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.
