Description

When you explicitly configure STP, a switch uses the IEEE 802.1D 2004 specification, force version 0. This configuration runs a version of RSTP that is compatible with the classic, basic STP (defined in the IEEE 802.1D 1998 specification).

The remaining statements are explained separately. See CLI Explorer.

Note:

Although the edge configuration statement appears in the CLI on the switch, this statement has no effect on the switch operation if you configure it.

Default

STP is disabled; by default, RSTP is enabled on all Ethernet switching ports.

Required Privilege Level

routing—To view this statement in the configuration.routing-control—To add this statement to the configuration.

Release Information

Statement introduced in Junos OS Release 9.0.
