Alarm conditioning

Hi,

We are working with our customer and would like to know if it is possible to have some conditioning around 1 specific alarm we have. Let me explain a little bit the scenario.

Currently, the CMTS will trigger an "Operational Status link-aggregate 1" Down alarm whenever the "Operational Status ethernet 7/0" is Down as shown in the below image:

What we are looking for is to see if there is a way to set a condition so that the "Operational Status link-aggregate 1" Down alarm is triggered ONLY  if both ethernet ports are down: "Operational Status ethernet 7/0" and "Operational Status ethernet 6/0".

It would ideally look like this, having both alarms for ethernet 7/0 & ethernet 6/0 generating the link-agg 1 alarm. ( Please note that the following image is for representation purposes of the 2 alarms we would like to have in order to trigger the link-aggregate 1 alarm)

**********Edit**********
This is how the alarm template looks like for the interfaces:

Thanks in advance,

Carlos

Thank you very much for your responses Miguel and Michael. I ‘ve gone down both paths, alarm filter condition and correlation rule, but I have some questions around it. Instead of updating thi:

Hi Carlos,

When you take a look at the alarmtemplate of your element, you will see a column "Condition". Here you can set a condition to your parameter based on the value/severity of the other parameters.

Do note that when the condition you set is true the monitoring of the parameter where you have set the condition will be disabled.

Hi Michael,

Thanks for your response. So does this mean that in this case, for the condition that I want to get the link-aggregate 1 alarm triggered, if the “Operational Status ethernet 6/0” and “Operational status ethernet 7/0” is down (which would be True for the condition), the Operational Status link-aggregate 1 won’t be monitored? Or am I getting it wrong?

Thanks!

Hi Carlos,

This is indeed correct. I think your condition should look like :

Is Operational Status Ethernet 6/0 is not equal to Down
or Operational Status Ethernet 7/0 is not equal to Down

Only when both Operational Status Ethernet 6/0 and Operational Status 7/0 are Down the condition will be false and the Operational Status link-aggregate 1 parameter will be monitored.
