That field is in fact accessible, but because the is prefix is reserved in the parser for matching services, you have to use IsSnmpPrimary. From a real system just now:

admin@opennms()> filter "isSnmpPrimary = 'P'"
No matching nodes/interfaces for this rule.
admin@opennms()> filter "IsSnmpPrimary = 'P'"

nodeId=1 nodeLabel=localhost location=Default
	IpAddresses:
		127.0.0.1
admin@opennms()>

We should call out this oddity in the rule formats section of the configuration reference.
