SCF Commands for the SLSA Subsystem

ALTER LIF Command
Valid range: 1 to 200000 microseconds
Default value: If DATAFORWARDMODE is MANUAL, DATAFORWARDTIME
defaults to either 10 milliseconds or 10000 microseconds depending on the setting
of DATAFORWARDUNIT. If DATAFORWARDMODE is ADAPTIVE,
DATAFORWARDTIME defaults to 1 millisecond.
Considerations

An ALTER LIF command is accepted only when the LIF object is in the STOPPED
state.

You must specify at least one option.

An error is returned if a DATAFORWARDMODE of ADAPTIVE or a
DATAFORWARDUNIT of MICROSECONDS is specified for non-G4SA adapter
types.

When DATAFORWARDMODE is ADAPTIVE, the DATAFORWARDCOUNT and
DATAFORWARDTIME settings are used as upper limits. An error is returned if a
DATAFORWARDUNIT of MICROSECONDS is specified for non-G4SA adapter
types.

DATAFORWARDCOUNT and DATAFORWARDTIME are meaningful only when the
specified PIF is a part of an Ethernet 4 ServerNet adapter (E4SA), Fast Ethernet
ServerNet adapter (FESA), Gigabit Ethernet ServerNet adapter (GESA), Gigabit
Ethernet 4-port ServerNet adapter (G4SA), or Token Ring ServerNet adapter
(TRSA).

See Considerations When Using the DFC, DFM, and DFT Parameters on
page 4-26
Example
The following example changes the DATAFORWARDCOUNT (DFC) value for a
specified LIF.
ALTER LIF $ZZLAN.L11123A , DATAFORWARDCOUNT 5
The following example changes the data forward mode to ADAPTIVE to allow a G4SA
to choose the best DFC and DFT values depending on data-traffic:
ADD LIF $ZZLAN.L11123A, PIF G4SA.0.A, DATAFORWARDMODE
ADAPTIVE
The following example changes the data forward unit to have a wait time in
microseconds for a G4SA adapter:
ADD LIF $ZZLAN.L11123A, PIF G4SA.0.A, DATAFORWARDUNIT
MICROSECONDS
