IBM SC30-3681-08 manual Idle ¯ag or mark, Ir-adjustmentincrement-% decrement-% minimum-IR

Con®guring Frame Relay Interfaces

APPN	58 bytes (see note)
	Note: Assumes worst case for APPN BAN where a T/R MAC address
	header and LLC header are added in addition to the FR header
	bytes.
	If FR data encryption is enabled then you must subtract up to an additional
	12 bytes.
	When using Frame Relay SVCs, the maximum information ®eld size must
	be the same at both ends of the virtual circuit. To determine the maximum
	information ®eld size, subtract 16 bytes from the frame size if encryption is
	enabled on the SVC and subtract 4 bytes if encryption is not enabled on
	the SVC.
idle [¯ag or mark]
	Sets the transmit idle state for HDLC framing. The default value is ¯ag,
	which provides continuous ¯ags (7E hex) between frames. The mark option
	puts the line in a marking state (OFF, 1) between frames. Mark idle causes
	the transmit LED to be dark between frames. Flag idle partially lights the
	transmit LED between frames.
ir-adjustmentincrement-% decrement-% minimum-IR
	Sets the minimum information rate (IR) and the percentages for
	incrementing and decrementing the IR in response to network congestion.
	The minimum IR, expressed as a percentage of CIR, is the lower limit of
	the information rate. The minimum percentage is 1 and the maximum
	percentage is 100. The default is 25.
	When network congestion clears, the information rate is gradually
	incremented by the IR adjustment increment percentage until the maximum
	information rate is reached. The minimum percentage is 1 and the
	maximum percentage is 100. The default is 12.
	When network congestion occurs, the information rate is decremented by
	the IR adjustment decrement percentage each time a frame containing
	BECN is received until the minimum information rate is reached. The
	minimum percentage is 1, and the maximum percentage is 100. The default
	is 25.

Example:

set ir-adjustment

IR adjustment % increment [12]?

IR adjustment % decrement [25]?

Minimum IR as % of CIR [25]?

line-speed rate

For internal clocking, this command speci®es the speed of the transmit and receive clock lines. The range is 2400 to 2 048 000 bps.

For external clocking, this command does not affect the hardware (in other words, the actual speed of the line) but it sets the speed of some protocols, such as IPX, used to determine routing cost parameters. Congestion monitoring also uses the con®gured line speed to determine the maximum information rate. Therefore, it is recommended that you set the speed to match the actual line speed. If the speed is not con®gured, the protocols and congestion monitoring assume a speed of 1 000 000 bps.

Notes:

1.When using external clocking, the maximum line speed is 6 312 000.

2.When using internal clocking, the maximum line speed is 2 048 000.
