Chapter 7 Configuring Spanning Tree Using MISTP-PVST+ or MISTP Caution If you are working from a Telnet connection to your switch, the first time you enable MISTP-PVST+ or MISTP mode, you must do so from the switch console; do not use a Telnet connection through the data port or you will lose the connection to the switch. Once you map a VLAN to a MISTP instance, you can Telnet to the switch. To change from PVST+ to MISTP-PVST+ or MISTP, perform this task in privileged mode: Task Set a spanning tree mode. Command set spantree mode {mistp | pvst+ | mistp-pvst+} This example shows how to set a switch to MISTP-PVST+ mode: Console> (enable) set spantree mode mistp-pvst+ PVST+ database cleaned up. Spantree mode set to MISTP-PVST+. Warning!! There are no VLANs mapped to any MISTP instance. Console> (enable) You can display VLAN-to-MISTP instance mapping information propagated from the root switch at runtime. This display is available only in the MISTP or MISTP-PVST+ mode. When in the PVST+ mode, use the optional keyword config, to display the list of mappings configured on the local switch. Note MAC addresses are not displayed when the keyword config is specified. To display spanning tree mapping, perform this task in privileged mode: Step 1 Step 2 Task Set spanning tree mode to MISTP. Show spanning tree mapping. Command set spantree mode mistp show spantree mapping [config] This example shows how to display the spanning tree VLAN instance mapping in MISTP mode: MISTP/MISTP-PVST+ Console> (enable) set spantree mode mistp PVST+ database cleaned up. Spantree mode set to MISTP.
