I think that a better way to do this is to have each switch send an SNMP trap to a network monitoring program separate from PF, which can then filter the traps and send alerts via e-mail as needed based on pre-defined rules. One possible use of this type of alert is to monitor 24/7 devices like large screen smart televisions being used for electronic signage, to send an e-mail to your campus security/police when the ethernet cable is disconnected if somebody decides that one of those TV's would be better for watching football games in their living room. Smart video projectors hanging in class/conference rooms are another theft target that could be similarly monitored for immediate security/police response... -Arthur ------------------------------------------------------------------------- Arthur Emerson III Email: [email protected] Network Administrator InterNIC: AE81 Mount Saint Mary College MaBell: (845) 561-0800 Ext. 3109 330 Powell Ave. Fax: (845) 562-6762 Newburgh, NY 12550 SneakerNet: Aquinas Hall Room 11 ------------------------------------------------------------------------------ Flow-based real-time traffic analytics software.
