Specifying the Link Type to Ensure Rapid Transitions

If you connect a port to another port through a point-to-point link and the local port becomes a designated
port, the RSTP negotiates a rapid transition with the other port by using the proposal-agreement handshake
to ensure a loop-free topology.
By default, the link type is controlled from the duplex mode of the interface: a full-duplex port is considered
to have a point-to-point connection; a half-duplex port is considered to have a shared connection. If you have
a half-duplex link physically connected point-to-point to a single port on a remote switch running MSTP, you
can override the default setting of the link type and enable rapid transitions to the forwarding state.
This procedure is optional.
Before You Begin
A multiple spanning tree (MST) must be specified and enabled on the switch. For instructions, see Related
Topics.

Purpose
Enables privileged EXEC mode. Enter your password if
prompted.
Enters the global configuration mode.
Specifies the number of hops in a region before the BPDU is
discarded, and the information held for a port is aged.
For hop-count, the range is 1 to 255; the default is 20.
Returns to privileged EXEC mode.
