ICL Cabling Configurations
The following figures show acceptable cabling configurations for the 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. Although the
following illustrations show X6 Directors, the discussion applies to X7 Directors as well.
Following are the maximum numbers of directors that you can connect using 4x Gen 7 QSFP ICLs:
•
Up to nine X7 (Gen 7) directors can be connected in a full-mesh topology.
•
Up to six directors in a full-mesh topology if connecting a mixture of directors.
•
Up to 12 directors can be connected in a core-to-edge topology.
To connect multiple X7 Directors via ICLs, a minimum of four ICL ports (two on each core routing blade) must be
connected between each chassis. The dual connections on each core blade must reside within the same trunk group. If
more than four ICL connections are required between a pair of directors, additional ICL connections should be added in
pairs (one on each core blade). ISLs and ICLs can co-exist between the same pair of directors if the ISLs and ICLs are on
different logical switches.
The following illustration shows the minimum connectivity between a pair of X7-8 chassis:
