Operational state of lan in HP-UX 11 without using lanadmin?

[Christian Ching]

Hi,

Is there a way of discovering the operational state of a lan card without using lanadmin? It was possible to achieve this using lanscan in 10.20, but lanscan has changed in 11.

Thanks!

When I issue Lanscan I get this:-

lanscan
Hardware Station Crd Hdw Net-Interface NM MAC HP-DLPI DLPI
Path Address In# State NamePPA ID Type Support Mjr#
10/12/6 0x080009AD0423 0 UP lan0 snap0 1 ETHER Yes 119

Which is the same as in 10.20 and it tells me the state of the lan card. Is this what your after?

Hi,
from what I understand, there are three states, software, hardware and operational. The operational state determines whether the network is working correctly, so it should show 'UP' when, say the network cable is plugged in, and 'DOWN' when it is unplugged. This works in lanadmin, and lanscan in 10.20, but I'd like to have an alternative to lanadmin, or a command line which shows that information.

Thanks,

Christian

Hi,

Try command: netstat.
see the manual pages.

Thanks,
I have already tried this using
netstat -I lan0 ,
but somehow this gives inconsistent results, and takes a long time before it shows the operational state is down. It will come up with lan0* but it doesn't always seem to do this. My problem is that I currently have issues using lanadmin which are waiting to be addressed, and in the meantime would like something that can be used in a script and show the operational state, so netstat wouldn't be appropriate as it takes too long, say if I have a lot of lan cards on the system.

Thanks!

Hello Christian,

you could ask the local SNMP agent (snmpdm) to tell
you about that. Get some "snmpget" or "snmpwalk"
commands from the internet (UCD, perhaps) and have
a look on the MIB variables below
.iso.org.dod.internet.mgmt.mib2.interfaces
There you will find "adminStatus" and "operStatus" for
each interface you have and you do not have to be
"root" to run those commands.
HTH,

Hi :
Please try this script, hope this can help.

ldw@hputaiv$ cat lanstat.cmd
#! /usr/bin/sh
/usr/bin/uname -a
/usr/sbin/lanscan
ppas="0 1"
for ppa in $ppas
do
stat=`/usr/sbin/lanadmin 2>/dev/null <l
ppa $ppa
d
q

EOF
`
echo $ppa --- $stat
done

Here is sample output :
ldw@hputaiv$ ./lanstat.cmd

0 --- Operation Status (value) = up(1)
1 --- Operation Status (value) = up(1)

How about "ifconfig interface name",I'd do a lanscan to find the number of lan interfaces on the system and then ifconfig to get the interface state.

[Robert Landstrum]

lanscan will show you the software state, if the card is configured. ifconfig will show you the hardware state, if the card is UP, ifcongig will show you. If the the card is not up, ifconfig will not show you a DOWN, it will just not show UP.

Thanks for the help, especially Wodisch and Dyi-Wu. I think its very easy to get confused between hardware, software and operational state!!
