The FOXMAN-UN SNMP southbound interface supports SNMP v1, v2c and v3. All types of devices are depicted as SNMP devices in FOXMAN-UN (no type distinction made). Devices are tested for v3, v2c, and v1, in that order when SNMP security profile is set to “auto” in the FOXMAN-UN. The first positive answer is used to identify the (version of the) device. This means that for devices with multiple version support, a failed initial v3 call due to, say, wrong security settings will possibly identify that device as v2c or v1. V1/v2c community strings are supported; only the read community is relevant though, as no write access is as yet implemented. V3 User-based Security Model (USM) is supported; it should be noted, however, that the agent manager has one USM table. Devices must therefore not have matching security names with differing configurations. V3 View-based Access Control (VAC) is not supported at the moment.
