FAQs

Q: What is the difference between the DCS-7280SR-48C6-M-R and the base DCS-7280SR-48C6-R?
A: The 'M' suffix denotes expanded memory with 32GB system DRAM (versus 8GB standard) and integrated SSD storage. This expanded configuration supports larger BGP routing tables, extensive ACL configurations, and advanced feature sets required for internet-scale routing and complex data center fabrics.

Q: Can the 100GbE QSFP28 ports be broken out to lower speeds?
A: Yes, each of the 6 x 100GbE QSFP28 ports can be broken out to 4x25GbE or 4x10GbE using appropriate breakout cables, effectively providing up to 24 additional 25G or 10G ports for increased connectivity flexibility.

Q: What does the rear-to-front airflow designation mean?
A: The 'R' suffix indicates rear-to-front (port-side exhaust) airflow, where cool air enters from the rear (non-port side) and exhausts through the front (port side). This airflow pattern is designed for hot-aisle/cold-aisle data center deployments where the switch is positioned with ports facing the hot aisle.

Q: Does this switch support full Layer 3 routing protocols?
A: Yes, the DCS-7280SR-48C6-M-R provides comprehensive Layer 3 switch router capabilities including BGP, OSPF, IS-IS, MPLS (LDP, RSVP-TE), SR-MPLS, EVPN, VXLAN, and 128-way ECMP. It can function as both a high-density Layer 2 switch and a full-featured Layer 3 router for spine-leaf architectures.

Q: Is this switch compatible with Arista CloudVision for centralized management?
A: Yes, the switch runs Arista EOS and fully integrates with CloudVision for centralized network configuration, compliance monitoring, topology visualization, and zero-touch provisioning across multi-site deployments. It also supports modern automation through Python scripting, REST APIs, and OpenConfig interfaces.
