Designated root Identifier for the bridge selected as root bridge by the Spanning Tree protocol.
VlanID Vlan ID for the bridge if PVST is used for this instance.
Root cost Cost associated to the path to the root bridge.
Root port Identifier for the port selected as root port in this bridge. When the bridge has been
selected as root bridge,
Self is displayed to indicate there is no root port.
Current maximum age Value of the Max Age parameter shown by the root bridge.
Current hello time Value of the Hello Time parameter shown by the root bridge.
Current Forward Delay Value of the Forward Delay parameter shown by the root bridge.
Port Port identifier.
Interface Interface associated to the port.
State State of the port when it comes to the Spanning Tree protocol: Discarding , if it
drops received packets, Learning , if it doesn’t process the received packets but
does use them to learn MAC addresses, Forwarding , if it processes the received
packets and Undefined , if it doesn’t do any of the previous actions.
Role Role the port plays in the Spanning Tree protocol. It can be Disabled , when the
port is disabled, Designated , for a designated port, Root , for a root port, Alternate ,
for an alternate port, Backup , for a backup port.
