Chapter 5 Spanning Tree Spanning Tree Protocol (STP) provides tree topography for any arrangement of bridges. STP also provides one path between end stations on a network, eliminating loops. Loops occur when alternate routes exist between hosts. Loops in an extended network can cause bridges to forward traffic indefinitely, resulting in increased traffic and reducing network efficiency. Configuration Using the Web-based Utility Root Forward delay (sec) The device forward delay time.

Appendix A About Gigabit Ethernet and Fiber Optic Cabling Appendix A: About Gigabit Ethernet and Fiber Optic Cabling Gigabit Ethernet Gigabit Ethernet runs at speeds of 1Gbps (Gigabit per second), ten times faster than 100Mbps Fast Ethernet, but it still integrates seamlessly with 100Mbps Fast Ethernet hardware. Users can connect Gigabit Ethernet hardware with either fiber optic cabling or copper Category 5e cabling, with fiber optics more suited for network backbones.
Appendix B Appendix B: About Switch Stacking A switch may operate in one of two modes: Stack or Standalone. You can select either mode during software boot or using the web-based utility’s Setup > Summary screen, with the new mode taking effect after the unit is reset. The factory default is Stack mode. Standalone Mode A switch operating in Standalone mode runs as an independent, single unit. All ports of a standalone switch operate as normal Ethernet links.
Appendix B the Console port, Telnet or Web-based Utility) and reset the units to make this assignment permanent. The unit that is assigned number 1 will act as the Master; this is indicated by the Stack Master LED on its front panel being lit amber. The unit that is assigned number 2 will act as the Backup Master. Stack Resiliency A stack’s topology may be either Ring or Chain.
Appendix B Stack Units Startup Process Whenever a unit in stack mode is initialized (powered up or rebooted) it goes through the same exact process, consisting of the following three steps: 1. Master Discovery/Election. 2. Unit ID allocation by the Master (including duplicate Unit ID conflict resolution) 3. Unit/port configuration by the Master About Switch Stacking ID was originally assigned automatically or manually. (Such units are called Master-enabled units).
Appendix B • If both duplicate units are in auto (self ordering) mode, then the unit ID will be decided by the Mac address. The unit with the lower Mac will keep its unit ID. The other will be reassigned a new unit ID. • If one of the duplicates is in auto (self ordering) mode and the other unit is in manual mode then the manual mode unit will keep its ID and the other will be reassigned a new unit ID. • If both duplicate units are in manual mode then both of them will be shut down.
Appendix B • If the incoming unit did not have an assigned Unit ID (that is, it was in factory default mode), it will be assigned the lowest available Unit ID by the Master. It is strongly recommended that automatic assigned unit ID mode be used since it provides better resiliency to the stack.
Appendix B • If the incoming unit already has an assigned Unit ID, and that Unit ID is unused in the current stack, the incoming unit will keep its assigned Unit ID and the Master will apply to it any configuration relevant to that Unit ID.
Appendix B before the split. Since the Backup Master was not acting as a master prior to the split, it will initiate a topology database and port-learning process. Traffic might be halted for a short period of time until synchronization (unit and port configuration) is completed. New units learned by the Backup Master will notify the system administrator (using SYSLOG messages and SNMP traps). d.
Appendix B It should be emphasized that when two stacks are combined, all of the configuration information for one of the stacks will be lost. Only the surviving master (after the discovery/election process completes) will maintain its configuration information. The best practice to combine two stacks is to reset the switches in one stack to the factory defaults and then add the switches as described in the “Adding Units to a Running Stack” subsection of section “Normal (SelfOrdering) Stack).
