Configuring Breakout

This chapter gives procedure to configure breakout.

Understanding Breakout

Breakout is the concept of splitting the higher density port like 100G or 40G to multiple independent and logical ports i.e. 100G->10x10G or 100G->2x40G or 40G->4x10G.This is possible due to multilane architecture of the optics and cables. The standard R/S/I/P format is 4-tuple. 5-tuple interfaces are represented as - R/S/I/P/SP, where SP indicates the breakout port.

The Cisco NCS 4000 series supports the breakout feature. This feature is supported on the following cards:

  • NCS4K-4H-OPW-QC2 card-Breakout enables a 40 Gigabit lane of the card to be split into four independent and logical 10 Gigabit Ethernet or OTU2/OTU2e ports. All the QSFP+ ports are break-out capable.

  • NCS4K-2H10T-OP-KS card-Using breakout, each 100 Gig lane of NCS4K-2H10T-OP-K can be used by further breaking to 10 G ports. There is no breakout pluggable. 100 G SFP is used for the breakout. Using breakout, each lane of NCS4K-2H10T-OP-KS card can be used separately and as a physical 10G port.

Configure Breakout Controller Using CTC

Purpose This task provisions the breakout controller for NCS4K-2H10T-OP-KS and NCS4K-4H-OPW-QC2, using CTC.
Tools/Equipment None
Prerequisite Procedures "Login to CTC" in System Setup and Software Installation Guide for Cisco NCS 4000 Series
Required/As Needed As needed
Onsite/Remote Onsite or remote
Security Level Provisioning or higher

Procedure

Step 1

In node view, double-click the line card.

Step 2

Click the Provisioning > Port Modules tabs.

Step 3

Click Lane Controllers.

Step 4

In the Lane Controllers dialog box, perform the following steps to configure the breakout controller:

  1. Select the port from the drop-down list.

  2. Set the PortMode, framing type, and mapping type for the port selected.

  3. Click Apply.

Stop. You have completed this procedure.
