Mode—Indicates the current Spanning Tree mode. The Spanning Tree mode is selected in the
Spanning Tree Global Settings page. The possible field values are:
Classic STP—Indicates that Classic STP is enabled on the device.
Rapid STP—Indicates that Rapid STP is enabled on the device.
Multiple STP—Indicates that Multiple STP is enabled 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 an interface, the interface 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 switch
port link type. It may differ from the administrative state.
Point-to-Point Operational Status — The Point-to-Point operating state.
Activate Protocol Migrational — When checked, enables PPP sending Link Control Protocol
(LCP) packets to configure and test the data link.
