Port name Port state RSTP Enter a name for the port. If multiple ports are selected, this name will be applied to all ports. Choose to enable or disable the port. Choose to enable or disable Rapid Spanning Tree Protocol (RSTP). RSTP prevents data loops by issuing frequent BPDU packets to monitor link status. STP guard LBD Note: RSTP cannot be used in conjunction with LBD. If RSTP is enabled, choose the guard type. Disabled: Do not use root guard enhancement. Root guard: Root guard enhancement allows administrators to define the position of the root bridge port in the network. Choose to enable or disable Loopback Detection (LBD). The Loopback Detection function is used to detect the loop created by a specific port while Spanning Tree Protocol (STP) is not enabled in the network, especially when the down links are hubs or unmanaged switches. The Switch will automatically shut down the port and sends a log to the administrator. Type Native VLAN Allowed VLANs 42 Note: LBD cannot be used in conjunction with RSTP. Choose the function type of the port. Trunk: Sends and receives tagged data from different VLANs. Access: Only sends and receives untagged data from the VLAN the port belongs to.
