The following table describes the labels in this screen.
Label | Description |
|---|---|
Search ports | Enter a keyword to filter the list of ports or devices. |
N switch ports | This shows the number of Nebula Device ports (N) in the list. |
 | This shows the number of connected PDs that did not respond to an automatic PD alive check. |
 | This shows the number of ONVIF-compatible IP camera devices connected to Nebula Devices in the site. |
 | This shows the number of ONVIF-compatible NVR devices connected to Nebula Devices in the site. |
 | This shows the number of connected devices that did not respond to an ONVIF discovery query, or are of an unknown type. |
Switch/Port | This shows the port number of the Nebula Device. |
Port name | This shows the port description on the Nebula Device. |
PD health | This shows the status of auto PD recovery on this port. • Red: The Nebula Device failed to get information from the PD connected to the port using LLDP, or the connected PD did not respond to the Nebula Device’s ping requests. • Yellow: The Nebula Device is restarting the connected PD by turning the power off and turning it on again. • Green: The Nebula Device successfully discovered the connected PD using LLDP or ping. • --: Auto PD Recovery is not enabled on the Nebula Device and/or the port, or the switch is not supplying power to the connected PD.  For details on configuring auto PD recovery on a port, see Switch Ports. |
Link speed | This shows the speed (either 10M for 10 Mbps, 100M for 100 Mbps, or 1G for 1 Gbps) and the duplex (F for full duplex or H for half). This field displays Down if the port is not connected to any device. |
PoE draw(W) | This shows the total power that the connected PD draws from the port, in watts. This allows you to plan and use within the power budget of the Nebula Device. |
Bandwidth (Kbps) | Tx shows the number of kilobytes per second transmitted on this port. Rx shows the number of kilobytes per second received on this port. |
CRC | This shows the number of packets received with CRC (Cyclic Redundant Check) errors. |
Extended range | This shows whether extended range is enabled on the port. |
Device type | This shows the device type of the PD, as reported by ONVIF discovery. |
System name | This shows the name of the connected PD, as reported by ONVIF or LLDP. |
IP | This shows the IP address of the connected PD, as reported by ONVIF or LLDP. |
Discovered devices | This shows how many devices are connected to the port. Click the number to go to the Surveillance Port Details screen. |
