Configuring Interface Settings for STA
– 305 –
Admin Link Type – The link type attached to this interface.
Point-to-Point – A connection to exactly one other bridge.
Shared – A connection to two or more bridges.
Auto – The switch automatically determines if the interface is
attached to a point-to-point link or to shared media. (This is the
default setting.)
Root Guard – STA allows a bridge with a lower bridge identifier (or
same identifier and lower MAC address) to take over as the root bridge
at any time. Root Guard can be used to ensure that the root bridge is
not formed at a suboptimal location. Root Guard should be enabled on
any designated port connected to low-speed bridges which could
potentially overload a slower link by taking over as the root port and
forming a new spanning tree topology. It could also be used to form a
border around part of the network where the root bridge is allowed.
(Default: Disabled)
Migration – 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 use the Protocol Migration button to
manually re-check the appropriate BPDU format (RSTP or STP-
compatible) to send on the selected interfaces. (Default: Disabled)
