An MST instance must first be created under the MST tab before an MST ID can be
selected. Once selected, all ports are shown, can be configured, and more detail can
be viewed by selecting
Edit for the desired interface.
Field
Description
Auto-calculate Port
Path Cost
Shows whether the path cost from the port to the root bridge is
automatically determined by the speed of the interface (Enabled) or
configured manually (Disabled).
Hello Timer
The amount of time the port waits between sending hello BPDUs.
Auto-calculate
External Port Path
Cost
Shows whether the path cost from the port to the CIST root is
automatically determined by the speed of the interface (Enabled) or
configured manually (Disabled).
BPDU Guard Effect
Shows the status of BPDU Guard Effect on the interface. When
enabled, BPDU Guard Effect can disable edge ports that receive
BPDU packets. This prevents a new device from entering the
existing STP topology, so devices that were originally not a part of
STP are not allowed to influence the STP topology.
Port ID
A unique value that is automatically generated based on the port
priority value and the interface index.
Port Up Time Since
Counters Last Cleared
The amount of time that the port has been up since the counters
were cleared.
Port Role
The role of the port within the CST, which is one of the following:
•
Root:
A port on the non-root bridge that has the least-cost path
to the root bridge.
•
Designated:
A port that has the least-cost path to the root bridge
on its segment.
•
Alternate:
A blocked port that has an alternate path to the root
bridge.
•
Backup:
A blocked port that has a redundant path to the same
network segment as another port on the bridge.
•
Master:
The port on a bridge within an MST instance that links the
MST instance to other STP regions.
•
Disabled:
The port is administratively disabled and is not part of
the spanning tree.
Designated Root
The bridge ID of the root bridge for the CST.
Designated Cost
The path cost offered to the LAN by the designated port.
Designated Bridge
The bridge ID of the bridge with the designated port.
Designated Port
The port ID of the designated port.
Topology Change
Acknowledge
Indicates whether the next BPDU to be transmitted for this port will
have the topology change acknowledgment flag set.
Edge Port
Indicates whether the interface is configured as an edge port
(Enabled).
Point-to-point MAC
Indicates whether the link type for the interface is a point-to-point
link.
CST Regional Root
The bridge ID of the bridge that has been elected as the root bridge
of the CST region.
CST Path Cost
The path cost from the interface to the CST regional root.
