SnmpEngineIdOrNone 4 SnmpEngineIdOrNone Syntax A specially formatted SnmpEngineID string for use with the Entity MIB. If an instance of an object with syntax SnmpEngineIdOrNone has a non-zero length, then the object encoding and semantics are defined by the SnmpEngineID textual convention (Refer to RFC 2571 [RFC2571]). If an instance of an object with syntax SnmpEngineIdOrNone contains a zero-length string, then no appropriate SnmpEngineID is associated with the logical entity (that is, SNMPv3 not supported). • For the Brocade 3016 or Brocade 4020 blades, the snmpEngineID takes the UUID value. For example, if the UUID value is A9914D56-1E5A-0E59-C51E-528802B06E4F, the snmpEngineID displays 80.00.06.34.B1.A9.91.4D.56.1E.5A.0E.59.C5.1E.52.88.02.B0.6E.4F (hex) • For other switches, the snmpEngineID takes the WWN. For example, if the WWN value is 10:00:00:05:1e:35:d5:ee, the snmpEngineID displays 80.00.06.34.B2.10.00.00.05.1E.35.D5.EE (hex) • If the WWN cannot be taken, the snmpEngineID takes the IP address + port number along with the private enterprise number and algorithm type used. An example of this type of snmpEngineID would be 00.00.06.34.00.00.00.A1.0A.20.93.CA (hex) OCTET STRING (SIZE(0..32)) Empty string or SnmpEngineID Entity MIB Objects The Entity MIB objects are divided into the following groups: •Physical Entity Group 460 •Logical Entity Group 480 •Entity Mapping Group 490 •General Group 500 The following sections list the MIBs in each group.
