I have two btlan cards on the same subnet
and carried out the following:
#ifconfig lan1 ip_addr netmask_addr up
#ifconfig lan5 ip_addr netmaks_addr up
#lanadmin -x 1
Current Config = 100 Full-Duplex AUTONEG
# lanadmin -x 100FD 5
btlan: ERROR: Setting 100FD is unsupported
Current Config = NO LINK AUTONEG
I am having problems with modifying the second card to 100 Full duplex
Is this due to both cards on the same subnet is there are work around?
Solved! Go to Solution.

Re: two cards on same subnet
(With "ndd -set /dev/ip ip_strong_es_model 1" you can make it work somewhat, but having two NICs simultaneously active on the same network segment without APA is an unsupported configuration and is not recommended.)
With APA you can get both cards active together. ServiceGuard can use APA if both are installed on the same server.
With just ServiceGuard only one of the cards can be active at a time. If it fails, SG will switch the traffic (and the IP addresses) to another card.
Without knowing the hardware type of your NICs and your HP-UX version & Quality Pack level, it's hard to guess what might be wrong.
The output of commands "ioscan -fnkClan" and "lanscan -v" would be very informative. If one of the cards is built-in to the system board of your server, the output of "model" command might be useful too.

Re: two cards on same subnet
lanadmin -X 100FD 5
if it does not work please check the cable (linkloop.)

Re: two cards on same subnet
use lanscan to find out the mac adress
to check the cable in lan 5
linkloop -i [mac of lan5] 5
to check the cable in lan 1
linkloop -i [mac of lan1] 1
to check if lan 1 and 5 are in the same vlan.
linkloop -i [mac of lan1] 5

Re: two cards on same subnet
Could you provide the lan5 card details?
Is this card supports Full duplex?
Look at the errors.

Re: two cards on same subnet
#lanadmin -X 100DF 5
You should be set with that, If not check for a couple of things
1) Cabling
2) Duplex setting on your switch
3) You NIC card spec's
Like it or worked !! Click kudos !!

Re: two cards on same subnet
In early versions of 11.11 this plan was strictly forbidden. I tried it once and both NIC cards dropped of the network instantly.
Later releases of 11.11 supposedly supported it.
I think you need APA, Auto Port Aggregation to get any real benefit of increased band width out of this configuration. That is the tool designed to do the job.
