IBM SC30-3681-08 LMI N2 error threshold, LMI N3 error threshold window, MIR % of CIR, Default CIR

Con®guring Frame Relay Interfaces

LMI N2 error threshold

Indicates the number of management event errors occurring within the N3 window that will cause a reset of the Frame Relay interface.

LMI N3 error threshold window

Indicates the number of monitored management events used to measure the N2 error threshold.

MIR % of CIR

Minimum IR, expressed as a percentage of CIR.

IR % Increment

Percentage by which the router increments the IR each time it receives a frame without BECN until it reaches the maximum IR.

IR % Decrement

Percentage by which the router decrements the IR each time it receives a frame that contains BECN until it reaches the minimum IR.

Default CIR

The committed information rate, in bits per second, used as the default for VCs on this interface.

Default Burst Size

The committed burst size, in bits, used as the default for VCs on this interface.

Default Excess Burst Size

The excess burst size, in bits, used as the default for VCs on this interface.

Maximum circuits allowable
	Indicates the number of PVCs and SVCs that can exist for this
	interface. This number includes any PVCs that you added with the
	add permanent-virtual-circuit command and any SVCs that you
	added with the add switched-virtual-circuit command and
	dynamically learned through the management interface.
Total PVCs con®gured
	Indicates the total number of currently con®gured PVCs that can
	exist for this interface.
