FAQs

Q: What is the difference between the 48C8C and 48C8 models?
A: The DCS-7050SX3-48C8C variant features different system memory and flash storage configurations compared to the standard 48C8 model, while maintaining the same port count and switching performance.

Q: Can this switch support 25GbE connections?
A: No, the 48C8C model uses SFP+ ports that support 1G and 10G speeds only. For 25GbE support, consider the 7050SX3-48YC8 series which uses SFP28 ports capable of 1G/10G/25G speeds.

Q: What uplink flexibility do the QSFP100 ports provide?
A: The 8x QSFP100 ports support 100GbE, 40GbE, and breakout configurations including 4x10GbE and 4x25GbE using appropriate breakout cables and transceivers, providing flexible spine connectivity options.

Q: Is this switch suitable for leaf or spine roles?
A: The 7050SX3-48C8C-F is optimized for both top-of-rack leaf and fixed-configuration spine deployments, offering non-oversubscribed performance with high-density 10G server connectivity and 100G uplinks.

Q: What licensing is required for advanced features?
A: The 7050X3 series uses Arista's standard licensing structure. Advanced features like full routing tables, EVPN, VXLAN, and MPLS require optional FlexRoute or FLX-Lite licenses, while base features and automation tools are included.
