• Designated Bridge — The priority and MAC address of the
device through which this port must communicate to reach the
root of the Spanning Tree.
• Designated Port — The priority and number of the port on the
designated bridging device through which this switch must
communicate with the root of the Spanning Tree.
• Oper Link Type – The operational point-to-point status of the
LAN segment attached to this interface. This parameter is
determined by manual configuration or by auto-detection, as
described for “Admin Link Type” in the STP Port/Trunk
Configuration page.
• Oper Edge Port – This parameter is initialized to the setting for
“Admin Edge Port” in the STP Port/Trunk Configuration page
(i.e., true or false), but will be set to false if a BPDU is received,
indicating that another bridge is attached to this port.
• Port Role – Roles are assigned according to whether the port
is part of the active Spanning Tree topology:
- Root: The port is connecting the bridge to the root bridge.
- Designated: The port is connecting a LAN through the bridge
to the root bridge.
- Alternate or Backup: A port that may provide connectivity
if other bridges, bridge ports, or LANs fail or are removed.
- Disabled: The role is set to disabled if a port has no role
within the Spanning Tree.
• Trunk Member — Indicates whether the port is configured as
a trunk member. (STP Port Information page only)
