ICL cabling configurations
The following figures show acceptable cabling configurations for the inter-chassis link (ICL) feature between QSFP ports in core routing
blades. The recommended topology is the parallel type where at least four QSFP cables connect between both core routing blades on
any two directors. This provides ICL trunking between directors, ensuring redundancy. Parallel connections between core blades are
recommended.
Following are the maximum numbers of directors that you can connect using 4x32-Gbps quad SFP (QSFP) inter-chassis links (ICLs):
• Up to nine X6 (GEN6) directors can be connected in a full-mesh topology.
• Up to six directors are recommended in a full-mesh topology if connecting a mixture of X6 and GEN5 directors.
• Up to 12 directors can be connected in a core-to-edge topology.
