Viewing the Hub Locator

The Hub Locator table lists all switched interfaces in the network that operate as Smart Hubs, with more than one end host connected to the switch port. Consider the table in Switch Port Management, with its sortable # End Hosts column. When you perform the sort, all interfaces that show a count of more than one connected host in the # End Hosts column will appear at the top. These interfaces with their higher End Host counts will also be separated into the Hub Locator table.

In many cases, the collection of end hosts for each located hub are clients bound to a VLAN.

  • Action icon: Provides the Action menu with View Device History, Set Admin Status, Edit Description, and Topology Viewer options.

  • Device Name: The Ethernet switching device to which the interface is associated (live link to the Device Viewer, displaying the Issues page).

  • Interface: The switched port identifier (live link to the Interface Viewer, displays the History of the port).

  • Interface Type: The standard interface type supported by the port. For switched Ethernet, this value will typically be ethernet-csmacd.

  • Interface MAC: The 48-bit hardware address for each port in the Link Changes list (live link to the Interface Viewer, displays the History of the port).

  • If Oper Status: The switched interface's operating status.

  • If Admin Status: The switch port's Admin status (if the port is administratively enabled by the operator).

  • # End Hosts: The number of detected End Hosts bound to the hub interface (live link to the End Hosts Present page). The Hub Locator table is sorted in descending order by this column.

  • First Seen: The timestamp indicating when Switch Port Management first polled the device.

  • Last Seen: The timestamp indicating the last occasion when Switch Port Management detected the device on the network.
