		errors. The range is 1 to 65535 frames.
		• Enter threshold high none to disable the high
		threshold.
		• Enter threshold low low-framesto set a low threshold
		in number of frames. The range is 0 to 65535. The
		default is 1.
		• Enter window milliseconds to set the a window and
		period of time during which frames with CRC errors
		are counted. The range is 10 to 1800 and represents the
		number of milliseconds in multiples of 100. The
		default is 100.

The ethernet oam link-monitor transmit-crc {threshold {high {high-framesnone} low

{low-frames}} window milliseconds} command is visible on the router and you are allowed to enter it, but it is not supported. Use the no form of this commands to disable the configuration. Use the no form of each command to disable the threshold setting.

Configuring Ethernet OAM Remote Failure Indications

You can configure an error-disable action to occur on an interface if one of the high thresholds is exceeded, if the remote link goes down, if the remote device is rebooted, if the remote device disables Ethernet OAM on the interface, or if the power failure occurs on the remote device .

Complete the following steps to enable Ethernet OAM remote-failure indication actions on an interface:

	Command		Purpose
Step 1
	configure terminal		Enter global configuration mode.
Step 2
	interface interface-id		Define an interface, and enter interface configuration
			mode.
