C8500-12X4QC Description
C8500-12X4QC is a Cisco Catalyst 8500 Edge Platform model with 12 × 1/10GE SFP+ and mixed 40/100GE uplinks, purpose-built for SD-WAN aggregation and high-performance encrypted routing. It delivers up to 31.9 Gbps SD-WAN IPsec on IMIX (up to 96 Gbps with 1400-byte packets), and up to 197 Gbps IPv4 forwarding in autonomous mode, scaling to 8000 overlays (10000 per note). With 16 GB default DRAM (upgradeable to 64 GB), 16G/32G eUSB plus optional 480 GB M.2 SATA SSD, dual high-efficiency PSUs, and IOS XE programmability, C8500-12X4QC fits large branch hubs, metro edge POPs, and multi-cloud gateways requiring deterministic, secure throughput and automation at scale.

Key Features
up to 31.9 Gbps IPsec IMIX and 96 Gbps with 1400-byte packets, enabling encrypted aggregation for hub-and-spoke or full-mesh topologies.
12 × 1/10GE SFP+ plus 40/100GE QSFP28 and 40GE QSFP options; supports 4×10GE breakout on 40G ports for dense 10G handoffs (not supported in SD-WAN mode).
up to 197 Gbps IPv4 forwarding and up to 135 Gbps IPsec, suitable for non-SD-WAN encrypted WAN or data-center edge.
16 GB default DRAM (upgradeable to 64 GB) and eUSB/SSD options, supporting telemetry, logs, and monitoring agents.
dual power supplies and software redundancy (two IOS processes in routing mode) help maintain service during control-plane events.
hardware-anchored Secure Boot/SUDI with IOS XE APIs for automated policy, QoS, visibility, and segmented VPNs across cloud and WAN.
Application Scenarios
Sits at a carrier-neutral facility to terminate SD-WAN overlays from many branches, provide 40/100G peering to ISPs and IXPs, and enforce DIA/security policies before handing traffic to cloud and SaaS.
Acts as a high-throughput edge for backup, analytics, and database replication between private DCs and multiple clouds, using segmented VPNs/VRFs and QoS to prioritize bulk transfers without impacting user apps.
Aggregates encrypted WAN links from plants, warehouses, and OT islands; provides deterministic 10/40/100G handoffs to MES/SCADA services and telemetry platforms, supporting site isolation and rapid failover during maintenance windows.
