Using SNMP to Manage the Switch
FcConnUnitGlobalId
(continued) FcGlobalId Switch WWN R Use of the IEEE formats allows any
IEEE-registered vendor to assure
global uniqueness independently. The
following are some references on IEEE
WWN formats:
http://standards.ieee.org/regauth/oui/tut
orials/fibreformat.html
http://standards.ieee.org/regauth/oui/tut
orials/fibrecomp_id.html
If one or more WWNs are associated
with the connectivity unit via other
management methods, one of them
SHOULD be used for
fcConnUnitGlobalId. If there is not a
WWN assigned specifically to the
connectivity unit, there is some merit,
though not a requirement, to using a
WWN assigned to (one of) its
permanently attached FC/LAN
interface(s). This can not risk
uniqueness, though. As a
counterexample, if your agent runs in a
host and the host has an HBA, it is
quite possible that agent, host, and
HBA will all be distinct connectivity
units, so the host and agent can not
use the WWN of the HBA. Another
example: If your hub has a built-in
Ethernet port, it might be reasonable for
the hub to use its LAN address
(prefixed with the appropriate NAA) as
its fcConnUnitId. But if the Ethernet
were a replaceable PCCard, the hub
should have an independent ID.
FcConnUnitType FcUnitType switch(4) R The type of this connectivity unit.
FcConnUnitNumports Unsigned32 Number of ports from
PROD_CNFG. R Number of physical ports in the
connectivity unit (internal/embedded,
external).
