YOU NEED TO CONFIGURE SPANNING TREE ON A CISCO SWITCH MAC
Hello Time 2 sec Max Age 20 sec Forward Delay 15 secīridge ID Priority 32781 (priority 32768 sys-id-ext 13)Īs you can see, the root bridge is a switch that has the bridge ID 80 and the SW12 interface towards the root bridge is GigabitEthernet0/2 with a cost of 4.Īlso, the interface towards SW3 (Gi0/4) is in Alternate role and Blocking state, which means that no MAC learning or flooding will happen on that interface. Let’s check the current operation of STP for VLAN 13: SW12#show spanning-tree vlan 13 Total Mac Addresses for this criterion: 2Īs you can see, the PC1 MAC address is learned from Gi0/0 (directly connected) and the PC3 MAC address is learned via SW34 over GI0/2. Let’s start with SW12 and check for VLAN 13. So without altering STP, let’s check its current status to find the root bridge and see how the MAC addresses of the hosts are learned on each switch. The type of STP used is IEEE, the Cisco implementation of 802.1D. The timers were left to default along with the default priority. If you need to quickly check the current parameters for timers and priority, you can use “show spanning-tree bridge”: SW12#show spanning-tree bridge Also, the interfaces between all three switches were configured as trunk allowing all VLANs. The VLANs and the interfaces from all switches in the respective VLANs were configured. In the above topology, everything was left at default with regards to Spanning Tree Protocol.

We will focus on configuration examples, “show” outputs and where it will be needed, plus reminders about theory will also be provided.īelow is our topology, with 2 VLANs configured and two hosts in each VLAN:

In this first article we will discuss how to check STP operation, how to influence the root bridge election and how to influence the path selection algorithm.
