FAQs

Q: What is the difference between the 7280TR and 7280SR models?
A: The 7280TR features 48x 10GBASE-T RJ45 copper ports, while the 7280SR has 48x 10GbE SFP+ fiber ports. Both models share the same 6x 100GbE QSFP28 uplinks and switching architecture, with the TR optimized for copper-based server connectivity.

Q: Can the 100GbE QSFP28 ports be used for 40GbE or lower speeds?
A: Yes, each QSFP28 port supports 100GbE, 40GbE, and can break out to 4x25GbE or 4x10GbE, providing deployment flexibility for mixed-speed environments and incremental migration paths.

Q: What layer 3 routing capabilities does the DCS-7280TR-48C6-F support?
A: The switch supports full Layer 3 routing with protocols including BGP, OSPF, ISIS, VXLAN, and MPLS. The FlexRoute engine enables internet-scale routing with support for over 256K routes, making it suitable for leaf, spine, and data center interconnect roles.

Q: Is this switch suitable for leaf-spine data center architectures?
A: Yes, the DCS-7280TR-48C6-F is designed specifically for leaf roles in modern data center fabrics, with 48 copper ports for server connectivity and 6x 100G uplinks for high-bandwidth spine connections. It supports MLAG, ECMP, and VXLAN overlay networks.

Q: What operating system does this switch run and does it require licensing?
A: The switch runs Arista EOS (Extensible Operating System), a single modular Linux-based OS used across all Arista platforms. Base features are included; advanced capabilities such as FlexRoute with extended routing tables, VXLAN, and automation may require additional software licenses.
