Viewing the List of Changed Devices

The Changed Devices page lists any network devices that have changed in some fashion within the most recent polling time period. All newly discovered devices appear in this table. Devices may move from one VLAN to another VLAN and also appear here. If a device is previously administratively Up but is taken down for any reason, it also appears here. The devices listed here represent a smaller subset of the total of network devices, and the Capacity Summary – Ports panel changes values to match.

Default data sets shown in the table include the following:

  • Action icon: Provides the Action menu with View Device History, Open Telnet Session, Open SSH Session, and Topology Viewer options.

  • Device Name: The configured name of the network device.

  • IP Address: The host IP address of the network device (live link to the Device Viewer).

  • DNS Name: The DNS-resolved host name, if any, of the network device.

  • Last Seen: The timestamp of the last time the device was detected or seen on the network by any means, such as through a device's ARP table.

  • Last Changed: The timestamp of the last change performed on the device. This column is the default sorting for the Changed Devices table, listing in descending order from the most recent to the least recent.

Clicking on the IP address hyperlink for any device in the table displays the Device Viewer.
