Want to summarize with AI?

Provides features, operating modes, supported data rates, and port mappings for OXP2-K9 cards in Cisco NCS 1014 systems.

The OXP2-K9 line card for the Cisco NCS 1014 system features 16 client ports and 16 trunk ports, supporting up to 12.8 Tbps of traffic. Supported client rates include 800GE, 400GE, and 100GE Ethernet. Each OXP2-K9 card contains 16 slices; each slice consists of one client port and one trunk port with a slice capacity of 800G, providing a total card capacity of 12.8 Tbps.

In Release 26.3.1, the OXP2-K9 card supports only 800G transponder mode.

Feature Name	Release Information	Feature Description
800G transponder configuration in NCS1K14-OXP2-K9 line card	Cisco IOS XR Release 26.3.1	The NCS1K14-OXP2-K9 is a 32 × 800G DWDM coherent optics line card designed for transponder and muxponder applications, supporting up to 12.8 T of traffic. It features 16 trunk and 16 client ports, allowing for up to 16 configurable slices with 1:1 mapping. In this release you can configure the muxponder slice mode with 800G trunk rate and 800GE client rates. This capability provides high-density connectivity, and enhanced spectral efficiency with simplified high-speed data transport for demanding network architectures.

Note

NCS1K4-OXP2-K9 supports daisy-chain connection of up to three slices only. Configurations with more than three slices are not supported due to high jitter accumulation on the far-end interface, which may result in Sync Loss alarms or FCS errors.

Configure the 800G transponder mode on the OXP2-K9 card

Enable high-bandwidth optical transmission by configuring the OXP2-K9 card to operate in 800G transponder mode, ensuring optimal performance and compatibility with network requirements.

Use this task to set up the OXP2-K9 card for 800G operation as part of a high-bandwidth optical network. Proper configuration ensures optimal transmission performance and compatibility.

Procedure

Set the OXP2-K9 card to 800G transponder mode using the hw-module location command.

Example:


RP/0/RP0/CPU0:ios#configure
Tue Apr 11 19:29:20.132 UTC
RP/0/RP0/CPU0:ios(config)#hw-module location 0/0/NXR0 
RP/0/RP0/CPU0:ios(config-hwmod)#mxponder-slice 0
RP/0/RP0/CPU0:ios(config-hwmod-mxp)#trunk-rate 800G
RP/0/RP0/CPU0:ios(config-hwmod-mxp)#client-port-rate 1 client-type 800GE

Configure the frequency on the trunk port. Refer to Change the trunk port frequency on a transponder card.
Configure the AppSel code on the trunk pluggable. Refer to Configure an AppSel code on an optical module.

Verify the 800G transponder mode configured on the QXP card.

Example:


RP/0/RP0/CPU0:ios#sh hw-module location 0/0/NXR0 mxponder-slice 0
Location:             0/0/NXR0
Slice ID:             0
