How does NAV use snmp read and write communities when both are present ?

A very long subject, repeated here:

How does NAV use snmp read and write communities when both are present ?

Untill now, we have only used snmp read on our core boxes. We are going to deploy vlanAdmin on some core boxes, and thus we need to register snmp write communities for these. We'll use snmpview-functionality to control the permission for the snmp write community.

Will this affect the NAV data collection in any way, or does all collection use snmp read even with snmp write present?

(I think NAV uses snmp read, and that everything will work fine, I just have to check... )
