Overlapping IP addresses
This might be an oldie...
How should we manage devices which have multiple overlapping IP addresses. For example Layer3 switches or router HA pairs can have same IP addresses set up to two or multiple devices for routing high availability or management reasons. This then makes SL1 see same IP addresses in multiple devices. And that then generates events into System organization, events like:
A Message Collector is managing multiple devices with an overlapping secondary IP address: Secondary IP address overlap on devices managed by Message Collector: 101 | Collector Groups: 44 | IP Address: 128.0.0.127 | Device IDs: 70999, 70998, 71001, 71009, 71005, 71003, 71006, 71004, 71007, 71002, 71013, 71012, 71015, 71010, 71014, 71008, 71016
Ok, that IP address can be deleted from database, but the nightly discovery again brings up the same issue next day. And because those are network devices where every now and then are some changes done in interfaces I believe we just have to have the Auto-Update enabled for those devices.
So:
- is there a way to tell that please do not discover all IP addresses for this device
- is there a way to make SL1 accept that, some other way than creating pretty interesting regexes into event policies
- event policy is for system level so that not easily be just suppressed for some devices
- are there some other ideas how to manage this situation
