OC Support for TXP and MXP Data Paths Using ZRP

This chapter describes open configuration details for 2x100GE-MXP-DD, 3x100GE-MXP-DD, 400GE-TXP-DD, and 4x100GE-MXP-DD datapaths using QDD ZRP pluggable.

Feature Description

OC Support for TXP and MXP Data Paths using ZRP

Cisco IOS XR Release 7.7.1

From this release onwards, in NCS1K4-OTN-XP line cards, you can configure the 2x100GE-MXP-DD, 3x100GE-MXP-DD, 4x100GE-MXP-DD, and 400GE-TXP-DD card modes using ZR+ pluggable via OpenConfig.

This enhancement improves efficiency, performance, and flexibility for customer networks allowing 2x100GE, 3x100GE, 400GE, and 4x100GE client transport over 400GE WDM wavelength.

Slices and Port Mapping

To configure the 400GE-TXP-DD and 4x100GE-MXP-DD lc modes, the following data path configurations are used.

LC Mode

Datapath

400GE-TXP-DD

 2x400GE-TXP-DD

4x100GE-MXP-DD

 You can take any combination of the following datapaths to configure the 4x100GE-MXP-DD lc mode, based on the requirement:

  • 2x100GE-MXP-DD

  • 3x100GE-MXP-DD

  • 4x100GE-MXP-DD

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