It seems that cat4500 with sup9 running 3.11.5E doesn't report QoS byte stats on its CBQOS MIB.
I can clearly see bytes stats using 'show policy-map int' command and I can get packet per second stats using CBQOS MIB but bytes counters are all zeros.
My question is whether this is expected and is there perhaps a magic hidden command to enable these missing stats?
