Spanning Tree Design

Avaya recommends that you consider the following standard IEEE802.1D Guidelines when you design your network, no matter which Spanning Tree mode you decide to use:

• Ensure that core switches can be forced to be root bridges. For per-VLAN Spanning Tree, the function of root bridge can be shared among several core switches
• When using standard timers, ensure that the depth of the tree does not exceed 7 bridges when a default bridge timer is used
