spanning-tree
link-type [auto | point-to-point | shared]
Use the
spanning-tree link-type
command to configure the spanning tree protocol link type for each
interface. Use the
no
version of the command to return to the default setting.
Syntax Description
auto
Link type is determined by the port’s duplex settings.
point-to-point
Link type is manually set to point-to-point, regardless of duplex settings.
shared
Link type is manually set to shared, regardless of duplex settings.
Default Values
By default, the interface is set to auto.
Functional Notes
This command overrides the default link type setting determined by the duplex of the individual port. By
default, a port configured for half-duplex is set to
shared
link type, and a port configured for full-duplex is
set to
point-to-point
link type. Setting the link type manually overrides the default and forces the port to
use the specified link type. Use the
link-type auto
command to restore the convention of determining link
type based on duplex settings.
Usage Examples
The following example forces the link type to
point-to-point
, even if the port is configured to be
half-duplex:
ProCurve(config)#
interface eth 0/1
ProCurve(config-eth 0/1)#
spanning-tree link-type point-to-point
Technology Review
Rapid transitions are possible in RSTP (rapid spanning-tree protocol) by taking advantage of point-to-point
links (a port is connected to exactly one other bridge) and edge-port connections (a port is not connected
to any additional bridges). Setting the link-type to
auto
allows the spanning-tree to automatically configure
the link type based on the duplex of the link. Setting the link type to
point-to-point
allows a half-duplex
link to act as if it were a point-to-point link.
