Summary
Use the SUMMARY screen to see the Switch’s front panel port status, connected ports information, networked AV information, used power for PoE devices, Nebula Cloud Control status, and a link to go to the IP Setup screen.
The SUMMARY screen displays when you log into the Switch in Networked AV mode.
The following table describes the labels in this screen.

Port Status
This chart displays the status of the Switch’s front panel ports with connection (Fiber, Copper, and Combo).
Networked AV Information
IP Setup
This link takes you to a screen where you can configure the IP address and subnet mask (necessary for Switch management) and set up to 64 IP routing domains.
IGMP-Snooping VLAN
This displays the ID number of the VLAN group upon which the Switch is to perform IGMP snooping.
IGMP-Snooping
This displays Active when IGMP snooping is enabled to forward group multicast traffic only to ports that are members of that group.
Otherwise, it is Inactive.
IGMP-Querier
This displays Active when the Switch is allowed to send IGMP General Query messages to the VLANs with the multicast hosts attached.
Otherwise, it is Inactive.
IP Interface
This displays the IP address of the Switch for it to be managed over the network.
Unknown Multicast
This displays the action to perform when the Switch receives an unknown multicast frame.
It displays Drop when the frames are discarded.
It displays Flooding when the frames are sent to all ports.
It displays Drop on VLAN when the frames are discarded on the specified VLANs.
Power Usage(W)
For PoE models.
This chart displays the used PoE Watts over the total number of Watts provided on this Switch.
Cloud Control Status
This displays the registration and connection status between the Switch and the NCC (Nebula Control Center).
Click NCC Discovery or the switch button to go to SYSTEM > Cloud Management > Cloud Management screen.
Port
This displays the port of this Switch.
Port Name
This displays the port description of this Switch.
Link Speed
This displays the speed (either 100M for 100 Mbps, 1G for 1 Gbps, or 10G for 10 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.
Bandwidth Usage (Tx)
Bandwidth Usage (Rx)
These display the percentage of bandwidth usage on this port as a percentage of the Link Speed.
IGMP Leave Mode
This displays Immediate when the Switch receives IGMP leave packets, the Switch will close the multicast stream immediately without any further action.
This displays Fast when the Switch will further generate a group specific query packet to all the receivers. This could prevent the traffic being cut if some receivers still want to receive the multicast stream.
This displays Normal when the Switch receives an IGMP leave message from a host on a port, it forwards the message to the multicast router. The multicast router then sends out an IGMP Group-Specific Query (GSQ) message to determine whether other hosts connected to the port should remain in the specific multicast group. The Switch forwards the query message to all hosts connected to the port and waits for IGMP reports from hosts to update the forwarding table for this port.
