Configuring and Monitoring Port SecurityReading Intrusion Alerts and Resetting Alert FlagsThe log shows the most recent intrusion at the top of the listing. You cannotdelete Intrusion Log entries (unless you reset the switch to its factory-defaultconfiguration). Instead, if the log is filled when the switch detects a newintrusion, the oldest entry is dropped off the listing and the newest entryappears at the top of the listing.Keeping the Intrusion Log Current by Resetting AlertFlagsWhen a violation occurs on a port, an alert flag is set for that port and theviolation is entered in the Intrusion Log. The switch can detect and handlesubsequent intrusions on that port, but will not log another intrusion on theport until you reset the alert flag for either all ports or for the individual port.N o t e o n On a given port, if the intrusion action is to send an SNMP trap and then disableS e n d - D i s a b l e the port (send-disable), and an intruder is detected on the port, then the switchO p e r a t i o n sends an SNMP trap, sets the port’s alert flag, and disables the port. If you re-enable the port without resetting the port’s alert flag, then the port operatesas follows:■ The port comes up and will block traffic from unauthorized devices itdetects.■ If the port detects another intruder, it will send another SNMP trap, butwill not become disabled again unless you first reset the port’s intrusionflag.This operation enables the port to continue passing traffic for authorizeddevices while you take the time to locate and eliminate the intruder. Other-wise, the presence of an intruder could cause the switch to repeatedly disablethe port.9-31
