Frame-Format - HP 6600 Command Reference Manual

Syntax
clock { master | slave }
undo clock
Default
The clock mode is slave.
Views
ATM OC-3c interface view, ATM STM- 1 interface view
Default command level
2: System level
Parameters
master: Sets the clock mode as master.
slave: Sets the clock mode as slave.
Usage guidelines
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.
Examples
# Set the clock mode of ATM interface 5/1/0 to master.
<Sysname> system-view
[Sysname] interface atm 5/1/0
[Sysname-Atm5/1/0] clock master

frame-format

Use frame-format to set the framing format for an ATM OC-3c/STM- 1 interface.
