Ultimately this difference results in faster detection of failed links, and thus faster topology adjustment. By default Multiple Spanning Tree is enabled. It will tag BPDU packets to receiving devices and distinguish spanning tree instances, spanning tree regions and the VLANs associated with them. After enabling STP, configure the STP Global Settings. (shown below) Figure 4.67 - L2 Features > STP > STP Global Settings STP State: Select the Spanning Tree Protocol to be enabled or disabled. Click the Apply button to save your settings. STP Traps: STP New Root Trap: Select to enable or disable the STP new root trap option. STP Topology Change Trap: Select to enable or disable the STP topology change trap option. Click the Apply button to save your settings. STP Mode: Select the STP mode. The options to choose from are MSTP, RSTP and STP. Click the Apply button to save your settings. STP Priority: STP (0-61440): Enter the STP priority value. This value is between 0 and 61440. By default, this value is 32768. The lower the value, the higher the priority. Click the Apply button to save your settings. STP Configuration: Bridge Max Age (6-40): Enter the bridge's maximum age value here. This value must be between 6 and 40 seconds. By default, this value is 20 seconds. The maximum age value may be set to ensure that old information does not endlessly circulate through redundant paths in the network, preventing the effective propagation of the new information. Set by the Root Bridge, this value will aid in determining that the Switch has spanning tree configuration values consistent with other devices on the bridged LAN. Bridge Forward Time (4-30): Enter the bridge's forwarding time value. This value must be between 4 and 30 seconds. By default, this value is 15 seconds. Any port on the Switch spends this time in the listening state while moving from the blocking state to the forwarding state. Max Hops (1-40): Enter the maximum number of hops that are allowed. This value must be between 1 and 40 hops. By default, this value is 20 hops. This value is used to set the number of hops between devices in a spanning tree region before the BPDU (bridge protocol data unit) packet sent by the Switch will be discarded. 39
