- 206 -
This command displays the detailed settings and parameters for a specific switch port within a
particular multiple spanning tree instance. The instance <mstid> is a number that corresponds to the
desired existing multiple spanning tree instance. The <slot/port> is the desired switch port.
Syntax
show spanning-tree mst port detailed <0-4094> <slot/port>
<0-4094> - multiple spanning tree instance ID.
<slot/port> - is the desired interface number.
Default Setting
None
Command Mode
Privileged Exec
Display Message
MST Instance ID: The multiple spanning tree instance ID.
Port Identifier: The unique value to identify a port on that Bridge.
Port Priority: The priority of the port within the MST.
Port Forwarding State: Current spanning tree state of this port.
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.
