In article <8809211412.AA08336@ucbvax.Berkeley.EDU> KASTEN@MITVMA.MIT.EDU (Frank Kastenholz) asks about packet drop rates for p4200s.

You did not state what software you are running. If you are running 7.4,
or if you are running 8.0 and did not change the defaults for ARP timers,
the p4200 will flush its ARP entry periodically (I think every 5 minutes),
and in the process of needing to do a new ARP a packet will get lost.
You did not say how fast you were sending packets, but 1 in 5000 sounds
about right for that scenario.

If you are running the level 8.0 software you can use the ENABLE AUTO-REFRESH
command in the ARP configuration section to make this problem disappear.

Other than this I can't think of any reason why you should lose any packets
in your simple setup.
