hello time
Specifies the amount of time between the transmission of configura-
tion BPDUs.
Root max age
Specifies the maximum age of Spanning Tree Protocol information
learned from the network on any port before it is discarded.
Root priority
This object specifies the priority of the bridge that is currently selected
as root-bridge for the network.
Root port
Specifies the port number of the port which offers the lowest cost path
from this bridge to the root bridge.
SAP Identifier
The ID of the access port where this SAP is defined.
BPDU encap
Specifies the type of encapsulation used on BPDUs sent out and
received on this SAP.
Port Number
Specifies the value of the port number field which is contained in the
least significant 12 bits of the 16-bit port ID associated with this SAP.
Priority
Specifies the value of the port priority field which is contained in the
most significant 4 bits of the 16-bit port ID associated with this SAP.
Cost
Specifies the contribution of this port to the path cost of paths towards
the spanning tree root which include this port.
Designated Port
Specifies the port identifier of the port on the designated bridge for this
port's segment.
Designated Bridge
