Modular L3 Ethernet Switch User's Guide ◊ False - Indicates that each port of a device is in STP mode, whether or not a VLAN was defined. Figure 6- 71. Spanning Tree Parameters window Bridge Setup Parameter tab The Bridge Setup Parameter tab displays the following fields: ♦ Bridge Priority - Identifies the bridge priority and is part of the bridge identifier. The bridge identifier is 8 octets long, and the two most significant octets indicate the bridge priority. The bridge with the lowest value is the root. ♦ Bridge Max Age (Seconds) - Indicates the amount of time a bridge waits before implementing a topological change. The possible values are 6-40 seconds. The default is 20 seconds. This parameter is configured on all the bridges participating in the STP, but only the one belonging to the elected Root Bridge is used. It is strongly recommended to use: Max age ≥ Hello time x 2 + 1.0s. ♦ Bridge Hello Time (Seconds) - Indicates the amount of time a root bridge waits between configuration messages. The possible values are 1-10 seconds. The default is 2 seconds. Lengthening the Bridge Hello Time lowers the overhead time of the Spanning Tree Protocol (STP). ♦ Bridge Forwarding Delay (Seconds) - Indicates the amount of time a bridge remains in a listening and learning state before forwarding packets. The possible values are 4-30 seconds. Bridge Forward Delay is also used when a topology change is detected. Bridge Forward Delay ensures that Bridges use a consistent value for the Forward Delay Timer when changing the Port State to forwarding. The default is 15 seconds. 106
