IP Config for All Streams (Multi-Unicast)
Stream Name:
The unique name entered in Stage 1 that describes the stream.
Multicast
or
Destination IP Address:
Type the IP address for the WAN interface of the NetXpress
LX system at the other end of this stream.
Local UDP Port:
Type the local UDP port in ingress and egress stream packets. The local UDP port
number must be a multiple of 5 between 50000 and 65535, inclusive.
Remote UDP Port:
Type
the remote or peer’s UDP port for ingress and egress stream packets.
The
remote UDP port number must be a multiple of 5 between 50000 and 65535, inclusive.
CoS Priority:
Click the CoS level option that applies to all egress packets for the stream:
Low
,
Medium
,
Normal
, or
High
.
Normal
is default.
When the operational state of a receive stream changes to Down, the type of alarm created depends
on the CoS level selected here. A
Normal
or
High
prioritystream going down would create a major
alarm. A
Medium
level stream going down creates a minor alarm. A
Low
level stream going down
would not create any hardware alarm but would still contain an entry in the
Current Alarms
and
Alarm History
tables for logging, traps, and other information. You can change the severity of these
alarms on the

page.
Egress IP Pkts. TTL:
Type the value of the IP TTL (Time to Live, # of hops) to be used in egress
stream packets. The default is 64. This number is decremented once by every router that handles the
packet. Once this field reaches 0, the packet is discarded by the router and does not reach any other
systems.
ON-DEMAND:
For Site Redundancy, enable ON-DEMAND on any streams intended for communication
with the Backup Headend system, including those at the Backup Headend itself.
