Unit Numbering within the Stack 61■ When a port is operating in stack mode it will no longer beconfigurable in the normal way, that is, you cannot control portfeatures such as auto-negotiation, VLANs, static addresses, STP,Aggregated Links, Resilient Links, and so on. However, it is possible tospecify the stack VLAN.Figure 20 Stack example (using 4 units)Unit Numberingwithin the StackWhen a stack is created using the Switch 4500 the unit numbering canbe determined in two ways.■ You can manually assign unit IDs 1 to 8 to specific units using thechange[self-unit, unit-id] to [1-8,auto-numbering] command from the System View. If youmanually assign unit IDs to a Switch via the change command the IDswill be retained after a power cycle.If you add a unit to a stack that has previously been manuallyconfigured with a unit ID and this conflicts with an ID already withinthe stack, then the Switch with the lowest MAC address assumes theID in question and the other unit will automatically renumber.3Com recommends that you manually assign the unit IDs within the stackif you wish to have predictability of knowing which units have which IDsat all times.■ Stack topology is ‘discovered’ and the units auto-number their IDs.Adding and removing units from the stack does not cause anyrenumbering to occur and the stack will continue to work normally.3CR17561-91 SuperStack 3 Switch 4500 26-Port1000BASE-X10/100BASE-TX 10/100/1000BASE-TSpeed: (100Base-TX) Green = 100Mbps Yellow = 10Mbps (1000Base-X) Green = 1000Mbps Yellow = 10/100Mbps Duplex: Green = Full Duplex, Yellow = Half Duplex2625 25 263CR17561-91 SuperStack 3 Switch 4500 26-Port1000BASE-X10/100BASE-TX 10/100/1000BASE-TSpeed: (100Base-TX) Green = 100Mbps Yellow = 10Mbps (1000Base-X) Green = 1000Mbps Yellow = 10/100Mbps Duplex: Green = Full Duplex, Yellow = Half Duplex2625 25 263CR17561-91 SuperStack 3 Switch 4500 26-Port1000BASE-X10/100BASE-TX 10/100/1000BASE-TSpeed: (100Base-TX) Green = 100Mbps Yellow = 10Mbps (1000Base-X) Green = 1000Mbps Yellow = 10/100Mbps Duplex: Green = Full Duplex, Yellow = Half Duplex2625 25 263CR17562-91 SuperStack 3 Switch 4500 50-PortPWRRPSDuplex:Green = Full Duplex, Yellow = Half DuplexSpeed:Green = 100Mbps, Yellow = 10Mbps49 50 49 502252
