192.0.0.* segment

CSP_ALGERIA — Wed, 11 Feb 2004 05:31:17 GMT

hello

we have L3000 server running under HPUX 11.i.
we have 06 lan card lan0 lan1 and lan2
and the customer is using 192.0.0.* segment.
we give lan0 ipaddress 192.0.0.16 and it work normaly .But when we try to give for

lan1 192.0.0.x and lan2 192.0.0.y it doesn't work and we have an error message from SAM , that we cann't give the ipaddr 192.0.0.* for those cards.

is there a solution for this , or we should change this segment to 192.50.0.* for example with is verry hard for the customer.

thanks

Best regards

Try,

ifconfig lan1 plumb
ifconfig lan1 up
ifconfig lan1 192.0.0.x netmask 255.x.x.x up

Because of the limited support, HP does not recommend configuring multiple LAN cards on the same IP subnet.

Hi,

In addition to the previouse answers.
Why do you need multiple interfaces in the same subnet ( Load balancing/ redundancy )? Mind your routing table. ( one default gateway). I would suggest installing APA. This software enables both previously mentioned reasons. This is software that needs to be purchuached and supported on the switch connected to the server asswell.

HTH,

Hi,

Though it is not officially supported,in 11i this will work but there are set of guidelines on the networking behaviour from HP when there are multiple lan cards in the same subnet.

This is not recommended. I would go with multiple subnets or APA as mentioned above
