Configuring switched point-to-point FICON
2
Sequence level switching 0 Do not change. When set to 1, frames of the same
sequence from a particular source are transmitted
together as a group. When set to 0, frames are
interleaved among multiple sequences when
transmitted. Under normal conditions, sequence-level
switching should be disabled for better performance.
Disable device probing 1 The recommended best practice is to disable device
probing. When disable device probing is set to 1,
devices that do not register with the Name Server will
not be present in the Name Server database.
Suppress Class F traffic 0 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 0 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 0 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 2-byte addressing.
Virtual Channel parameters No Do not change. The switch allows fine-tuning of a
specific application through virtual channels
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 No With Fabric OSv6.1.0 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.
NOTE: The default value is incorrectly shown as 0.
Login stage interval Do not change. Specifies the stage interval in the
staged F_Port login, in milliseconds.
Zoning operation parameters No Do not change. Disables and enables NodeName Zone
Checking.
