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...
