Hello all: It looks like tc thinks I set a token bucket filter on my interface: # tc -s qdisc ls dev v1252 qdisc tbf 8006: root refcnt 2 rate 1000Kbit burst 2Kb lat 5.0ms Sent 6788208 bytes 51190 pkt (dropped 0, overlimits 0 requeues 0) rate 0bit 0pps backlog 0b 0p requeues 0 But I am still seeing bandwidth consumption hitting 80mbit/sec. Any ideas why it would not be working? This is a CentOS server with all the latest updates installed. V1252 is a KVM guest running on the machine.

Take a look at the attached graph. Any ideas why tc is not limiting the bandwidth?
