- Native VLAN ID(1-4094) - Enter the VLAN ID used for untagged traffic to trunk ports, or check None. The remaining fields on this page are display-only, and describe the port configuration of the profile. The following fields are described: Port Security fields: - Mode - Learning mode. The possible options are: • 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 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 - Displays the maximum number of MAC addresses that can be learned on the port. - Action on Violation - Action to be applied to packets arriving on a locked port. The possible options are: • Discard - Discard the packets from any unlearned source. • Forward - Forward the packets from an unknown source, without learning the MAC address. • Shutdown - Discard the packet from any unlearned source, and shut down the port. Ports remain shutdown until they are reactivated, or the device is reset. Spanning Tree fields: - Point-to-Point Admin Status - Displays whether a point-to-point links is established. The possible options are: • Enable - Enables the device to establish a point-to-point link, or specifies for the device to automatically establish a point-to-point link. To establish communications over a point-to-point link, the originating PPP first sends Link Control Protocol (LCP) packets to configure and test the data link. After a link is established and optional facilities are negotiated as needed by the LCP, the originating PPP sends Network Control Protocols (NCP) packets to select and configure one or more network layer protocols.
