scale is important, but it depends on your server environment. mostly legacy kit -- dual-home the n2k. servers with teamed nic -- single home the n2k and team on the server.
it is possible as of 5.1(3)n2(1) or so to run 'enhanced vpc' (basically vpc on either side of the n2k) -- but i feel its overkill, unless you need a transitory state for single- to multi-homed compute. you pay for it on scale, though. q. -= sent via iphone. please excuse spelling, grammar, and brevity =- On May 25, 2013, at 9:07, manderson <[email protected]> wrote: > I thought this was a limitation on the 7k, but it makes sense that it would > apply to the 5k as well.
