Clock and Data Recovery (CDR) is a process that is dependent upon a clock signal synchronous with the data flow. When a data flow arrives at the receiver, it is sent without additional clocking information, the receiver generates a clock from an approximate frequency reference, and then phase-aligns the clock to the transitions in the data flow with a phase-locked loop (PLL). Data distortion, noise, and jitter on the incoming data can be reduced if the CDR technology is used for data recovery from the transmission channel.
Use the following command to disable or enable the CDR function.
set interface gigabit-ethernet <interface-name> cdr [true | false]
The default setting is true. The command takes effect immediately after committing.
Enable the CDR function on interface te-1/1/49.
Disable the CDR function on interface te-1/1/49.
