A filter handle is something like: "804::800" right? I've tried this (supose classes 1:1 and 1:2 exist): tc filter add dev eth1 parent 1: protocol ip prio 1 handle ::10 u32 match ip src 10.10.10.10 flowid 1:1 tc filter add dev eth1 parent 1: protocol ip prio 1 handle ::11 u32 match ip src 10.10.10.11 flowid 1:2 and then: tc filter del dev eth1 parent 1: protocol ip prio 1 handle ::11 but both filter are deleted... Am I missing something? tks a lot... Andre Patrick McHardy wrote: > Andre Correa wrote: > >> >> Hi list, I'm playing with tc and found a strange behavior when I try >> to delete filters.
