I just started working with LMS 3.1. I'm getting alerts from some of the VLAN interfaces on our 6500 that they are not reachable. This is because of access lists on those particular VLANs. I don't need to monitor these particular VLANs. How can I remove them from polling? I can navigate to DFM - Configuration - Polling parameters and select the group but the options are not that granular. It seems like you have to poll all of interfaces or none of them. Is there are way to monitor only some of the interfaces?
Yes. To disable the pinging of certain IP addresses (or just unmanage entire interfaces) go to DFM > Device Management > Device Details. Launch the Detailed Device View on the desired device, and select either the IP or Interface node in the left-hand tree. If you unmanage just the IP address, then the DFM will still report OperationallyDown, utilization, etc. issues on the interface. It just won't ping that interface's IP address.
If you unmanage the interface, however, then DFM will not report any events for that interface.
