QOS warings - What is monitored

[loneWolf9]

So I am reading my logs from last night and see some more than usual QOS warning on switch.

After looking through forum and several Avaya (Nortel) docs I cannot seem to find a straight answer to the following questions.

With the QOS warnings, is it the ELAN or the TLAN (I am thinking ELAN)?

Does it just measure the connection between primary equipment, i.e. call server, sig servers, MG's etc?

Or

Does it include all equipment attached to the switch which would also included phones?

Thanks in advance for your input.


As usual the Avaya/Nortel docs are not much help so far.

The QoS warnings are triggered by conditions on the T-LAN relating to active Media Streams.

Latency, Jitter, Packet Loss and R-Value are the main things that are monitored. You can define upper and lower thresholds that will cause the Alarms to be triggered and cleared.

The elements involved are your Signaling Servers, Media Gateway Controllers, DSP Daughterboards, and IP phones (Any device which can participate in an IP call).

Thank you Allenmac for clearing this up for me.

QOS warnings are from the TLAN. The warning should identify the zone affected. Generally it is the phones and the VGMC's or DSP's, if I remember right. This is a good place to start:
NN43001-260_03.09_Fundamental's_DNVOIP.

You can actually increase or reduce the level of QOS logging in load 117.

CHG ZQNL <level>
Change the Notification Level for all zones, where:

level = 0-(2)-4, where:
- Level 0 = All voice quality alarms are suppressed.
- Level 1 = Allow zone-based Unacceptable alarms.
- Level 2 = Allow all level 1 alarms PLUS zone-based Warning
alarms.
- Level 3 = Allow all level 1 and 2 alarms PLUS per-call
Unacceptable alarms.
- Level 4 = Allow all level 1, 2, and 3 alarms PLUS per-call
Warning alarms.

Level 4 though generating more QOS alarms would give you more info on it.

Appericate the reference to the PDF.

Changing the level may happen at a later date. Right now I think I am going to have to do some data captures off the TLAN Vlan to make sure that there is only voice on it.
