Type — Indicates whether MSTP treats the port as a point-to-point port or a port connected to a
hub and whether the port is internal to the MST region or a boundary port. If the port is a
boundary port, it also indicates whether the device on the other side of the link is working in RSTP
or STP mode
Role — Indicates the port role assigned by the STP algorithm in order to provide to STP paths.
The possible field values are:
Root — Provides the lowest cost path to forward packets to root device.
Designated — Indicates the port or LAG via which the designated device is attached to the
LAN.
Alternate — Provides an alternate path to the root device from the interface.
Backup — Provides a backup path to the designated LAN. Backup ports occur only when two
ports are connected in a loop by a point-to-point link. Backup ports also occur when a LAN
has two or more connections connected to a shared segment.
Disabled — Indicates the port is not participating in the Spanning Tree.
Interface Priority — Defines the interface priority for the specified instance. The priority range is
0-240 in steps of 16. The default value is 128.
Path Cost — Indicates the port contribution to the Spanning Tree instance. The range should
always be 1-200,000,000.
Default Path Cost — Indicates that the default path cost is assigned according to the method
selected on the Spanning Tree Global Settings page.
Designated Bridge ID — The bridge ID number that connects the link or shared LAN to the root.
Designated Port ID — The port ID number on the designated bridge that connects the link or the
shared LAN to the root.
Designated Cost — Cost of the path from the link or the shared LAN to the root.
Forward Transitions — Number of times the port changed to the forwarding state.
Remain Hops — Indicates the number of hops remaining to the next destination.
