ONFIGURING THE
• 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.
