دوتا تعریف بود برای spanning-tree link-type
Link Type
Rapid connectivity is established only on point-to-point links. You must configure ports explicitly to a host or switch. However, cabling in most networks meets this requirement, and you can avoid explicit configuration by treating all full-duplex links as point-to-point links by entering the
spanning-tree linktype command
spanning-tree link-type
Use the
spanning-tree link-type interface configuration command to override the default link-type setting, which is determined by the duplex mode of the interface, and to enable rapid spanning-tree transitions to the forwarding state. Use the
no form of this command to return to the default setting.
spanning-tree link-type {
point-to-point |
shared}
no
spanning-tree link-type
Syntax Description
point-to-point
Specify that the link type of an interface is point-to-point.
shared
Specify that the link type of an interface is shared.
Defaults
The switch derives the link type of an interface from the duplex mode. A full-duplex interface is considered a point-to-point link, and a half-duplex interface is considered a shared link.

12.1(19)EA1
This command was introduced.
Usage Guidelines
You can override the default setting of the link type by using the
spanning-tree link-type command. For example, a half-duplex link can be physically connected point-to-point to a single interface on a remote switch running the Multiple Spanning Tree Protocol (MSTP) or the rapid per-VLAN spanning-tree plus (rapid-PVST+) protocol and be enabled for rapid transitions.
Examples
This example shows how to specify the link type as shared (regardless of the duplex setting) and to prevent rapid transitions to the forwarding state:
Switch(config-if)# spanning-tree link-type shared
