Index connUnitId
connUnitId
OID 1.3.6.1.3.94.1.6.1.1
Description The unique identification for this connectivity unit among those within this proxy
domain. The value must be unique within the proxy domain because it is the index
variable for connUnitTable. The value assigned to a given connectivity unit should be
persistent across agent and unit resets. It should be the same as connUnitGlobalId if
connUnitGlobalId is known and stable.
Note The Brocade implementation maps the switch WWN to the top 8 octets of this
variable and sets the remaining lower 8 octets to 0.
To specify a particular instance of any columnar variable in the connUnitEntry (such
as connUnitType), specify the instance identifier as a 16-octet value.
Example:
connUnitType.10.0.0.60.69.4.11.19.0.0.0.0.0.0.0.0
where the object instance identifier consists of 16 octets, each representing the byte
value from high-byte order to low-byte order of this 128-bit integer.
connUnitGlobalId
OID 1.3.6.1.3.94.1.6.1.2
Description An optional global-scope identifier for this connectivity unit. It must be a WWN for
this connectivity unit or 16 octets of value 0.
The following characteristics are required:
• WWN formats requiring fewer than 16 octets must be extended to 16 octets with trailing 0
octets.
• If a WWN is used for connUnitId, the same WWN must be used for connUnitGlobalId.
When a non-zero value is provided, the following characteristics are strongly
recommended:
• It should be persistent across agent and unit resets.
• It should be globally unique.
• It should be one of these FC-PH/PH3 formats:
- IEEE (NAA=1)
- IEEE Extended (NAA=2)
- IEEE Registered (NAA=5)
- IEEE Registered extended (NAA=6)
Use of the IEEE formats allows any IEEE-registered vendor to assure global
uniqueness independently. The following are some references on IEEE WWN
formats:
