Warning when using VLANs

•Time between transmitted Conﬁguration BPDUs

•Time the switch spends in the Listening and Learning states

It is important to be aware of problems that may arise when using Spanning Tree and VLANs. The Spanning Tree can use alternative paths (such as different ports) to get messages to their destination.

Why change these from their defaults?

The diagram above, shows two switches. On the left, we see the two switches connected and the ports are grouped in two VLANs: A and B. On the right, we have enabled STP; STP blocks the path between X and Z (to avoid looping) and, therefore, destroys the VLAN setup (because VLAN B needs these ports to receive messages).

The switch is delivered with Spanning Tree default values set to those recommended by the IEEE 802.1d standard. These values are conser- vative worst-case estimates for LANs consisting of a large number of switches. Therefore, changing these default values may improve the performance of your network.
