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
