>Description:
I have updated FreeBSD 4.2-R -> 4.6-S and 4.3-R -> 4.6-S (20020712) via NFS on two
servers with four ethernet adaptors (4 fxp on one and 2fxp+ed+rl on other). And appear
the problem with overfull traffic on third and fourth adaptors at a promiscuous mode
(by tcpdump, arpwatch).For example:
/kernel: fxp0: promiscuous mode disabled
>netstat -I fxp0 -w 1
input (fxp0) output
packets errs bytes packets errs bytes colls

98 0 69212 99 0 24627 0
.......

The avarege is same.No problem.
But on fxp2 and fxp3 I can see overfull traffic - maybe whole traffic on ethernet.
For example:
/kernel: fxp1: promiscuous mode disabled
>netstat -I fxp3 -w 1
input (fxp3) output
packets errs bytes packets errs bytes colls
0 0 72 0 0 232 0
1 0 60 1 0 50 0
1 0 318 1 0 508 0
4 0 240 4 0 200 0
5 0 60 5 0 50 0
/kernel: fxp0: promiscuous mode enabled
>netstat -I fxp3 -w 1
input (fxp3) output
packets errs bytes packets errs bytes colls
224 0 66748 0 0 0 0
226 0 37238 0 0 0 0

At promiscuous mode the traffic biggest.
The same on second router on rl0 and ed0 (3rd and 4th adaptors).
Whats the problem ???
Sorry for my english.
