STEP 1: First check what the current expected power on the given section mux ccs-instance:
show ccs-instance <SECTION-MUX-PFG>
Example:
CDC_EAST_65R4_0001# show ccs-instance PFG-1-SECTION-MUX
ccs-instance:
- name : PFG-1-SECTION-MUX
channel-controller:

Here we can see the expected power is 0.87.
We know that the actual input power is supposed to be lower, and that the current measured power is accurate.
THIS IS IMPORTANT TO KNOW BEFORE PROCEEDING ANY FURTHER.
If the measured power is not what we expect, then that should be remedied first.
STEP 2: Next check what the input port is for the channel in question with the following command and its input power.
show ccs-instance <CHANNEL-MUX-PFG>
Example:
CDC_EAST_65R4_0001# show ccs-instance PFG-5-CHANNEL-MUX-MUX1
ccs-instance:
- name : PFG-5-CHANNEL-MUX-MUX1
channel-controller:
- center-frequency : 193250.000
spectral-width : 59.000
nmc-instance : ciena-6500r-slots:slots 5 config link '2 113' mc CCMDMUX-193250.0-s5p2 nmc CDC-CH1-193250.0

Example of checking input power (port 2):

STEP 3: Check the current power profile for the CCMD input port.
To confirm what the port-subport name should be, you can use the following commands:
display table
show slots <slot#> config pwr-profile
Example:
CDC_EAST_65R4_0001# show slots 5 config pwr-profile
slots config pwr-profile

show slots 5 config pwr-profile <port,BAND-C>
Example:
CDC_EAST_65R4_0001# show slots 5 config pwr-profile 2,BAND-C
slots:
- name : 5
config:
pwr-profile:
- parent-port : 2
- name : BAND-C

freq-min : 191268.750
freq-max : 196156.250

bin-spacing : 4887.500
reference-bandwidth : 12.500
target:
power:
- i : 1
p : -12.50
Note the current power values set for the bins.
In the above example you can see we have one bin at -12.5db.
We expect this value to drop after we regenerate the power profile.
STEP 4: Regenerate the pwr-profile for the specific CCMD input port.
As mentioned, only perform this if you are certain that the input power is correct and being received correctly by the RLA.
generate-pwr-profile instance "slots # config pwr-profile port,BAND-C"
Example of regenerating pwr-profile:
generate-pwr-profile instance "slots 5 config pwr-profile 2,BAND-C"
instance : ciena-6500r-pwr-profile:generate-pwr-profile
error : error-confirmation-required
error-str : This action may affect service
Confirmation required. Confirm? Y/N Y
status : ok
STEP 5: Check the pwr-profile for the new value and the section mux ccs-instance expected power values:
In the example below, we can see the power value has decreased as expected to -17.55db.
CDC_EAST_65R4_0001# show slots 5 config pwr-profile 2,BAND-C
slots:
- name : 5
config:
pwr-profile:
- parent-port : 2
- name : BAND-C
state : operational
freq-min : 191268.750
freq-max : 196156.250
bin-size : 4887.500
bin-spacing : 4887.500
reference-bandwidth : 12.500
target:

total-power : -17.55
tilt : 0.0
total-pwr-delta-threshold : 2.0

Subequently the expected input power value has updated:
