NNMi Disable subnet discovery for Juniper clustering

We have some Juniper SRX chassis where the internal EM clustering interfaces are using extremely broad subnets (10.0.0.0/8 and 128.0.0.0/2). The interfaces themselves are disabled as we do not have these in a cluster but they still have IP addresses in these 2 ranges which is creating some unwelcome subnets in the NNMi subnet inventory.

Is there a way to disable a subnet from being discovered/added to the inventory?

Has anyone else had this problem? How did you work around it?

Re: NNMi Disable subnet discovery for Juniper clustering

Hello Nick,

 

I hope you are doing great.

 

In regards with your technical question, for this I would recommend to create a discovery exclusion rule in Discovery> Discovery Configuration> Subnet Connection Rules.

I hope this informaion will so helpful to you.

Best Regards.

Re: NNMi Disable subnet discovery for Juniper clustering

Unfortunatly this doesnt seem to work as the subnet is a /2 or /8, with subnet connection rules a /28 or smaller is required for the configuration.
