Ask the Expert: Understanding hardware Architecture of NCS 6000

[Francine Richards]

The Cisco Network Convergence System 6000 (NCS 6000) helps enable superior network agility, packet optical convergence, and petabits-per-second system scale. The series facilitates the Evolved Programmable Network to support virtualization and programmability at the lowest total cost of ownership, while delivering high-bandwidth mobile, video, and cloud services to end users.

Hi Nikhil

We will be soon deploying NCS and have started working on it. Not sure If I am taking the correct word but could you let us know how NCS works on Green mode?

Thanks

[Nikhil Kapoor]

Hello,

Thanks for the question. I completely understand your query with use of NCS power consumption can be done. Going to LC architecture we have 5 slices each of 200 Gbps which computes to 1Tbytes per LC. . In an event we are not using any interface we can shutdown the slice, consequently saving the power. This is known as Green Mode for LC NCS.  Hope this answers your query.

Thanks, 

Nikhil

Thanks Nikhil and Osman.

I may want to ask one more question. Is 200 Gbps uni-directional or Bi-directional?

[Nikhil Kapoor]

Hello,

200Gbps per slice is bi-directional.

Thanks,

Nikhil

Hi

You may review some information on the green mode within the release notes, e.g. for 5.2.3:

http://www.cisco.com/c/en/us/td/docs/routers/ncs6000/software/release/notes/reln_523ncs.html

We can shut down a slice using a config CLI. The interfaces belonging to the slice that is shut down will not be visible. Entity MIB will show that the interfaces have been removed from the system.

CLI:

(config) # hw-module location <> slice <> shutdown

Hi Nikhil,

Does NCS supports multichassis? How about B2B

Thanks

Amit

[Nikhil Kapoor]

Hi Amit, 

Yes Multi Chassis is possible with NCS 6008 in a same fashion like we do for CRS via Control Ethernet connections. 

Thanks,

Nikhil

Hi Again,

A quick one For Multichassis and B2B could let us know the optics supported?

Thanks,

Amit

[Nikhil Kapoor]

Hi Amit,

Thanks for questions. Please feel free to ask as many questions. For Multi Chassis and B2B on NCS6008 can be achieved via CXP optical interconnects. 

Hope this helps.

Hi Nikhil,

I have been going through few docs and came across question. If you could help. Is there any way that we can breakout 100G LC in 10x10G and how could we check the port to slice mapping?

Thanks,

[Nikhil Kapoor]

Hello, 

Thanks for question. Please feel free to ask as many questions. Coming to your query yes there is way to break out 1x100G in 10X10G. 

Command to do so :

RP/0/RP0/CPU0:6008-A(config)#hw-module location 0/0/cpU0 slice 1 breakout 10G

For slice mapping we can execute below command.

RP/0/RP0/CPU0:6008-A#show uidb index location 0/0/CpU0 

Example output of command for slice mapping. 

<SNIP>

 Location        Interface-name   Interface-Type    NPU   UIDB-indices

--------------------------------------------------------------------------------

  0/0/CPU0       TenGigE0_0_0_0   Main Interface   0      1

  0/0/CPU0       TenGigE0_0_0_1   Main Interface   0      2

  0/0/CPU0       TenGigE0_0_0_2   Main Interface   0      3

  0/0/CPU0       TenGigE0_0_0_3   Main Interface   0      4

Hope this helps.
