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..

Hi,

We are using MPC8272 based target board, we use montavista Linux

2.6.10 kernel image (with NFS enabled) to our target board,

one after the kernel is up using linux command  "ifconfig eth1

Please suggest how to enable second eth (either 0 or 1) once the

Have you made sure that eth0 and eth1 are on *different* IP subnets?
If they are on the same subnet, or intersecting subnets, your routing
will get confused.

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...
