- Disable—The port is not considered point-to-point for RSTP purposes,
which means that STP works on it at regular speed, as opposed to rapid
speed.
- Auto—Automatically determines switch status by using RSTP BPDUs.
• Point-to-Point Operational Status—Displays the Point-to-Point operating
status if the Point-to-Point Administrative Status is set to Auto.
• Role—Displays the role of the port that has been assigned by STP to
provide STP paths. The possible roles are:
- Root—Lowest cost path to forward packets to the Root Bridge.
- Designated—The interface through which the bridge is connected to the
LAN, that provides the lowest cost path from the LAN to the Root Bridge.
- Alternate—Provides an alternate path to the Root Bridge from the root
interface.
- Backup—Provides a backup path to the designated port path toward the
Spanning Tree leaves. Backup ports occur 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—The port is not participating in Spanning Tree.
• Mode—Displays the current Spanning Tree mode: Classic STP or RSTP.
• Fast Link Operational Status—Displays whether the Fast Link (Edge Port)
is enabled, disabled, or automatic for the interface. The values are:
- Enabled—Fast Link is enabled.
- Disabled—Fast Link is disabled.
- Auto—Fast Link mode is enabled a few seconds after the interface
becomes active.
• Port Status—Displays the RSTP status on the specific port.
- Disabled—STP is currently disabled on the port.
- Blocking—The port is currently blocked, and it cannot forward traffic or
learn MAC addresses.
- Listening—The port is in Listening mode. The port cannot forward traffic,
and cannot learn MAC addresses.
