Configurable Data
Port Priority
- The priority for a particular port within the CST. The port priority is set in multiples of
16. For example, if you attempt to set the priority to any value between 0 and 15, it will be set to 0. If
you attempt to set any value between 16 and (2*16-1) it will be set to 16 and so on.
Port Path Cost
- Set the Path Cost to a new value for the specified port in the common and internal
spanning tree. It takes a value in the range of 1 to 200000000.
External Port Path Cost
- Set the External Path Cost to a new value for the specified port in the
spanning tree. It takes a value in the range of 1 to 200000000.
Non-Configurable Data
Auto-calculate Port Path Cost
- Displays whether the path cost is automatically calculated
(Enabled) or not (Disabled). Path cost will be calculated based on the link speed of the port if the
configured value for Port Path Cost is zero.
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.
BPDU Guard Effect
– Displays whether BPDU Guard Effect is enabled or disabled.
Port ID
- The port identifier for the specified port within the CST. It is made up from the port priority
and the interface number of the port.
Port Up Time Since Counters Last Cleared
- Time since the counters were last cleared, displayed
in Days, Hours, Minutes, and Seconds.
Port Forwarding State
- The Forwarding State of this port.
Port Role
- Each MST Bridge Port that is enabled is assigned a Port Role for each spanning tree.
The port role will be one of the following values: Root Port, Designated Port, Alternate Port, Backup
Port, Master Port, or Disabled Port.
Designated Root
- Root Bridge for the CST. It is made up using the bridge priority and the base
MAC address of the bridge.
Designated Cost
- Path Cost offered to the LAN by the Designated Port.
Designated Bridge
- Bridge Identifier of the bridge with the Designated Port. It is made up using the
bridge priority and the base MAC address of the bridge.
Designated Port
- Port Identifier on the Designated Bridge that offers the lowest cost to the LAN. It
is made up from the port priority and the interface number of the port.
Topology Change Acknowledge
- Identifies whether the next BPDU to be transmitted for this port
would have the topology change acknowledgement flag set. It is either "True" or "False".
Edge port
- indicates whether the port is enabled as an edge port. It takes the value "Enabled" or
"Disabled".
Point-to-point MAC
- Derived value of the point-to-point status.
CST Regional Root
- Bridge Identifier of the CST Regional Root. It is made up using the bridge
priority and the base MAC address of the bridge.
CST Path Cost
- Path Cost to the CST Regional Root.
Loop Inconsistent State
- This parameter identifies whether the port is in loop inconsistent state.
Transitions Into Loop Inconsistent State
- The number of times this interface has transitioned into
loop inconsistent state.
Transitions Out Of Loop Inconsistent State
- The number of times this interface has transitioned
out of loop inconsistent state.
