Ok,
I have found the problem,
In the file of configurations proposed by IE (for dynamips) it
foresees for every SW (with two NM-16ESW) a memory of 128, which is
not enough to work two NM-16ESW.
It uses 256 ram.
Example:
[[Router SW1]]
model = 3640
ram = 256
slot1 = NM-16ESW
slot2 = NM-16ESW
Ernesto.
