Figure 7-28. MSTP Interface Settings
The MSTP Interface Settings page contains the following fields:
Instance ID — Lists the MSTP instances configured on the device. Possible field range is 1-15.
Interface — Assigns either ports or LAGs to the selected MSTP instance.
Port State— Indicates whether the port is enabled or disabled in the specific instance.
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. A Master port provides
connectivity from a MSTP region to the outlying CIST root. A Boundary port attaches MST
bridges to LAN in an outlying region. 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 root interface.
