Hi Martin,
Thanks for your reply,Yes I tried swapping the assignments,same thing is
happening in both cases..ifconfig and route -n results are as below:

RE: enabling two eths
Send the results of
ifconfig
and
route -n
I take it eth0 works fine...
Have you tried swapping the assignments and see if eth1 works (to
eliminate faulty hardware).

Hi, Thanks for your kind reply, Yes i have used different * IP Subnets*
The IPs and subnet details I use is
1. eth0(configured through u-boot env settings)->> 192.168.174.231 and
subnet is 255.255.255.0
2. eth1(configured after kernel is up)--> 192.168.33.64 and subnet is
255.255.248.0
Even i tried by connecting second eth to host PC using cross cable as a
stand-alone network but even "ping" did not work..
Thanks & Regards

It depends :)
I used to test functionality such a way to have two enets in same subnet,
then ifdown one of them.
At least with mvista RFS, one enet handles NFS, other is up but all the
packets are routed to it via
the first one. And when the first one got ifdown, routing switches to the
remaining enet...
