AT M O C - 3 C/STM-1 INTERFACE
CONFIGURATION COMMANDS
clock
Syntax clock { master | slave }
undo clock
View ATM OC-3c interface view, STM-1 interface view
Parameter master: Sets the clock mode as master.
slave: Sets the clock mode as slave.
Description Use the
clock command to set the clock mode for an ATM OC-3c/STM-1
interface.
Use the
undo clock command to restore the default, that is, the slave 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.
Example # Set the clock mode of ATM interface 5/0 to master.
<Sysname> system-view
[Sysname] interface atm 5/0
[Sysname-Atm5/0] clock master
frame-format
Syntax frame-format { sdh | sonet }
undo frame-format
View ATM OC-3c interface view, STM-1 interface view
Parameter sdh: Sets the framing format to SDH STM-1, the synchronous transport
module-level 1 (STM-1) of synchronous digital hierarchy (SDH).
