Configure 400G TXP and MXP Data Paths

This chapter describes the required configurations for configuring the 400G TXP and MXP datapaths using CFP2 DCO.

From Release 7.5.1 onwards the OTN-XP card supports Openconfig configuration for Muxponder Mode 4x100G MXP and 400G TXP on ports 12 and 13 for CFP2 DCO.

Feature Description

OC Support for 400G TXP/MXP

Cisco IOS XR Release 7.5.1

This feature allows you to configure the 400G TXP and 400G MXP using CFP2 DCO.

On the OTN-XP card, you can configure OC datapath on a single 400GE or 4x100G payload that is received over the client port as a 400G signal over DWDM on the line side.

The card improves efficiency, performance, and flexibility for customer networks allowing 400GE or 4x100G client transport over 400G WDM wavelength.

Slices and Port Mapping on 400G TXP/MXP

The 400G MXP and 400G TXP can be configured with the same LC mode. Following are the supported operating modes to configure 400G TXP and 400G MXP datapaths:

  • 2x400G-TXP

  • 2x4x100G-MXP

  • Mix of MXP/TXP

The following tables shows port maping for slices 0 and 1.
