30 Assembling a Switch Stack
Figure 1-9. Switch Stack Using 40GbE Ports on Two Aggregators
Use only QSFP transceivers and QSFP cables (s eparately purchased) to
connect stacking ports; for example:
1
Insert a QSFP cable in the bottom base-module port on the rightmost
Aggregator.
2 Connect the cable to the bottom base-module port on the next Aggregator
to the left.
3 On the leftmost Aggregator, connect the top base-module port to the top
base-module port on the rightmost Aggregator to create a loop.
NOTE: The resulting topology allows the stack to function as a single switch with
resilient fail-over capabilities.
