Prerequisites
Before provisioning DWDM frequency, the user
must configure the connector breakout and apply the DCO setting to the transceiver (as
described in
Provisioning the DWDM coherent optic). After the DCO
is enabled, and the physical optical transceiver is present in the front panel cage, the
optic transceiver data shows the optic DWDM details. The provisionable frequency range
is also displayed here with the
show port 1/1/c1 command (see the
"Model Number", "Fine Tune Range", "Fine Tune Resolu*", and "Supported Grids" fields
below). To initially provision the frequency or change what was previously configured,
the user must shut down or disable the 1/1/c1 connector before
provisioning.

About this task
This procedure describes how to provision the DWDM frequency.
Procedure
-
Configure the frequency using the following context.
By default, no frequency is configured. A frequency must be
provisioned. The following example displays a frequency configuration of
194400000:
Example configure port 1/1/c1 dwdm frequency 194400000 (classic
CLI)
*A:Dut-A# configure port 1/1/c1 dwdm frequency
- frequency <MHz>
- no frequency
<MHz> : [191100000..196150000]
*A:Dut-A# configure port 1/1/c1 dwdm frequency 194400000
Example configure port 1/1/c1 dwdm frequency 194400000
(MD-CLI)
*[pr:/configure port 1/1/c1 dwdm]
A:admin@cses-V27# frequency ?
frequency <number>
<number> - <191100000..196150000> - megahertz
Center frequency for tunable DWDM optical interface
*[pr:/configure port 1/1/c1 dwdm]
A:admin@cses-V27# frequency 194400000
-
Enable frequency by configuring either of the following:
- In the classic CLI, use the configure port
1/1/c1 no shutdown command to enable the connector.
- In the MD-CLI, use the configure port 1/1/c1
admin-state enable command to enable the connector.
Expected outcome In the following example, the “Config Freq” and “Oper
Freq” fields in the
show port 1/1/c1 output reflect the
frequency setting, the “Coherent Optical Module” values are present, and the
“Module State” displays the “txOff” value until the connector ports are
administratively set to
no shutdown or set to
enable. For any DWDM frequency changes, after port 1/1/c1
is administratively set to
no shutdown or set to
enable again, the coherent module initializes and
transitions through various states as visible in the “Module State”
field.

To the enable the laser and have the optic reach the “ready”
state, the connector port as per the configured breakout must be enabled.
Configure each connector port to be administratively set to no
shutdown or set to enable as follows:
- In the classic CLI, use the configure port
1/1/c1 no shutdown command to enable each connector
port.
- In the MD-CLI, use the configure port 1/1/c1
admin-state enable command to enable each connector port.
