Viewing All Current End Hosts

The End Hosts Present table provides a complete list of all end host devices detected and successfully probed by the NetMRI appliance. You can begin by choosing Actions from the icon on the left of each table record. Other data displayed include the following:

• Action icon: Provides the Action menu with End Host History, Interface History, and Device History options, changing the Admin Status for an end host interface and editing the description and VLAN assignment.

• Host IP address: Provides a live link to the Device Viewer.

• Host Name: DNS host name (if any), provides live link to the Device Viewer.

• Host MAC: 48-bit hardware address of the host system.

• Last Seen: The timestamp of the last successful detection of the end host connected to the given switch interface. You can also choose to display the First Seen data column, which is the timestamp of the moment when the end host was first detected as a host connected to its current LAN switch interface.

• Device Name: The LAN switching device to which the host is currently associated (live link to the Device Viewer).

• Interface: The LAN switched interface to which the end host connects (live link to the Interface Viewer).

• If Oper Status: The LAN switched interface's operating status (live link to the Interface Viewer).

• VLAN Name: The active VLAN to which the end host is currently bound (live link to the VLAN Viewer).

For more insight into end host history, click the Device History icon at the top of the table for any end host page, and choose Period and a time span: Daily, Weekly, Monthly, 7-Day, or 30-Day. The host history adjusts its data set to reflect the different sampling, and in many cases shows a larger sampling of events in which the device was polled for more insight into end host history, changes were detected, such as connectivity, an end host disconnecting, an end host changing to another VLAN, and other events.
