Multicast TTL (Time-to-Live)
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.
Multicast TTL can be set to any value ranging from 1 to 255. The default setting is 5.
To set a multicast TTL value, use the web interface or SIMPL Windows.
Using the Web Interface
Configure multicast TTL by clicking the Settings tab and then clicking Stream. In the Advanced
section, set a multicast TTL value:
1. Disable Auto Initiation by setting the Auto Initiation toggle switch in the Off (left) position.
2. Stop the stream by clicking Stop.
3. Enable Custom TTL by setting the Custom TTL toggle switch in the On (right) position.
4. In the TTL text box, enter the desired TTL value (1 to 255). The default setting is 5.
5. Enable Auto Initiation by setting the Auto Initiation toggle switch in the On (right)
position. The stream automatically restarts.
NOTE:
Disabling Custom TTL returns the TTL value to the default setting.
