MSTP Statistics: CIST: Port Details
LABEL DESCRIPTION
Enable This field displays whether MSTP is activated on the device.
Uptime This field displays the time the port is running.
State This field displays the STP status on this port.
PortID This field displays port ID.
DsgBridgeID This is the unique identifier for the bridge in the LAN segment to which this bridge belongs
that has the lowest path cost to reach the root bridge, consisting of bridge priority plus MAC
address.
DsgPortID This is the port on the designated bridge that has the lowest path cost to reach the root
bridge, consisting of bridge priority.
ExtPortPathCost This field displays the path cost of this port to an external bridge (a bridge in a different
MST region).
ExtRootID This is the unique identifier for the external root bridge, consisting of bridge priority plus
MAC address.
ExtRootPathCost This is the path cost of the link to the root bridge.
AdminEdgePort An edge port connects to a non-STP device (such as a computer or a hub).
This field displays whether or not an administrator has set this port as an edge port.
OperEdgePort This field displays whether or not the spanning tree network has determined this port to be
an edge port.
MACOperational This field displays true when the link is up or false if the link is not up.
AdminP2PLink This field displays whether or not an administrator has set this port as a point-to-point link
to the neighbor switch.
OperP2PLink This field displays whether or not the spanning tree network has determined this port to be
a point-to-point link to the neighbor switch.
PortHelloTime This is the time interval (in seconds) at which the port transmits a configuration message.
RecvInternal This field displays whether the BPDU received was transmitted by a bridge in the same
region.
RxStpCfgBPDU This is the number of legacy STP configuration BPDUs that have been received on this port.
RxStpTcnBPDU This is the total number of legacy STP topology change notification BPDUs that have been
received on this port.
RxRstpBPDU This is the number of RSTP BPDUs that have been received on this port.
RxMstpBPDU This is the number of MSTP BPDUs that have been received on this port.
IntPortPathCost This is the path cost to the internal root bridge.
IntRootID This is the ID of the internal root bridge.
