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.
