Blank lines have been added for clarity. The first step is to determine which trap caused this output. Looking after the words "NO TRAPD. CONF FMT FOR" you can see the numbers 1.3.6.1.2.1.8888.0.1 which identifies this as a switch SCN trap (from table in section 2.3). After the trap OID, the variable bindings are listed. HP OpenView calls them "ARGS" and shows how many have been found in this particular trap (in this case, 2). The first arg is identified by it's OID in symbolic form: mgmt.mib-2.fcMgmtMIB.fcMgmtObjects.fcMgmtConfig.fcConnUnit Table.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 the EFC Server, which uses a different numbering scheme for the unit-id than the E/OS 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 E/OS and EFCM: E/OS: WWN(8 numbers).0.0.0.0.0.0.0.0 EFCM: 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. 2-18 E/OS SNMP Support Manual
