Did you mean the statistics on switch ?
Yes
Output queue 0/40, 0 drops; input queue 0/75, 0 drops
5 minute input rate 6031000 bits/sec, 877 packets/sec
5 minute output rate 3104000 bits/sec, 1160 packets/sec
1631516276 packets input, 4237296754 bytes
Received 161839 broadcasts, 212836721 runts, 0 giants, 0 throttles
212836725 input errors, 0 CRC, 4 frame, 0 overrun, 84223 ignored
0 watchdog, 0 multicast
0 input packets with dribble condition detected
194910163 packets output, 3947790078 bytes, 0 underruns
0 output errors, 0 collisions, 0 interface resets
0 babbles, 0 late collision, 0 deferred
0 lost carrier, 0 no carrier
0 output buffer failures, 0 output buffers swapped out
No, it doesn't affect the switch statistic because bug is in
receive part of FreeBSD driver - it doesn't affect packets sent out to switch.
It doesnt seem to affect performance. When I did some benchmarks way back
with netperf, the difference in vlan performance vs native fxp performance
was barely significant.
