Chapter SGE2000/SGE2000P Gigabit Ethernet Switch Reference Guide 10 - 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.
