Why each option
In FortiOS, for a UDP session, `proto_state` 00 typically signifies the initial, unestablished state, while 01 indicates an established session.
`proto_state=00` in FortiOS session output signifies the initial state of a UDP session when the first packet is seen and a session is being created.
`11` is not a standard or documented `proto_state` value for UDP sessions in FortiOS.
`proto_state=01` indicates an established UDP session in FortiOS, meaning the session entry has been created and subsequent packets are matching this session.
`05` is not a standard or documented `proto_state` value for UDP sessions in FortiOS.
