HP 316095-B21 - StorageWorks Edge Switch 2/24 Примечание к выпуску - Страница 8

This feature is supported on all products except the Edge Switch 2/16 and Edge Switch

2/32. Predictive Optics Monitoring is not supported on the ﬁber port module (FPM) or

the ﬁrst revision of the universal port module (UPM) on the Director 2/64 or Director

2/140.

Support for this feature in the Edge Switch and Director management applications is

as follows:

•

CLI—Includes a new command to display overall optic health for ports that

support enhanced digital diagnostics, and a command that displays the overall

optic health, enhanced digital diagnostic data, and thresholds for a speciﬁc port.

•

HAFM—Displays events for ports that exceed threshold values.

•

HAFM Basic—The Port List page includes a Health Status column that displays the

status of the installed optical transceiver (Normal, Warning, Alarm, or No Info).

Clicking the status in the column displays the health status, port type, and port

number. If the port has a digital diagnostics (DD) enabled optical transceiver,

product ﬁrmware displays reported temperature, voltage, current, transceiver

power, and receiver power. Optical transceivers also provide vendor-speciﬁc

threshold values.

Interswitch Link (ISL) cost conﬁguration

ISL Cost Conﬁguration gives users more control over how FSPF routing is determined for

a switch. Cost is a metric assigned to ISLs by the product's Path Selection functionality to

determine the shortest path (or the path that takes the least amount of time for trafﬁc to

travel) to a destination. A path with a lower cost is considered faster than a path with a

higher cost. Conﬁguration is provided in HAFM Basic and CLI.

ISL Cost Conﬁguration gives advanced users more control over their fabric conﬁguration.

It allows them to establish all ISLs with equal cost factors, causing the switch not to

account for link speed when assigning ﬂows to ISLs.

•

CLI—The config.switch.islFSPFCost command conﬁgures the FSPF cost

of ISLs on the switch. When the islFSPFCostState command is set to ignore,

each ISL has the same FSPF cost; the actual FSPF cost is ignored. When set to

port, each ISL has a default cost, which depends on the speed of the port.

•

HAFM Basic—Includes an ISL FSPF Cost Conﬁguration ﬁeld on the Switch

Parameters page that allows users to conﬁgure FSPF cost of ISLs on the switch

By Port Speed or Ignore Port Speed.

• By Port Speed—When selected, the FSPF cost for each port depends on the

speed of the port. In this case, the cost is inversely proportional to the bit rate

of the ISL. The higher the bit rate, the lower the cost. The speed of the ISL is a

factor in determining the shortest path.

• Ignore Port Speed—When selected, every ISL on the switch has the same

FSPF cost. The number of hops is the primary factor in determining the

shortest path; the speed of the ISL is not considered.
