Spanning Tree Tab on SRW2048 Switches - MSTP Interface Settings

The MSTP Interface Settings screen contains parameters assigning MSTP settings to specific interfaces.
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.
MSTP. Indicates that MSTP is enabled on this interface.
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.
Backup - Provides a backup path to the designated port path toward the Spanning Tree leaves. 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.
Mode. Mode of Spanning Tree protocol.
Interface Priority (0-240,in steps of 16). Defines the interface priority for specified instance. 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.
