PATHTF n
where framesize is the configured frame size, in words, as specified by the
FRAMESIZE modifier. If n is not greater than the result of this equation,
PATHPACKETBYTES will be set to zero, the variable packet size feature will be
permanently disabled, and an operator message will be logged.
To enable the PATHPACKETBYTES modifier, the setting must be greater than or equal
to 1024. If the PATHPACKETBYTES modifier was set to a value less than 1024, but
greater than 0, it is automatically changed to 1024.
If both the PATHBLOCKBYTES and PATHPACKETBYTES modifiers are enabled, the
PATHBLOCKBYTES modifier must be greater than or equal to the
PATHPACKETBYTES modifier value. If the PATHBLOCKBYTES modifier value is less
than the PATHPACKETBYTES modifier value, the PATHBLOCKBYTES modifier value
automatically changes to the PATHPACKETBYTES modifier value.
A value of 0 specifies that the variable packet size feature will be disabled.
A value of 9152 is recommended for Expand-over-ATM lines.
PATHTF n
Default: 0 (unset)
Units: Not applicable
Range: 0 through 186
The PATHTF has a range of 0 to 186 to designate the time factor in selecting the best
path to other nodes. A smaller number indicates a more desirable path for routing. If
you set PATHTF, it overrides any other parameter (RSIZE, SPEED, SPEEDK, or
LINETF) in calculating the time factor for the path.
When PATHTF is set for a multi-line path, the line state and number of lines in the path
are ignored and the PATHTF setting is a constant value assigned to the time factor for
the path.
If PATHTF is left unset (a zero value), this p
arameter is not used in setting the time
factor. Either RSIZE, SPEED, SPEEDK, LINETF, or PATHTF must be set, else the line
handler will display a configuration error. For more information on establishing time
factors, see
Setting Time Factors on page 17-23.
PROGRAM n
Default: $SYSTEM.CSSnn.C1097P00 for direct-connect lines
$SYSTEM.CSSnn.C1098P00 for satellite-connect lines
Units: Not applicable
Range: Not applicable
This modifier is applicable to direct-connect and satellite-connect Expand line-handler
processes only. This modifier identifies the specific microcode file where the data link
control (DLC) task is located. The microcode file is downloaded to the ServerNet wide
area network (SWAN) concentrator communications line interface processor (CLIP)
