[c-nsp] TLU/PLU memory on engine 2 line card (12000)

[Marc Binderberger]

Hi Drew,

PLU (pointer lookup) and TLU (table lookup) is memory used by the  
layer3 ASIC. It contains your FIB/MFIB/LFIB data (read: your CEF and  
labels).

The packet memory keeps - the packet :-)

by non-user-upgradable, correct, you cannot upgrade it. Not sure what  
happens if you try it but likely the card refuses to work.


Regards, Marc
