Default command level
2: System level
Parameters
master: Adopts the internal clock as the clock source.
slave: Adopts the line clock as the clock source.
Usage guidelines
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 CT3 interface on another router, the local end
can use either clock, as long as it is different from the one adopted at the remote end.
Examples
# Use the internal clock as the clock source on CT3 interface T3 2/0/0.
<Sysname> system-view
[Sysname] controller t3 2/0/0
[Sysname-T3 2/0/0] clock master
