Frequently asked questions
What is the switching capacity and port configuration of the DCS-7280QRA-C36S-F?
The DCS-7280QRA-C36S-F delivers 2.88Tbps of wire-speed switching capacity with 4GB packet buffer. It provides 36x40GbE QSFP+ ports or flexible configuration with 18x40GbE and 12x100GbE QSFP ports. All ports support non-blocking, full-duplex forwarding, enabling simultaneous line-rate traffic across all interfaces for demanding data center workloads.
What routing and Layer 3 capabilities does the 7280RA support?
The 7280RA supports comprehensive Layer 3 routing including OSPF, OSPFv3, BGP, MP-BGP, IS-IS, and RIPv2. It scales to 768K IPv4 and IPv6 host routes with 24K ACL entries per forwarding engine (192K total system capacity). VXLAN gateway functionality enables multi-tenant cloud deployments with VRF and MLAG support for redundancy.
How does AlgoMatch differentiate this switch for algorithmic trading and HPC?
AlgoMatch is an integrated engine enabling advanced algorithmic matching and traffic engineering capabilities. Combined with IEEE 1588 PTP timing support, it delivers deterministic packet forwarding and ultra-low latency required for financial trading systems and HPC cluster interconnects. The 4GB buffer and distributed scheduler minimize packet loss during traffic bursts.
What virtualization and cloud networking features are included?
The 7280RA includes VXLAN bridging and routing with VRF and MLAG support for multi-tenant cloud environments. VM Tracer provides VMware integration for visibility into virtual machine traffic. 768K MAC address capacity and advanced QoS features (802.1Qbb PFC, 802.1Qaz ETS) ensure efficient east-west traffic optimization in cloud data centers.
What management and monitoring capabilities does the system provide?
Management features include CloudVision integration, configuration rollback and commit, 100/1000Mbps management port, and RS-232 serial console. Monitoring includes RFC 3176 sFlow, IEEE 1588 PTP, optional SSD for logging and packet capture, and advanced event monitoring. DANZ mirroring and TAP aggregation provide enhanced network visibility.
