4
Memory Utilization — Indicates how much encoder memory is used, expressed in
percent.
5
AV LAN Utilization
— Indicates the total bandwidth usage at that moment. The
encoder generates an alarm if the utilization goes above 90%. The alarm clears
automatically once the level drops below 90%.

IGMP Querier pane
An IGMP querier is a network service, usually running on a network switch, that can initiate
IGMP queries. An IGMP querier should be configured on the NAV network. It manages the
multicast traffic. If there is no IGMP querier on the network, there is no effective multicast
traffic management and the multicast traffic saturates the network and stream and
communication errors can occur.
The
IGMP Querier
pane (see figure 38 ,
3
) shows whether or not an IGMP querying device
is present on the network, and the IP address of the IGMP querier. Figure 39 shows the
indication if no IGMP querier is present on the network.

Ethernet Extension Utilization pane (NAV E 501only)
The
Ethernet Extension Utilization
pane (see figure 38 ,
6
) indicates the total
bandwidth usage of the rear panel Extension port (see figure 2 ,
H
on page 5) at that
moment. The encoder generates an alarm if the utilization goes above 90%. The alarm
clears automatically once the level drops below 90%. Figure 40 shows the indication if the
Extension port is either
disabled (see Network Connection on page 49) or enabled with
no device connected to it.
