• 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)
These additional parameters are only displayed for the CLI:
• Admin status – Shows if STA has been enabled on this interface.
