Slice and Port Numbering
The slices are numbered from 0 to 3. The ports are numbered across the different slices from 0 to 27. The port numbers against blue background represent client ports; port numbers against green background represent trunk ports.
Supported Configurations
The following configurations are supported on client and trunk ports in each slice. Each slice contains up to twenty Ethernet client ports operating at 10G, or five Ethernet client ports operating at 100G, or five Ethernet client ports operating at 40G. The client ports map to two trunk ports operating at 100G, 200G, or 250G that provides muxponder functionality.
40G client ports are supported from R6.0.1.

All configurations can be accomplished using appropriate values for client bitrate and trunk bitrate parameters of the hw-module command.
Configure the Slice
You can configure the slice with traffic on client and trunk ports. Both the trunk ports are always set with the same FEC mode. The slice can be configured to send encrypted traffic from R6.1.1.
See the Supported Configurations in Encrypted Mode section to determine the supported configurations on the client and trunk ports in each slice configured in encrypted mode
 Note | When the slice is configured in encrypted mode, the drop-lldp cannot be enabled. |
Note | When NCS 1002 is installed in a system where both the trunk interfaces in a slice are used, the two 250Gb 16QAM signals need to be co-routed on the same fiber (mandatory when the 5x100Gb client port is provisioned). Also, it is recommended to use adjacent wavelengths when the line modulation is set to 250Gb 16QAM. The reason for this is that the chromatic dispersion generates skew between wavelengths. Assuming a Dispersion of 10000 ps/nm, a span of 500 km, and using adjacent channel, the skew is evaluated in less than 200 ns and it is compensated by the deskew capability of NCS 1002. If the delta between the used channels is increased, the skew increases and it might exceed the skew compensation done by NCS 1002. |
To configure the slice with unencrypted traffic, use the following commands.
configure
hw-module location location slice [slice_number | all ] client bitrate { 10G | 40G | 100G } trunk bitrate { 100G | 200G | 250G } fec { softdecision7 | softdecision20 }
commit
To configure the slice with encrypted traffic, use the following commands.
configure
hw-module location location slice [slice_number | all ] client bitrate { 10G | 40G | 100G } trunk bitrate { 100G | 200G } fec { softdecision7 | softdecision20 } [ encrypted ]
commit
Examples
The following is a sample in which slice 0 is configured to send encrypted traffic with 100G client rate, 200G trunk rate, and FEC on the trunk ports is set to softdecision7.
configure
hw-module location 0/RP0/CPU0 slice 0 client bitrate 100G trunk bitrate 200G softdecision7 encrypted
commit
The following is a sample in which slice 0 is configured to send encrypted traffic with 10G client rate, 100G trunk rate, and FEC on the trunk ports is set to softdecision20. When a slice is configured with 10G client rate in encrypted mode, ten MACsec controllers are created for each slice. When all the four slices are configured with 10G client rate in encrypted mode, forty MACsec controllers are created for NCS 1002. Two MACsec controllers are created for the middle port, four controllers for the fourth port, and four controllers for the fifth port per slice.
configure
hw-module location 0/RP0/CPU0 slice 0 client bitrate 10G trunk bitrate 100G softdecision20 encrypted
commit
The following is a sample in which slice 0 is configured to send encrypted traffic with 40G client rate, 100G trunk rate, and FEC on the trunk ports is set to softdecision20.
configure
hw-module location 0/RP0/CPU0 slice 0 client bitrate 40G trunk bitrate 100G softdecision20 encrypted
commit
The following is a sample to configure all the slices with a specific client rate and trunk rate.
configure hw-module location 0/RP0/CPU0 slice all client bitrate 10G trunk bitrate 100G fec softDecision7 commit
configure hw-module location 0/RP0/CPU0 slice all client bitrate 40G trunk bitrate 100G fec softDecision7 commit
configure hw-module location 0/RP0/CPU0 slice all client bitrate 100G trunk bitrate 200G fec softDecision7 commit
The following is a sample to remove the configuration from all the slices.
configure no hw-module location 0/RP0/CPU0 slice all client bitrate 10G trunk bitrate 100G fec softDecision7 commit
configure no hw-module location 0/RP0/CPU0 slice all client bitrate 40G trunk bitrate 100G fec softDecision7 commit
configure no hw-module location 0/RP0/CPU0 slice all client bitrate 100G trunk bitrate 200G fec softDecision7 commit

Verify Slice Configuration
Use this procedure to verify whether the slice is correctly configured.

Displays the details of the slice such as the slice ID, client rate, trunk rate, and the traffic percentage carried on the trunk ports. The Encryption Supported field indicates whether the slice is provisioned with firmware that supports encryption or not.
The Provisioned status does not indicate that the traffic can flow immediately. For example, use the show controllers maCSecCtrlr 0/0/0/3 command output to view the provisioning information of the port after the slice is provisioned.
