Campus aggregation and modular core planning

Build the core configuration around the chassis, supervisor, line cards and required redundancy.

Deployment scope

Build the core configuration around the chassis, supervisor, line cards and required redundancy. Start with service traffic, uplink demand and failure boundaries. Select a supported chassis and supervisor combination, then allocate line-card slots and power. Check usable slot bandwidth as well as the sum of front-panel port rates.

Component decisions

C9500-16X and C9500-32QC have different port layouts. Compare the actual interfaces rather than treating all C9500 switches as interchangeable.
C9400-LC-48XS provides 1/10G fiber ports and requires the documented C9400X-SUP-2 or SUP-2XL combination. C9400-LC-24S and -48S are 1G cards.
Chassis, supervisors, power supplies, fans, optics and software entitlements must be listed separately unless the offered bundle explicitly includes them.

Acceptance plan

Reconcile the offered bill of materials with the installed hardware.
Verify boot, module recognition, fabric capacity and supported software.
Exercise the planned link and supervisor failover behavior.

Configuration boundary

The line-card port count describes one component. It does not prove that a chassis has the required supervisor, fabric capacity, cooling or power. A photograph of a fully populated chassis is a reference illustration, not a packing list.
