The **Link** **Changes** page provides a list of interfaces that have most recently changed state. Data column defaults include the following (you may need to scroll across to see all data samples):

- **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). The Link Changes table is sorted by this column in ascending order.
- **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 switched interface's Admin status (whether the port is administratively enabled by the operator).
- **Line** **Speed**: The line speed of each listed interface.
- **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 in another device's ARP table, or otherwise saw the device on the network.
