Looking at an SNMP walk over ( on a CISCO FC switch, I'm seeing results of the form:

'[23].y' => '0xWWN',

Through some walking, I've determined that x is the switch port identifier used, for example, in My question is: what are the [23] and y?

A full walk shows that y is only used in the fcIfFLoginTable, but I'd still like to know its significance, as it appears unique.

Did you check the MIB ? – kls Mar 7 '12 at 20:36
yes. what i know comes from a mixture of cisco's lookup service, snmp walking, and reading through their mibs. everything after ..5.1.3 is not documented. – Christopher Neylan Mar 7 '12 at 21:26
