Cisco ASR 9000 Series User Manual

PurposeCommand or Action
• exact ql—Specifies the exact QL to send, unless DNU would
otherwise be sent.
Example:
RP/0/RSP0/CPU0:router(config-clk-freqsync)#
quality transmit
highest itu-t option 1 prc
• highest ql—Specifies an upper limit on the QL to be sent. If the
selected source has a higher QL than the QL specified here, this
QL is sent instead.
• lowest ql—Specifies a lower limit on the QL to be sent. If the
selected source has a lower QL than the QL specified here, DNU
is sent instead.
The quality option specified in this command must match the
globally-configured quality option in the quality itu-t option
command.
For clock interfaces that do not support SSM, only the lowest
QL can be specified. In this case, rather than sending DNU,
the output is squelched, and no signal is sent.
Note
(Optional) Adjusts the QL value that is received in SSMs, before it is
used in the selection algorithm.

Example:
RP/0/RSP0/CPU0:router(config-clk-freqsync)#
quality receive
highest itu-t option 1 prc
• exact ql—Specifies the exact QL regardless of the value received,
unless the received value is DNU.
• highest ql—Specifies an upper limit on the received QL. If the
received value is higher than this specified QL, this QL is used
instead.
• lowest ql—Specifies a lower limit on the received QL. If the
received value is lower than this specified QL, DNU is used
instead.
The quality option specified in this command must match the
globally-configured quality option in the quality itu-t option
command.
For clock interfaces that do not support SSM, only the exact
QL can be specified.

When you issue the end command, the system prompts you to
commit changes:
Uncommitted changes found, commit them
before exiting(yes/no/cancel)? [cancel]:
•
commit
Example:
RP/0/RSP0/CPU0:router(config-if-freqsync)#
end
◦
Entering yes saves configuration changes to the running
configuration file, exits the configuration session, and
returns the router to EXEC mode.
