Worth Reading: Understanding Table Sizes on the Arista 7050QX-32

Arista published a blog post describing the details of forwarding table sizes on 7050QX-series switches. The description includes the base mode (fixed tables), unified forwarding tables and even the IPv6 LPM details, and dives deep into what happens when the switch runs out of forwarding table entries.

Too bad they’re describing an ancient Trident-2 ASIC (I last mentioned switches using it in 2017 Data Center Fabrics update). Did NDA expire on that one?
