Configuring STP
This chapter describes how to configure the Spanning Tree Protocol (STP) on port-based VLANs on
your Cisco Systems Intelligent Gigabit Ethernet Switch Module. The switch can use either the
per-VLAN spanning-tree plus (PVST+) protocol based on the IEEE 802.1D standard and Cisco
proprietary extensions, or the rapid per-VLAN spanning-tree plus (rapid-PVST+) protocol based on the
IEEE 802.1w standard.
