‧ Extension – Multiple Spanning Tree Protocol (MSTP) : Defines an extension to RSTP to further develop the
usefulness of virtual LANs (VLANs). This "Per-VLAN" Multiple Spanning Tree Protocol configures a separate Spanning
Tree for each VLAN group and blocks all but one of the possible alternate paths within each Spanning Tree.
The STP System Configuration screen in Figure 4-7-4 appears.

Object Description

Protocol Version The STP protocol version setting. Valid values are:

STP (IEEE 802.1D Spanning Tree Protocol)

RSTP (IEEE 802.2w Rapid Spanning Tree Protocol)

MSTP (IEEE 802.1s Multiple Spanning Tree Protocol)
 Bridge Priority Controls the bridge priority. Lower numeric values have better priority. The bridge
priority plus the MSTI instance number, concatenated with the 6-byte MAC
address of the switch forms a Bridge Identifier.
For MSTP operation, this is the priority of the CIST. Otherwise, this is the priority
of the STP/RSTP bridge.

Forward Delay The delay used by STP Bridges to transition Root and Designated Ports to
