SnmpEngineIdOrNone

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)

Syntax OCTET STRING (SIZE(0..32)) Empty string or SnmpEngineID
