You can configure the slice with traffic on client and trunk ports. All five client ports of the slice need to be configured at the same bitrate except for mixed mode configuration. 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.

Examples
The following is a sample in which slice 0 is configured in mixed mode, and FEC on the trunk ports is set to softdecision7.
configure
hw-module location 0/RP0/CPU0 slice 0 client bitrate 10G-100G trunk bitrate 200G fec SoftDecision7
commit
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.

Note
|
Until R6.3.2, if the user wants to modify the slice configuration using the hw-module command, the existing slice must be deleted and new slice must be configured. From R6.5.1, the user can directly change the
existing parameters on the configured slice without deleting the slice.
|
The slice configuration can be done using hw-module configuration or terminal-device configuration. However, the hw-module
configuration cannot be modified or deleted using the terminal-device configuration and vice versa.
