Re: NCS-5504 with NCSNC57-36H6D-S and 4x10G Optics

mmelbourne · ‎03-03-2023

We have a NCS-5504 with NCSNC57-36H6D-S line card.

We wish to use a 40G optic in one of the ports to provide 4x10G breakout.

From the module notes:
https://www.cisco.com/c/en/us/products/collateral/routers/network-convergence-system-5500-series/datasheet-c78-742016.html

It states for the NCSNC57-36H6D-S that "Quad groups with ports 24-27, 28-31 and 32-35 do not have any restriction on combination of optics."

At the moment, the ports are all "Hun0/0/0/0-35" interfaces. Is there any documentation for the configuration of breakout for these line cards; I believe the "hw-module port-range <>" command may be required?

We only require port (port 35) configured as 4x10G.

Take a look at the breakout section here:

Thanks for the pointer. It's slightly confusing having a 57-series line card in a NCS5504 chassis. Which command is actually required? I am thinking it's the "hw-module port-range <>" as interfaces need to be renamed?

Is there any specific documentation for this linecard in terms of breakout?

Thanks for the pointers. I think the commands are very hardware-specific, even down to the specific ports.

Looking at: https://www.cisco.com/c/en/us/td/docs/iosxr/ncs5500/hardware-install/b-ncs5500-hardware-installation-guide/b-ncs5500-hardware-install-guide_chapter_01.html

It suggests the configuration of NC57-36H6D-S of ports 24-35 for 4x10G is achieved via "controller optics <>" commands.
