Specifying a line clock input port

Only main ports can be specified as line clock input ports. For the timing signal received on the line clock
input port to be used for synchronization, you must set the port to operate in slave mode.
To specify a line clock input port:
Step
1. Enter system view.
2. Enter interface view.
3. Set the clock mode to
slave.
4. Return to system view.
5. Specify the port as a
line clock input port.

Configuring the method to set the SSM quality level of a clock
source
The network clock monitoring module can use one of the following methods to assign an SSM quality
level to the timing signal from a clock source:
Uses the SSM quality level extracted from the received timing signal.
•
Uses the SSM quality level manually assigned as described in
•
a clock
For BITS and PTP, you must perform this task on the default MDC. For a line clock, you must perform this
task on the MDC that contains the clock input port.

In standalone mode:
network-clock source { bits0 | bits1 }
frequency { bps-2m | hz-2m }
In IRF mode:
network-clock chassis

By default, the frequency of a
BITS clock is 2 Mbps.
This command is configurable
only on the default MDC.
However, the command setting
takes effect on all MDCs.

N/A
By default, slave clock mode is enabled
on ports.
N/A
By default, no ports are configured as line
clock input ports.
