Re: Network analysis software

Keep in mind that under default conditions, you won't see a lot with any
analyzis tool that uses packet sniffing (like ethereal), since you are
on a switched LAN; i.e. only broadcast traffic and traffic destined for
MAC addresses connected to that specific port are seen on a port.

But the Bay switches might have a facility like a Switch Port Analyzer
(don't know; never used Bay), which in effect redirects the traffic from
a specific port to an analyzer port, where you can then connect a
sniffer and listen to traffic on your selected, analyzed port.

If you just want traffic stats per port, a tool like MRTG (Andreas sent
you the link) is able to graph SNMP variables, under condition that your
Bay switch supports SNMP and makes those varaibles available.
