4.
Create a receive stream on the other NetXpress LX multiplexer (System B).
5.
Activate the new stream.
6.
On the
Stream Statistics
table, verify that
•
The System B stream is operating (
Op State
=
Up
).
•
Stream packets are being counted (
Rx Packet Count
).
•
There are no packets dropped (
Rx Packet Statistics Lost
and
Under
=
0
).
•
There is no excessive jitter; that is, the
Rx Queue Cur
and
Avg
should equal about half the
Jitter Buffer Value you configured for the stream. It is normal to vary +/-1 from the halfway
point. However, if either the current or average jitter statistic is near 64 or 0, it would indicate
excessive jitter.
Note:
It is best to create and activate a stream in the transmitter before creating and activating
streams in the receiver. If you activate the receive stream before first activating the transmit
stream, an alarm occurs.
If the receive stream is activated before the transmit stream, clear the alarm (Section 5.1.2)
and then follow the stream test process.
If you have problems creating or activating the stream, try the troubleshooting guidelines in Section
5.2.2.4. If there are dropped packets, use these guidelines to troubleshoot the difficulty:
●
Make sure cable connections for both multiplexers are secure.
●
Confirm that the network switches are properly configured: 100Base-T, full duplex is
recommended.
●
Confirm that the two systems are using proper timing modes.
●
Confirm that the network is not oversubscribed by the NetXpress LX system and other services.
