ATM OC-3c interface view, STM-1 interface view
master: Sets the clock mode as master.
slave: Sets the clock mode as slave.
Use the command to set the clock mode for an ATM OC-3c/STM-1
clock
interface.
Use the command to restore the default, that is, the slave clock
undo clock
mode.
When the ATM interface is operating as DCE, set its clock mode to master. When
the interface is operating as DTE, set its clock mode to slave.
When the ATM interfaces on two routers are connected directly through a
fiber-optic cable, set the clock mode to master at one end and to slave at the other
end.
# Set the clock mode of ATM interface 5/0 to master.
