1. IP addresses for authorized Trap Managers if you want management stations to receive trap messages generated by the hub Note If you do not have this information you might need to get it from your system administrator or from your network plan before you can complete your hub configuration Hub ID Numbers This section describes how to determine the hub ID number of a particular Micro Hub in a stack of Micro Hubs Before configuring the hub you should understand how hubs in a stack are identified You cannot manually assign a hub ID number to a hub in a stack The hub ID number is assigned based on how the hubs are cabled together Note The physical location of a hub in a stack does not determine a hub s ID number 3 6 Cisco Micro Hub User Guide Hub ID Numbers Here are two rules that determine hub ID numbers in a stack of hubs 1 The lowest hub ID number in a stack 1 is always assigned to the hub with another hub connected to its OUT port and with no hub connected to its IN port 2 The highest hub ID number in a stack any number from 2 to 5 is always assigned to the hub with no hub connected to its OUT port and with another hub connected to its IN port Figure 3 1 illustrates these rules Figure 3 1 Hub ID Numbers for Stacked Hubs 1000 Hub ID 1 T Hub ID 3 Hub ID 2 Hub ID 22.
