SNMP::V3::Message

Inherits SNMP::Message / Reference / Object

Constants

MAX_MESSAGE_SIZE = 65507

Largest UDP payload (65535 - 20-byte IP - 8-byte UDP header) — advertised as msgMaxSize, the biggest response this engine will accept.

MSG_MAX_SIZE = ASN1::BER.new.set_integer(MAX_MESSAGE_SIZE)

MSG_VERSION = ASN1::BER.new.set_integer(Version::V3.to_i)

PRIVNONE = ASN1::BER.new.set_string("", tag: UniversalTags::OctetString)

Constructors

Instance methods

community=(id)

Mirrors engine_id= — see the note above; kept for SNMP::Message compatibility.

Source

engine_id

In SNMPv3 the authoritative engine id plays the role the community string plays in v1/v2c. engine_id is the meaningful accessor here; the inherited community field is kept in sync only so code shared with SNMP::Message (which reads #community) keeps working — prefer engine_id in v3 code.
