Definition
Indicates whether auto calculation for port path cost is enabled or not (disabled).
The configured path cost for the specified interface.
Indicates whether auto calculation for external port path cost is enabled.
The cost to get to the root bridge of the CIST across the boundary of the region. This means that if the
port is a boundary port for an MSTP region, then the external path cost is used.
Identifier of the designated root for this port within the CST.
The root path cost to the LAN by the port.
The bridge containing the designated port.
Port on the Designated Bridge that offers the lowest cost to the LAN.
Value of flag in next Configuration Bridge Protocol Data Unit (BPDU) transmission indicating if a
topology change is in progress for this port.
The hello time in use for this port.
The configured value indicating if this port is an edge port.
The derived value of the edge port status. True if operating as an edge port; false otherwise.
Derived value indicating if this port is part of a point to point link.
The regional root identifier in use for this port.
The internal root path cost to the LAN by the designated external port.
