88.4 MONITOR
The following sections introduce the MONITOR screens.
88.5 What You Can Do
• Use the System Information screen ( Section 88.6 on page 694 ) to check the firmware version number
and monitor the Switch temperature.
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.
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 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, 2.5G for 2.5 Gbps, 5G for 5
Gbps, or 10G for 10 Gbps) and the duplex ( F for full duplex or H for half). It also shows the cable
type ( Copper or Fiber ) for the combo ports. 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.
