PVST+ and Rapid PVST+Configuration on Packet Tracer
PVST+ Configuration on Packet Tracer
In this Spanning Tree Configuration Example, we will configure STP with STP Mode PVST+. As you know, PVST+ is the STP Mode that uses one STP instances per VLAN.
For this PVST+ Example, we will use the below switch topology.
We will do the below configuration steps for our PVST+ Configuration on Cisco Packet Tracer.
1. Defining VLANs on the swithes (VLAN 1,2,3,4)
2. Setting all switch interfaces as Trunk and se tthe allowed VLANs
3. Setting STP Mode as PVST+
4. Setting VLANs in STP Topology (VLAN 1,2,3,4)
5. Verification of PVST+ Configuration
6. PVST+ Manuplation Commands
Defining VLANs on the swithes
We will define VLAN 1,2,3 and for on each switch. VLAN 1 is also defined by default. SO it is not necessary to create it. The below configuration will be done on each switch.
Setting all switch interfaces as Trunk
We will configure allt he interfaces between the switches as Trunk interfaces and we will set the allowed VLANs on these interfaces. Allowed VLANs are our VLANs that we have created before. We will do the same configuration on each switch.
Setting STP Mode as PVST+
We will set the stp mode as PVST on each switch.
Setting VLANs in STP Topology
After setting the STP Mode, the VLANs in the PVST Domain will be defined on each switch like below.
After the configuration, we will save the configuration on each switch.
Verification of PVST+ Configuration
To verify our PVST+ configuration, we will use the below commands. You can find the outpıuts of some of them to learn PVST+ better.
