Niestety downgrade nie rozwiązał problemu, więc postanowiliśmy postawić CSR 1000v tylko do routowania Publicznych adresów.

I niestety poprawy nie ma, natomiast na tym routerze widać trochę więcej, a mianowicie:
Input queue: 0/1000/9156026/0 (size/max/drops/flushes); Total output drops: 0 na interfejscie lacza internetowego ma niesamowitą ilość dropów na kolejce input.
Wygląda to jak by SPD zadzialalo jak przy zapchanej sieci, ale to jest raczej nie mozliwe przy takich prędkościach
