Spanning-tree protocols: Global configuration

Global configuration of the spanning-tree protocols RSTP, MSTP, and VSTP is supported on switches with Enhanced Layer 2 Software (ELS) configuration style. In earlier releases, the ELS software supported configuration of spanning-tree protocols on individual interfaces or on a range of interfaces. It did not support configuration of spanning-tree protocols on all interfaces or disabling spanning-tree protocols on specific interfaces. Starting with this release, CLI changes in the ELS software provide the options of configuring spanning-tree protocols on all interfaces, disabling the configuration for individual interfaces, and configuring VTSP on all VLANs or on a VLAN group.
