Active Monitoring (ICMP ping) can be configured to monitor the device only rather than actively monitoring (pinging) all interfaces on a switch/device. 

If SNMP is causing the alarms, the events can be deferred under the Events View which will hide the event until the star changes. To defer an event, right-click on the event in the event manager and select Defer from the drop-down menu.

If you never want to get an event for an interface, then the mnemonic can be deleted via Edit Mnemonics. Select Configuration > Views > Edit Mnemonics from the control panel at the top of the page.
