Configuring Device Security Defining Traffic Control 4 - Classic Lock - Locks the port using the classic lock mechanism. The port is immediately locked, regardless of the number of addresses that have already been learned. - Limited Dynamic Lock - Locks the port by deleting the current dynamic MAC addresses associated with the port. The port learns up to the maximum addresses allowed on the port. Both relearning and aging MAC addresses are enabled. • Max Entries - Specifies the number of MAC addresses that can be learned on the port. The Max Entries field is enabled only if Locked is selected in the Interface Status field. In addition, the Limited Dynamic Lock mode is selected. The possible range is 1-128. The default is 1. • Action - Indicates the action to be applied to packets arriving on a locked port. The possible field values are: - Discard - Discards packets from any unlearned source. This is the default value. - Forward - Forwards packets from an unknown source without learning the MAC address. - Shutdown - Discards packets from any unlearned source and shuts down the port. The port remains shut down until reactivated, or until the device is reset. • Trap - Enables traps when a packet is received on a locked port. The possible field values are: - Enable - Enables traps. - Disable - Disables traps. • Trap Frequency (Sec) - Displays the amount of time (in seconds) between traps. The default value is 10 seconds.
