1.2T line cards
This section describes the supported card modes, card configurations, and procedures to configure the card modes on the 1.2T line card.
A 1.2T line card
-
supports both module and slice configurations,
-
provides flexible trunk and client port assignment, and
-
enables high-capacity throughput for networking environments.
Port details
The line cards are equipped with trunk and client ports:
-
Two trunk ports (0 and 1), and
-
12 client ports (2 through 13).
Configuration modes
You can configure the line cards in these two modes:
-
Muxponder mode:
-
Both trunk ports are configured with the same trunk rate. The client-to-trunk mapping is sequential.
-
-
Muxponder slice mode:
The client-to-trunk mapping is fixed.
The table lists the client ports assigned to each trunk for the 1.2T card in muxponder slice mode

-
Configuration modes
You can configure the line cards in the following two modes:
-
Muxponder Mode:

Both trunk ports are configured with the same trunk rate.
-
The client-to-trunk mapping is in a sequence.
-
-
Muxponder Slice Mode: The client-to-trunk mapping is fixed.

Sub 50G Configuration
You can configure the sub 50G or coupled mode on the 1.2T line card only in the muxponder mode.
This table displays the port configuration for the supported data rates in the muxponder mode.

 Note |
In all x50G configurations, client traffic on the middle port is affected with ODUK-BDI and LF alarms after the power cycle or link flap on the trunk side. This issue is raised when the two network lanes work in coupled mode and move from low to high power. To solve this issue, create a new frame either at the near-end or far-end by performing shut or no shut of the trunk ports. |
Coupled Mode Restrictions
These restrictions apply to the coupled mode configuration:
-
Both trunk ports must be configured with the same bits-per-symbol or baud rate and must be sent over same fiber and direction.
-
The chromatic dispersion must be configured to the same value for both trunk ports.
-
When trunk internal loopback is configured, it must be done for both trunk ports. Configuring internal loopback on only one trunk results in traffic loss.
-
Fault on a trunk port of a coupled pair may cause errors on all clients including those running only on the unaffected trunk port.
Configure Split Client Port Mapping
You can configure the trunk port of the 1.2T line card to client port mapping for sub 50G data rates in the default mode or in the split client port mapping mode.
Follow thes steps to configure the split client port mapping:
Procedure
|
Step 1 |
Run the configure command to configure the card in muxponder module mode. Example:Activates the split client ports 2 and 3. |
|
Step 2 |
Run the hw-module locationlocationmxponder command to enter into the muxponder mode. Example: |
|
Step 3 |
Perform any of these steps to configure or remove the split client port mapping mode:
|
|
Step 4 |
Run the commit and end commands to commit the changes and exit the configuration mode. Example: |
|
Step 5 |
Verify the port mapping using the show hw-module locationlocationmxponder command. Example:This example shows how to verify the split client port-mapping configuration. |
The split client port mapping is configured.
Example
The following is a sample in which split-client-port-mapping is configured with a 450G trunk payload.
RP/0/RP0/CPU0:ios#configure
RP/0/RP0/CPU0:ios(config)#hw-module location 0/1/NXR0 mxponder

You can configure the 1.2T line card in the module (muxponder) or slice configuration (muxponder slice).
Configure the card in the muxponder mode
To configure the card in the muxponder mode, use these commands.
configure
hw-module location location mxponder client-rate {100GE | OTU4}
hw-module location location mxponder trunk-rate {50G | 100G150G | 200G | 250G | 300G | 350G | 400G | 450G | 500G | 550G | 600G }
commit
Configure the card in the muxponder slice mode
To configure the client data rates of the card in the muxponder slice mode, use these commands.
configure hw-module location location mxponder-slice mxponder-slice-number client-rate { 100GE|OTU4}
To configure the trunk data rates of the card in the muxponder slice mode, use these commands.
hw-module location location mxponder-slice trunk-rate { 100G | 200G | 300G | 400G | 500G | 600G }

In an optical transmission system, 3R regeneration helps extend the reach of the optical communication links by reamplifying, reshaping, and retiming the data pulses. Regeneration helps to correct any distortion of optical signals by converting it to an electrical signal, processing that electrical signal, and then retransmitting it again as an optical signal.
In Regeneration (Regen) mode, the OTN signal is received on a trunk port and the regenerated OTN signal is sent on the other trunk port of the 1.2T line card and the other way round. In this mode, only the trunk optics controller and coherentDSP controllers are created. Regeneration can be configured only on the 1.2T line card.
Configuring the Card in Regen Mode
You can configure the regeneration mode on the 1.2T line card. The supported trunk rates are 100G to 600G in multiples of 100G.
To configure the regeneration mode on the 1.2T card, use these commands:
configure
hw-module location location
regen
trunk-rate trunk-rate
commit
exit
Example
The following is a sample to configure the regeneration mode on the 1.2T line card with the trunk-rate 300.
RP/0/RP0/CPU0:ios#configure
RP/0/RP0/CPU0:ios(config)#hw-module location 0/0/NXR0
RP/0/RP0/CPU0:ios(config-hwmod)#regen
RP/0/RP0/CPU0:ios(config-regen)#trunk-rate 300
RP/0/RP0/CPU0:ios(config-regen)#commit
RP/0/RP0/CPU0:ios(config-regen)#exit
Verifying the Regen Mode
The following is a sample to verify the regen mode.

Configuring the BPS
The bits-per-symbol parameter allows you to configure the modulation format on optical interfaces. This setting directly impacts the spectral
efficiency and data rate on a per-wavelength basis.
Supported Line Cards
You can configure the Bits per Symbol (BPS) on the 1.2T and 2-QDD-C line cards to 3.4375 to support 300G trunk configurations on 75 GHz networks using these commands:
configure

Configure the Trunk Rate for BPSK
Trunk rates on the 1.2T and 2-QDD-C line cards can be configured to 50G, 100G, and 150G to support Binary Phase-Shift Keying (BPSK) modulation, optimizing the efficiency of carrying information over radio signals.
Configuration methods
You can configure trunk rates for BPSK modulation using these methods:
-
Command-Line Interface (CLI)
-
NetConf YANG
-
OC Models
