Gustavo, you can use the syslog feature on the Cisco switch to determine
this.  Cat5K/6K/4K switches have the ability to do syslog logging using
the commands:

set logging level all 5 default
set logging server <ip address of FreeBSD machine>
set logging server facility LOCAL7

Then, on your FreeBSD box, add a line to /etc/syslog.conf:

local7.info		/var/log/cisco.log

Then,

touch /var/log/syslog.log

If you have a 2900xl/3500xl switch, then you need to use Cisco IOS
commands for syslog:

# config t
# logging trap informational
# logging <ip address of FreeBSD machine>
# logging facility local7

The other option is to install /usr/ports/net/ucd-snmp, and setup the trap
receiver to listen for SNMP traps.  To configure these on a Catalyst
running switch code:

set snmp community read-only <community string>
set snmp community read-write <community string>
set snmp trap enable 
set snmp trap <ip address of FreeBSD box>

On an IOS switch:

# config t
# snmp-server community <comm string> RO
# snmp-server community <comm string> RW
# snmp-server enable traps snmp
# snmp-server host <ip address of FreeBSD box>

Then, scan your log files for link down traps or LINK syslog messages.
