[j-nsp] Experience with EX2500

[Wojciech Owczarek]

EX2500 is a re-branded Blade Networks (now IBM) switch. Juniper only
licensed some old code for their use so BladeOS is now miles away from
what it was when Juniper got it and it saw very little updates to
Juniper's version. The 2500 is usually stable but had some critical
bugs in the past, namely pressing "?" in the console causing traffic
gaps ;) It's reasonably stable now and the latency is in the upper
sub-micro region for medium frame sizes so maybe 900ns if you care -
it's a cut-through switch. The CLI is cisco-like but a little bit
simplistic and not too comfortable to work with - but works.

EX2500 also does no L3 whatsoever, it's a typical ToR access switch -
with the 4500, 4550 or QFX3500 you get the whole routing package and
JunOS.
