Cisco 8000 Advance Core & Agg 400G Upgrade

Increase backbone capacity without replacing the platform around it. The Cisco 8000 Advance Core & Agg 400G Upgrade is built for teams that need to raise throughput in core and aggregation layers while preserving the operational model of the Cisco 8000 family. This upgrade is a strong fit for network teams planning for higher traffic volumes, denser east-west flows, and more demanding aggregation requirements. It supports a deliberate expansion strategy where the goal is to add 400G capability and keep the existing architecture intact. For procurement and infrastructure leaders, the value is in targeted investment. Rather than funding a broader refresh, this upgrade helps extend the life and capacity of Cisco 8000 deployments with a focused entitlement aligned to core and aggregation growth.
