FICON switch parameters (Continued)

TABLE 2

Parameter

Response Comment

Suppress Class F
traffic

Do not change. By default, the switch can send Class F frames. When
this option is turned on (set to 1), Class F traffic is converted to Class 2
traffic before being transmitted to support remote fabrics that involve ATM
gateways.

Per-frame route
priority

Do not change. In addition to the virtual channels used in frame routing
priority, when this value is set to 1, support is also available for per-frame-
based prioritization.

Long-distance
fabric

Do not change. The recommended best practice is to configure individual
ports for long distance when cascading at extended distances.

Insistent Domain
ID Mode

Yes

The recommended best practice is to set the domain ID to be insistent.
Setting the insistent domain ID is required for two-byte addressing.

High Integrity
Fabric Mode

Before setting HIF mode, the following attributes must be configured:

•

An insistent domain ID (IDID

•

A Fabric Wide Consistency Policy => SCC:S (Strict mode)

•

A valid SCC_Policy (configured and activated)

Setting HIF mode locks the IDID, fabric wide consistency policy, and SCC
policy settings to ensure that the fabric is of high integrity so that it can
connect with the FICON channel. You cannot change these settings
without disabling HIF mode.

Virtual Channel
parameters

Do not change. The switch allows fine-tuning of a specific application
through virtual channel parameters. The default virtual channel settings
have already been optimized for switch performance. Changing these
values can improve switch performance, but can also degrade
performance.

F-Port login
parameters

With Fabric OS v6.1.0 and later, it is not necessary to make any changes
to F_Port login parameters. The only other reason to answer yes (y) to this
prompt is if NPIV is being used and there is a need to change the default
number of NPIV logins.

Maximum logins
per switch

Change this only if NPIV is being used and the number of fabric logins will
exceed the default or there is a need to limit the number of logins.

Maximum logins
per port

Change this only if NPIV is being used and the number of port logins will
exceed the default or there is a need to limit the number of logins.

Maximum logins
per second

For Fabric OS v6.1.0b and later - Do not change. Leave at default.

Do not change. Specifies the stage interval in the staged F_Port login, in
milliseconds.

Zoning operation
parameters

Do not change. Disables and enables NodeName Zone Checking.
