven by the btlan3 driver, some the btlan6 driver, and the btlan6 or btlan5 driver could be an add-on card.

finally, some systems do not have a "core" lan - just a bunch of PCI slots, one of which can have a lan card - eg the V Class.
