Arista DCS-7280TR-48C6-R | 7280R 48-Port 10G Switch, 6x 100G QSFP28

Q: What deployment scenarios is the DCS-7280TR-48C6-R best suited for?
A: The DCS-7280TR-48C6-R is ideal for leaf-spine data center architectures, storage networks requiring deep buffers, content delivery networks, and data center interconnects. It excels in environments with bursty traffic and high-density 10G server connectivity.

Q: Does this switch support VXLAN and EVPN for overlay networks?
A: Yes, the DCS-7280TR-48C6-R supports VXLAN overlay networks and EVPN control plane for network virtualization, multi-tenancy, and data center interconnect use cases when licensed appropriately with Arista FlexRoute capabilities.

Q: What routing protocols are supported on this platform?
A: The switch supports comprehensive Layer 3 routing including BGP, OSPF, IS-IS, MPLS, Segment Routing, and multi-path designs with up to 128-way ECMP. Full routing scale depends on the installed EOS license tier.

Q: Can the 100GbE QSFP28 ports be broken out into lower-speed connections?
A: Yes, each 100GbE QSFP28 port can operate at 40G or be broken out into 4 x 25G or 4 x 10G connections, providing flexibility for various uplink and connectivity requirements.

Q: What makes the deep buffer architecture important for this switch?
A: The 4 GB Virtual Output Queue architecture eliminates head-of-line blocking and handles bursty traffic, TCP incast, and mixed workloads without packet drops. This is critical for storage networks, distributed applications, and high-performance computing environments.
