NFS problem- neighbout table overlow

NFS problem- neighbout table overlow

[Navin Boppuri]

Hello Everyone,

I have been having problems with my custom board. The NFS mount does not
work. The NFS request does not actually go the server. I dont see any
packets coming to the server from this board. I did have some ring dump
problems. There were some errors in Port A setting which I fixed and that is
gone now. By I still see 'neighbour table overflow' messages. What can be
the problem?

Navin,
I can't say that I remember for sure - but I seem to recall
this as being a problem in the Linux NFS implementation.
Check through the linux-kernel archives for messages regarding
the neighbour table overflow.  There may be a suggestion
on how to solve this.  I know I remember something about this...

When you see the "neighbour table overflow" message it simply means that
NFS cannot communicate with the server.  It could mean anything from a
bad cable, invalid IP setup, bad driver, incorrect driver setup, etc.
It really means that you are not successfully transporting IP packets.

Hello everyone,

Thank you for all the help. All I needed to do was to change the setting of
SICR_ENET_CLKRT defined in commproc.h . The SCC2 was not configured
correctly. jonb@marel.is  pointed this out to me. The ethernet now works
just fine.

Navin.
