–
Rapid STP
— Indicates that Rapid STP is enabled on the device.
–
Multiple STP
— Indicates that Multiple STP is enabled on the device.
•
Type
— Indicates if the port is a point-to-point port, or a port connected to a hub. The possible field
values are:
–
Boundary Port
— Indicates the port is a boundary port. 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
–
Master Port
— Indicates the port is a master port. A Master port provides connectivity from
a MSTP region to the outlying CIST root.
–
Internal
— Indicates the port is an internal port.
•
Port Priority
— 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.
•
Port State
— Indicates whether the port is enabled for the specific instance. The possible field values
are:
–
Enable
— Enables the port for the specific instance.
–
Disable
— Disables the port for the specific instance.
–
Forwarding
— Enables forwarding all multicast packets on a port.
•
Designated Cost
— Indicates that the default path cost is assigned according to the method selected
on the Spanning Tree Global Settings page.
•
Designated Bridge ID
— Indicates that the bridge ID number that connects the link or shared LAN
to the root.
•
Designated Port ID
— Indicates that the Port ID number on the designated bridge that connects the
link or the shared LAN to the root.
•
Remaining Hops
— Indicates the hops remaining to the next destination.
–
Static
— Attaches the port to the Multicast group as static member in the Static Row. The
port/LAG has joined the Multicast group statically in the Current Row.
–
Forbidden
— Forbidden ports are not included the Multicast group, even if IGMP snooping
designated the port to join a Multicast group.
–
Non
— The port is not part of a Multicast group.
