Different ways to find the MAC address of LAN card in HPUX. Learn how to use lanscan, lanadmin, print_manifest, SAM to check MAC.
MAC addresses also known as station addresses can be found physically on LAN cards which are mostly PCI cards on your HP server. Obviously being hardware, it’s not always feasible to open up just to get MAC address! Another way is to get these details from the OS command. You can use lanscan, lanadmin, sam, print_manifest command to get the MAC address of the LAN card in HPUX.
First, you need to get a LAN number on which your expected IP is configured. You can use netstat -nvr to check all IP configured on the system and their respective LAN number.
# netstat -nvr

12.125.96.0/255.255.248.0 12.125.101.123 U 2 lan1 1500
127.0.0.0/255.0.0.0 127.0.0.1 U 0 lo0 4136
default/0.0.0.0 12.123.51.1 UG 0 lan0 1500
Look at the interface column to get lanX number. For example, we will try to get the MAC of lan1 interface.
lanscan command
lanscan command without any argument will give you station address i.e. MAC addresses of all available LAN on the system.
# /usr/sbin/lanscan
Hardware Station Crd Hdw Net-Interface NM MAC HP-DLPI DLPI
Path Address In# State NamePPA ID Type Support Mjr#
0/1/2/0 0x001A3B08C4A0 0 UP lan0 snap0 1 ETHER Yes 119
0/1/2/1 0x001A3B08C4A1 1 UP lan1 snap1 2 ETHER Yes 119
Look station address and column and check the value against lan1! lan1 has MAC of 0x001A3B08C4A1.
lanadmin command
This is not straight forward as lanscan command. After issuing lanadmin command you will be presented with lanadmin console prompt where you can use lanadmin commands. Example below.
# /usr/sbin/lanadmin

Test Selection mode.
lan = LAN Interface Administration
menu = Display this menu
quit = Terminate the Administration
terse = Do not display command menu
verbose = Display command menu
Enter command: lan
Here type command lan. You will be greeted with the LAN interface mode prompt like below.
LAN Interface test mode. LAN Interface PPA Number = 0
clear = Clear statistics registers
display = Display LAN Interface status and statistics registers
end = End LAN Interface Administration, return to Test Selection
menu = Display this menu
ppa = PPA Number of the LAN Interface
quit = Terminate the Administration, return to shell
reset = Reset LAN Interface to execute its selftest
specific = Go to Driver specific menu
Enter command: ppa
Enter command ppa and change your number to 1 since we are checking lan1 in our example. Default is set to lan0
Enter command: ppa
Enter PPA Number. Currently 0: 1
LAN Interface test mode. LAN Interface PPA Number = 1
Once LAN interface PPA changed to 1 hit command display and you will be shown all details of that lan card including station address!
Enter command: display

Here you can pad two zeros in from of station address to make it perfect 12 alphanumeric MAC. Means 1a3b08c4a1 becomes 001a3b08c4a1.
Using SAM
You can even use SAM (text based GUI tool) to get these details. Go to,
SAM -> Networking and communications -> Network Interface Cards
Select your lan (in our case lan1) using a space bar (it will be highlighted). Then choose Actions from the menu bar to get details.
Using print_manifest
If you have Ignite installed on the server then you can try print_manifest command to get all system details. Those details also include MAC of all lan cards. The only issue is your LAN PPA number won’t be available here in output to match MAC with lan id.
