Arista DCS-7280SR2K-48C6-M-F | 7280R2 48-Port 10/25G Switch Router, 6x 100G QSFP

Q: What port configurations are supported on the DCS-7280SR2K-48C6-M-F?
A: The switch supports flexible port configurations with 24x 10GbE and 24x 25GbE SFP28 ports (configurable in groups of 4), plus 6x 100GbE QSFP ports. The QSFP ports can operate as 100GbE, 40GbE, or breakout to 4x 25GbE or 4x 10GbE, providing exceptional deployment flexibility for evolving network requirements.

Q: What is AlgoMatch and how does it benefit this switch?
A: AlgoMatch is Arista's advanced packet matching technology available on the 7280R2K series, combining general-purpose memory with optimized software algorithms to deliver higher-scale access control lists, policy-based forwarding, and flow visibility. It enables over 24,000 ACL entries with minimal performance impact, ideal for security policies and advanced traffic engineering.

Q: What routing capabilities does the 7280SR2K-48C6-M-F offer?
A: The switch router supports full Layer 3 routing with over 2 million IPv4 routes using FlexRoute technology, 768K host routes, and advanced protocols including BGP, OSPF, ISIS, PIM, EVPN, VXLAN, Segment Routing, and MPLS (requires appropriate EOS licenses). It's designed for large-scale leaf-spine fabrics and internet peering applications.

Q: Is the expanded memory configuration beneficial for all deployments?
A: The expanded memory (M designation) is particularly valuable for environments requiring deep routing tables, extensive ACLs, advanced telemetry, or multiple VRF instances. Standard data center leaf deployments may not require it, but internet edge routers, large enterprise aggregation layers, and service provider networks benefit significantly from the additional DRAM and built-in SSD.

Q: What Arista EOS features are available on this platform?
A: The switch runs the full Arista EOS with support for Zero Touch Provisioning, VM Tracer, LANZ (microburst detection), DANZ (advanced mirroring and TAP aggregation), Advanced Event Management, sFlow, MLAG, 128-way ECMP, and stateful failover. EOS provides Linux-based programmability with REST APIs, Python scripting, and third-party application integration.
