Chapter SGE2000/SGE2000P Gigabit Ethernet Switch Reference Guide 10 - Disable - Indicates that RSTP is disabled on the port. • Point-to-Point Admin Status - Indicates if a point-to-point links is established, or permits the device to establish a point-to-point link. The possible field values are: - Enable - Enables 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-topoint 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 switch port link type. It may differ from the administrative state. - Disable - Disables point-to-point link. • Point-to-Point Operational Status - Indicates the Point-to-Point operating state. • Activate Protocol Migration Test- Runs a Protocol Migration Test. The test sends Link Control Protocol (LCP) packets to test if a data link is enabled. 3. Define the relevant fields. 4. Click Apply.
