vlan-group

Syntax

Hierarchy Level

Description

Configure VSTP for a VLAN group.

Best Practice:

Configure RSTP when you configure VSTP. RSTP overhead is minimal and this configuration ensures that a spanning-tree protocol is running on all VLANs on your switch, even when your switch is supporting more than the maximum number of allowed VSTP VLANs.

Note:

Ensure that the interface is a member of all VLANs before you add the interface to the VSTP configuration. If the interface is not a member of all VLANs, this VSTP configuration will fail when you try to commit it.

The remaining statements are explained separately. See CLI Explorer.
