Syntax
clock { master | slave }
undo clock
View
ATM interface view
Parameter
master: Adopts the internal clock mode.
slave: Adopts the line clock mode.
Description
Using the clock command, you can set the clock mode on an ATM interface. Using
the undo clock command, you can restore the default clock mode on the
interface.
By default, the ATM interface adopts the slave clock.
When an ATM interface is working as DCE, choose the master clock mode. When
it is working as DTE, choose the slave clock mode for it. When ATM interfaces of
two routers are directly connected by fiber, one end should be configured with the
master clock mode and the other with the slave clock mode.
Example
Adopt the master clock on the ATM interface 4/0/0.
