Fabric Overview
The Cisco NCS 6000 switch fabric is a three-stage cell based architecture with six fabric planes.
In a back-to-back system, the Universal Fabric Card (UFC) in the Cisco NCS 6008 Line Card Chassis (LCC)
implements all 3 stage. The Cisco NCS 6000 back-to-back system has six fabric planes that support data
traffic between the lines connected to the LCCs. The fabric planes are numbered 0 through 5.
In a multi-chassis system, Stage 1 and Stage 3 (S13) of the fabric are implemented in the Cisco NCS 6008
Line Card Chassis (LCC). Stage 2 (S2) of the fabric is implemented in the Cisco NCS 6000 Fabric Card
Chassis (FCC). Inter-stage connections between the LCC the FCC are implemented through a number of
bi-directional optical links.
The following figure shows a simplified view of the relationship between the line cards and the fabric. The
fabric planes are numbered 0 through 5.

For multi-chassis systems, each fabric plane is divided into three components or stages, which are numbered
S1, S2, and S3. Data arrives at the S1 stage in an LCC, passes over the fabric cables to the S2 stage in the
