This works well in most cases. If NFS client and server are both capable to use jumbo frames, perfect! But clients with different adapters and standard MTUs can't access files on an NFS server if the latter one uses jumbo frames. Thus possible NFS problems should be mentioned in the man page. >How-To-Repeat: Try to setup client and server as explained above. >Fix: *** bge.4 Thu Apr 10 11:15:47 2003 --- bge.4.new Thu Apr 10 11:18:32 2003 *************** *** 89,95 **** .Xr ifconfig 8 utility configures the adapter to receive and transmit jumbo frames.
