TL;DR

The Cisco 8800 Series are distributed modular routers built on Silicon One that deliver up to 518 Tbps of system throughput. Available in 10 RU to 33 RU chassis sizes (4 to 18 slots), they support 800G, 400G, and 100G line cards with hot-swappable, redundant components throughout. Powered by IOS XR, they serve core, peering, DCI, and high-capacity aggregation roles for service providers and large enterprises.

Frequently Asked Questions

What chassis sizes are available?

The 8800 Series is available in 4-slot (8804, 10 RU), 8-slot (8808, 16 RU), 12-slot (8812, 21 RU), and 18-slot (8818, 33 RU) configurations.

What is the maximum system throughput?

With 800G line cards, the 8818 delivers up to 518.4 Tbps. With 400G line cards, it reaches 259.2 Tbps.

Can I mix different generation line cards?

Yes. IOS XR supports interoperability of Q100, Q200, and P100 line cards in the same chassis with configurable NPU compatibility modes.

What operating system does it run?

Cisco IOS XR with modular Linux-based packaging, segment routing, EVPN, and streaming telemetry. SONiC is also supported for data center use cases.

Are all components hot-swappable?

Yes. Route processors, line cards, fabric cards, fans, and power supplies are all hot-swappable with redundant supervisor, power, fabric, and cooling modules.
