This action allows the user to sample traffic matched by tc classifier. The sampling consists of choosing packets randomly and sampling them using the psample module. The user can configure the psample group number, the sampling rate and the packet's truncation (to save kernel-user traffic). Example: To sample ingress traffic from interface eth1, one may use the commands: tc qdisc add dev eth1 handle ffff: ingress tc filter add dev eth1 parent ffff: \ matchall action sample rate 12 group 4 Where the first command adds an ingress qdisc and the second starts sampling randomly with an average of one sampled packet per 12 packets on dev eth1 to psample group 4.
