Role
The "Role" column specifies which role the port adopts:
– Root
The port has the lowest path costs from the device itself to the CIST regional root
bridge.
– Designated
Via this port, a connected network segment reaches the CIST regional root bridge with
minimum path costs.
– Alternate
The port is blocked and provides an alternative path to the CIST regional root bridge.
– Backup
The port is blocked and provides an alternative path to a collision domain that is
already connected via a different port.
●
FWD Transitions
The "FWD Transitions" column shows the number of changes from the listening status to
the forwarding status.
●
Edge
The "Edge" column shows whether or not an end device is connected to the port.
With an end device, an IE switch can switch over the port faster without taking into
account spanning tree frames. If a spanning tree frame is received despite this setting,
the port automatically changes to the no status.
– yes
An edge port is connected to this port.
– no
There is a Spanning Tree or Rapid Spanning Tree device at this port.
●
P.t.P.
There is a point-to-point link when two RSTP-compliant network components are
connected together over this port.
The following statuses are possible:
– Yes
There is a point-to-point link.
– No
There is no a point-to-point link.
