This read-create TruthValue, defaulting to false, indicates whether a given SNMP target address is reachable over the OOBM interface; it only applies if the device has a physical OOBM port, and per the source is used for SNMP traps only. Admins set this to true when configuring an SNMP trap destination that should be reached via the dedicated OOBM interface rather than an in-band path. For example, an admin sets this to true(1) on a trap-receiver target address that is only reachable through the switch's out-of-band management network.
