Frequently asked questions
What is the switching capacity and packet forwarding rate of the DCS-7050QX-32S-R?
The DCS-7050QX-32S-R delivers 2.56Tbps aggregate switching capacity with full-duplex, non-blocking architecture. Packet forwarding rate reaches 1440Mpps with 550ns latency. This enables wire-speed layer 2/3 performance across all 32x40GbE QSFP+ and 4x10GbE SFP+ ports simultaneously, making it ideal for high-density data center spine and aggregation deployments.
What port configurations are supported on the 7050QX-32S-R?
The switch supports flexible QSFP+ port configurations: 32x40GbE, 24x40GbE + 32x10GbE, or up to 96x10GbE via breakout cables. Four dedicated SFP+ ports support 1GbE/10GbE. This multi-speed flexibility allows operators to optimize port density and bandwidth allocation for diverse workload requirements without hardware changes.
Does the 7050QX-32S-R support VXLAN and SDN protocols?
Yes. The switch includes native VXLAN routing, bridging, and gateway functionality with VM Tracer for virtual machine tracking. It supports OpenFlow 1.0+, DirectFlow, and eAPI for programmable network control. These capabilities enable software-defined networking architectures, multi-tenant isolation, and automated network provisioning in modern cloud and virtualized data centers.
What redundancy and high-availability features are included?
The DCS-7050QX-32S-R includes 1+1 redundant hot-swappable 500W AC power supplies and N+1 redundant hot-swappable fans. Stateful Failover Recovery (SFR) self-healing software and Intelligent System Upgrade (ISU) enable non-disruptive software updates. Reversible airflow (rear-to-front in this model) supports flexible data center cooling strategies.
What monitoring and visibility features does the switch provide?
Advanced monitoring includes LANZ (Latency Analyzer and Microburst Detection) for congestion detection, DANZ advanced mirroring and tap aggregation, RFC 3176 sFlow, and multi-port mirroring. Integrated packet capture with TCPDump, optional 120GB SSD for logging, and streaming events (GPB encoded) provide comprehensive network-wide visibility for troubleshooting and performance analysis.
What is the routing table capacity and protocol support?
The switch supports 288K MAC address entries, 144K IPv4 routes, and 208K IPv4 host routes. Routing protocols include OSPF, BGP, EIGRP, RIP, VRRP, and policy-based routing. IPv6 support includes neighbor discovery, stateless autoconfiguration, and ICMPv6. Up to 64 ports per LAG and 1K groups for 64-way ECMP enable highly scalable multi-path forwarding.
What are the power consumption and environmental specifications?
Typical power draw is 150W; maximum is 302W. Dual 500W PSUs provide 92-93% efficiency (Platinum rated). Operating temperature range: 0-40°C. Storage temperature: -40 to 70°C. Relative humidity: 5-95%. Operating altitude: 0-10,000 feet. Compact 1RU form factor (19-inch rack mount) with tool-less rails simplifies installation in standard data center racks.
