Designating the Neighbor Type

A topology could contain both prestandard and IEEE 802.1s standard compliant devices. By default, ports
can automatically detect prestandard devices, but they can still receive both standard and prestandard BPDUs.
When there is a mismatch between a device and its neighbor, only the CIST runs on the interface.
You can choose to set a port to send only prestandard BPDUs. The prestandard flag appears in all the show
commands, even if the port is in STP compatibility mode.
OL-29424-01
Purpose
Enters the global configuration mode.
Specifies an interface to configure, and enters interface
configuration mode. Valid interfaces include physical ports,
VLANs, and port-channel logical interfaces. The VLAN ID
range is 1 to 4094. The port-channel range is 1 to 48.
Specifies that the link type of a port is point-to-point.
Returns to privileged EXEC mode.
