SnmpEngineIdOrNone

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 (see 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
container (5) The physical entity class is capable of containing one ore more removable physical entities,
possibly of different types (such as a chassis slot or daughter-card holder). For example, each
(empty or full) slot in a chassis is modeled as a container. Note that all removable physical
entities should be modeled within a container entity, such as field-replaceable modules, fans,
or power supplies. Note that all known containers, including empty containers, should be
modeled by the agent.
powerSupply (6) The physical entity class is a power-supplying component.
fan (7) The physical entity class is a fan or other heat-reduction component.
sensor (8) The physical entity class is a sensor, such as a temperature sensor within a router chassis.
module (9) The physical entity class is a self-contained subsystem (such as a plug-in card or
daughter-card). If it is removable, then it should be modeled within a container entity;
otherwise, it should be modeled directly within another physical entity (for example, a chassis
or another module).
port (10) The physical entity class is a networking port, capable of receiving or transmitting networking
traffic.
stack (11) The physical entity class is a super-container (possibly virtual), intended to group together
multiple chassis entities (such as a stack of multiple chassis entities). A stack might be
realized by a virtual cable or a real interconnect cable attached to multiple chassis, or it can
comprise multiple interconnect cables. A stack should not be modeled within any other
physical entities, but a stack might be contained within another stack. Only chassis entities
should be contained within a stack.
