Port Role:
Indicate the port role is root or designate.
Auto-calculate Port Path Cost:
Indicate the port auto-calculate port path cost.
Port Path Cost:
Configured value of the Internal Port Path Cost parameter.
Designated Root:
The Identifier of the designated root for this port.
Designated
Port Cost:
Path Cost offered to the LAN by the Designated Port.
Designated
Bridge:
Bridge Identifier of the bridge with the Designated Port.
Designated Port Identifier:
Port on the Designated Bridge that offers the lowest cost to the LAN.
If 0 (defined as the default CIST ID) is passed as the <0-4094>, then this command displays the
settings and parameters for a specific switch port within the common and internal spanning tree. The
<slot/port> is the desired switch port. In this case, the following are displayed.
Port Identifier:
The port identifier for this port within the CST.
Port Priority:
The priority of the port within the CST.
Port Forwarding State:
The forwarding state of the port within the CST.
Port Role:
The role of the specified interface within the CST.
Auto-calculate Port Path Cost:
Indicate the port auto-calculate port path cost
Port Path Cost:
The configured path cost for the specified interface.
Auto-calculate External Port Path Cost
- Displays whether the external path cost is automatically
calculated (Enabled) or not (Disabled). External Path cost will be calculated based on the link speed
of the port if the configured value for External Port Path Cost is zero.
External Port Path Cost
- The External Path Cost of the specified port in the spanning tree.
Designated Root:
Identifier of the designated root for this port within the CST.
Designated Port Cost:
Path Cost offered to the LAN by the Designated Port.
Designated Bridge:
The bridge containing the designated port.
Designated Port Identifier:
Port on the Designated Bridge that offers the lowest cost to the LAN.
Topology Change Acknowledgement:
Value of flag in next Configuration Bridge Protocol Data
Unit (BPDU) transmission indicating if a topology change is in progress for this port.
Hello Time:
The hello time in use for this port.
Edge Port:
The configured value indicating if this port is an edge port.
Edge Port Status:
The derived value of the edge port status. True if operating as an edge port; false
otherwise.
Point To Point MAC Status:
Derived value indicating if this port is part of a point to point link.
CST Regional Root:
The regional root identifier in use for this port.
CST Port Cost:
The configured path cost for this port.
Transitions Into Loop Inconsistent State
: The count number of transitions into loop inconsistent
state.
Transitions Out Of Loop Inconsistent State
: The count number of transitions out of loop
inconsistent state.
