Status
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
Notice
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.
4.9.5 MSTP Properties
MSTP provides differing load balancing scenarios. For example, while port A is blocked in one STP instance, the same port is
placed in the Forwarding State in another STP instance. The MSTP Properties screen (see figure 4-52) contains information for
defining global MSTP settings, region names, MSTP revisions, and maximum hops.
• Rapid STP, which indicates that Rapid STP is enabled on the device.
• Multiple STP, which indicates that Multiple STP is enabled on the device.
This 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.
Indicates if RSTP is enabled on the interface.
Indicates if a point-to-point links are established, or permits the device to establish a
point-to-point link. The possible field values are:
• Auto. Point-to-point links are automatically established by the device.
• Enabled, enables the device to establish a point-to-point link.
• Disabled, where disables point-to-point link.
Indicates the Point-to-Point operating state. To run a migration test, press Activate
next to the Activate Protocol Migration Test field. The test sends Link Control
Protocol (LCP) packets to test if a data link is enabled.
