llc2 modulo

Syntax	llc2 modulo { 8 128 }
	undo llc2 modulo
View	Ethernet interface view
Parameter	8: Specifies the modulus value to be 8.
	128: Specifies the modulus value to be 128.
Description	Use the llc2 modulo command to configure the modulus of LLC2.
	Use the undo llc2 modulo command to restore the default modulus of LLC2.
	By default, the modulus of LLC2 is 128.
	LLC2, like X.25, uses modulus to number frames. All frames sent are numbered
	incrementally and await an acknowledgment. When the frame number reaches
	the configured value (referred to as “modulus value”), subsequent frames are
	numbered from 1 again. For example, if the modulus value is set to 8, frames are
	numbered ...4, 5, 6, 7, 0, 1, ...
	LLC2 supports two modulus values: 8 or 128. 128 is usually used for Ethernet
	frames.
Example	# Set the modulus value for LLC2 frames to 8 on Ethernet 1/0.
