SMC Networks TigerSwitch 100 manual Configuring the Switch

CONFIGURING THE SWITCH

-Auto — The switch automatically determines if the interface is attached to a point-to-point link or to shared media.

•Admin Edge Port — You can enable this option if an interface is attached to a LAN segment that is at the end of a bridged LAN or to an end node. Since end nodes cannot cause forwarding loops, they can pass directly through to the Spanning Tree forwarding state. Specifying Edge Ports provides quicker convergence for devices such as workstations or servers, retains the current forwarding database to reduce the amount of frame flooding required to rebuild address tables during reconfiguration events, does not cause the Spanning Tree to initiate reconfiguration when the interface changes state, and also overcomes other STP-related timeout problems. However, remember that Edge Port should only be enabled for ports connected to an end-node device.

•Migration — Re-checks the appropriate BPDU format to send on the selected interface. If at any time the switch detects STP BPDUs, including Configuration or Topology Change Notification BPDUs, it will automatically set the selected interface to forced STP-compatible mode. However, you can also check this Migration check box to manually re-check the appropriate BPDU format (RSTP or STP-compatible) to send on the selected interfaces.

•Trunk – Specifies if a port is member of a trunk.
