ONFIGURING THE
- 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.
