l
Discovery Agent: By default, Discovery Agent is enabled (the toggle switch is set in the On
position). When enabled, DM NVX encoders can be discovered for subscription to a
decoder in order to stream video and audio. The encoders are listed in the Available
Streams list in the
section of the Settings tab.
To disable Discovery Agent for reasons such as security, set the toggle switch in the Off
position.
l
Custom TTL: Multicast TTL provides the ability to limit or extend the hop limit of a DM
NVX stream that traverses routers. In IPv4 multicasting, routers have a TTL threshold
assigned to each interface. Only multicast packets with a TTL greater than the threshold
of the interface are forwarded.
The default multicast TTL setting is 5. To assign a different value:
1. Select the Custom TTL check box.
2. In the TTL scrollable text box, enter or select the desired value. Valid values range
from 1 to 255.
NOTE:
Deselecting the Custom TTL check box returns the TTL value to 5, which is the
default setting.
