What port configuration and speeds does the DCS-7260QX-64-R support?

The DCS-7260QX-64-R features 64x40GbE QSFP+ ports flexible for 10GbE/40GbE breakout via quad mode and 2x10GbE SFP+ ports. This high-density setup delivers 5.12Tbps switching capacity and 3.8Bpps forwarding, ideal for non-blocking data center fabrics with jumbo frames up to 9216 bytes.

What is the switching performance and latency of this switch?

It provides 5.12Tbps full-duplex throughput and up to 3.8 billion packets per second with low average latency under 450ns for 40GbE ports. The non-blocking architecture supports wire-speed across all ports, enhanced by 64MB dynamic buffers for bursty traffic in spine/leaf roles.

What management and monitoring features are included?

EOS platform offers CloudVision, SNMPv1-3, sFlow, AEM event management, TCPDump packet capture, CLI scheduler, and Linux tools. Additional features include Blue Beacon LED, USB restore, and VM-based extensibility with Python/C++ support for custom automation.

What redundancy and reliability options does it have?

1+1 hot-swappable AC power supplies, N+1 redundant fans, front/rear airflow options, Stateful Fault Repair (SFR), Smart System Upgrade (SSU), and live patching ensure high availability. Resilient x86 CPU with 4GB DRAM supports control plane protection.

Is it suitable for spine deployments in large data centers?

Yes, with 128K IPv4 routes, 136K MACs, BGP/OSPF/IS-IS, 128-way ECMP, VXLAN, and high port density, it excels as a spine switch for scale-out fabrics handling massive route tables and low-latency aggregation.

What Layer 3 routing protocols are supported?

Full support for OSPF/OSPFv3, BGP/MP-BGP, IS-IS, RIPv2, PIM-SM/SSM/BiDir, VRF, BFD, and Anycast RP. This enables robust IP fabrics with resilient ECMP and multicast for cloud and enterprise data centers.
