We have about a dozen 2148Ts connected to 4 Nexus 5Ks and a couple of 7Ks

I would absolutely NOT pick the 2148Ts for just switching unless you had
some larger data center needs; they and their "parent" 5Ks don't route ..
.so we do some ( and we wanted to) vlan tagging on servers to bypass
routing.

I will say that "show log last 20" is worth every penny :)

They are stable if you hook them up right - currently you can not do
active/active with a FEX connected to multiple 5Ks & do LACP teaming to
servers.

Got question  - shoot them on over ...
