HPUX : HOW TO SET THE LAN WITH 100FD SPEED

 lan0 and lan5 configured  for the server and backup is failing because of multiple frame collisions on lan0

Late collision is oberserved on the server which is high on the interfaces. Below point can be check.
1. Check and or replace the network cables (may be damaged, loose, etc.)
2. Check and or replace the NIC ( temporarily replace with another NIC known to be good)
3. Check all hubs for serviceability. (swap ports around to isolate the bad ones)

If was found on the server that interface are running on half-duplex speed and Network team confirm the swtich port is set at
100FD.
Recommeddatoin : Setting the lna0 and lan5 at 100FD will resolve the problem, as speed setting of devices is uncompatabiable.
