Arista has an extra cost software option called FlexRoute that works like hamburger helper. It dilutes and extends the expensive TCAM [hamburger] to make it appear that there is more than it first appeared. With helper, 256K worth of TCAM is stretched to cover 1M routes, along with a promise that future recipes may cut that even further.
Data Sheet We think of this as a fixed configuration version of the 7504R chassis switch. Note that the 7280R data sheet does not support speeds lower than 10 Gb/s. It is possible that the switch family might have 1 Gb/s on some ports, the data sheet not withstanding. Arista ran a use case webinar on June 16, 2016. It says little about switch internals.
[June 2016] Kernelsoftware shows a list price for the 7280TR of $29,995. Compare with similar version from the previous generation 7280SE-68-R $39,995.
