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
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 Routing tables Dest/Netmask Gateway Flags Refs Interface Pmtu 127.0.0.1/255.255.255.255 127.0.0.1 UH 0 lo0 4136 22.214.171.124/255.255.255.255 126.96.36.199 UH 0 lan0 4136 188.8.131.52/255.255.255.255 184.108.40.206 UH 0 lan1 4136 220.127.116.11/255.255.252.0 18.104.22.168 U 2 lan0 1500 22.214.171.124/255.255.248.0 126.96.36.199 U 2 lan1 1500 127.0.0.0/255.0.0.0 127.0.0.1 U 0 lo0 4136 default/0.0.0.0 188.8.131.52 UG 0 lan0 1500
Look at the interface column to get
lanX number. For example, we will try to get the MAC of
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
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 LOCAL AREA NETWORK ONLINE ADMINISTRATION, Version 1.0 Mon, Apr 17,2017 18:10:09 Copyright 1994 Hewlett Packard Company. All rights are reserved. 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
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 LAN INTERFACE STATUS DISPLAY Mon, Apr 17,2017 18:10:26 PPA Number = 1 Description = lan1 HP PCI-X 1000Base-T Release PHNE_36237 B.11.11.15 Type (value) = ethernet-csmacd(6) MTU Size = 1500 Speed = 1000000000 Station Address = 0x1a3b08c4a1 Administration Status (value) = up(1) Operation Status (value) = up(1) Last Change = 185 Inbound Octets = 1362884960 Inbound Unicast Packets = 1309204600 ----- output clipped -----
Here you can pad two zeros in from of station address to make it perfect 12 alphanumeric MAC. Means
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.
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.
