33SNMP Reference for Directors and Edge Switches
The first ARG is identified by it’s OID in symbolic form:
mgmt.mib-2.fcMgmtMIB.fcMgmtObjects.fcMgmtConfig.fcConn
UnitTable.fcConnUnitEntry.fcConnUnitStatus.
The numbers following fcConnUnitStatus are the unit-id which identifies a
particular switch in a fabric. (The unit-id is the first index for all tables in the Fibre
Alliance MIB). In this case, these traps are most likely from HAFM, which uses a
different numbering scheme for the unit-id than the EOS firmware (see below). In
both cases the unit-id is a string of 16 numbers. Following the unit-id is the actual
value of the first variable: ok. The value transmitted in the trap is numeric (an
integer) but HP OpenView has cross-referenced this numeric value with the MIB
definitions to provide the symbolic form (ok). The second variable binding is
fcConnUnitState and has the same indexing scheme for unit-id.
Numbering scheme for unit-id (fcConnUnitId) for EOS and HAFM:
EOS: WWN(8 numbers).0.0.0.0.0.0.0.0
HAFM: product-code.product-id.0.0.0.0.0.0.0.0.0.0.0.0.0.0
In both cases the total length is 16 numbers.
This identifier is used as the first index in all FA MIB tables.
