• Mode - Displays the STP mode by which STP is enabled on the device. The possible field values are: - Classic STP - Enables Classic STP on the device. This is the default value. - Rapid STP - Enables Rapid STP on the device. • Multiple STP - Enables Multiple STP on the device. • Fast Link Operational Status - Indicates if Fast Link is enabled or disabled for the port or LAG. If Fast Link is enabled for a port, the port is automatically placed in the forwarding state. • Point-to-Point Admin Status - Enables or disables the device to establish a point-to-point link, or specifies for the device to automatically establish a point-to-point link. To establish communications over a point-to-point link, the originating PPP first sends Link Control Protocol (LCP) packets to configure and test the data link. After a link is established and optional facilities are negotiated as needed by the LCP, the originating PPP sends Network Control Protocols (NCP) packets to select and configure one or more network layer protocols. When each of the chosen network layer protocols has been configured, packets from each network layer protocol can be sent over the link. The link remains configured for communications until explicit LCP or NCP packets close the link, or until some external event occurs. This is the actual device port link type. It may differ from the administrative state. • Point-to-Point Operational Status - The Point-to-Point operating state. • Activate Protocol Migrational Test - When selected, enables PPP sending Link Control Protocol (LCP) packets to configure and test the data link. Enabling RSTP 1 Open the Rapid Spanning Tree (RSTP) page. 2 Define the Point-to-Point Admin, Point-to-Point Oper, and the Activate Protocol Migration fields. 3 Click Apply Changes. Rapid STP is enabled, and the device is updated. 316 Configuring Device Information
