Release Information

Statement introduced in JUNOS Release 9.0 for EX-series switches.

Description

When you explicitly configure STP, the EX-series switches use 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.

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.
