e3 set clock

Use e3 set clock to set a clock mode for the E3 channel.

Syntax
e3 e3-number set clock { master | slave }
undo e3 e3-number set clock
Default
The clock mode of an E3 channel is slave.
Views

Default command level
2: System level
Parameters
e3-number: Number of an E3 channel on the CPOS interface, in the range of 1 to 3.
master: Sets the clock mode to master.
slave: Sets the clock mode to slave.
Usage guidelines
You can configure different clock modes for different E3 channels depending on the device each E3
channel is connected to. For example, when an E3 channel is connected to a SONET/SDH device, set
its clock mode to slave. When it is directly fiber-connected to a router, set different clock modes at the two
ends.
On a CPOS interface, the clock modes of E3 channels are independent of one another.
Configure the clock mode of an E3 channel the same as the global clock mode.
Examples
# Configure the clock mode of E3 channel 1 on interface CPOS 2/0/0 as master.
