FAQs

Q: What chassis models are compatible with the DCS-7500R2AK-48YCQ-LC?
A: This line card is compatible with all Arista 7500R Series modular chassis, including the 7504R, 7508R, 7512R, and 7516R. It requires a compatible supervisor module and fabric modules for operation.

Q: What is AlgoMatch technology and how does it benefit my network?
A: AlgoMatch is Arista's advanced packet classification and traffic management engine that enables granular policy enforcement, quality of service, and traffic shaping. It supports up to 2 million routing entries, making it ideal for large-scale deployments requiring complex routing tables and precise traffic control.

Q: Can the 100GbE QSFP28 ports be used in breakout mode?
A: Yes, the 2x 100GbE QSFP28 uplink ports support breakout modes including 4x 25GbE or 2x 50GbE when used with appropriate optics such as SR4 or PSM4 transceivers or breakout DAC cables.

Q: What routing protocols and features does this line card support?
A: The DCS-7500R2AK-48YCQ-LC supports comprehensive Layer 2 and Layer 3 protocols including BGP, OSPF, IS-IS, MPLS, VXLAN, and EVPN. It delivers wirespeed performance with full routing tables of up to 2 million entries, making it suitable for core and spine layer deployments.

Q: Is this line card suitable for leaf-spine data center architectures?
A: Absolutely. With 48 high-density 25GbE downlinks for server connectivity and 2x 100GbE uplinks for spine connections, this line card is optimized for modern leaf-spine topologies, particularly in virtualized cloud environments and hyperscale data centers requiring low latency and high throughput.
