clock (CE3 interface view)

Syntax	clock { master slave }
	undo clock
View	CE3 interface view
Parameter	master: Adopts the internal clock as the clock source.
	slave: Adopts the line clock as the clock source.
Description	Use the clock command to configure clock source for the CE3 interface.
	Use the undo clock command to restore the default, that is, line clock.
	The clock source is selected depending on the connected remote device. If
	connected to a transmission device, the local end uses the line clock. If connected
	to a CE3 interface on another router, the local end can use whichever clock so
	long as it is different from the one adopted at the remote end.
Example	# Use the internal clock as the clock source on CE3 interface E3 2/0.
	<Sysname> system-view
	[Sysname] controller e3 2/0
	[Sysname-E3 2/0] clock master
