Error when trying to corrupt packets in linux terminal (netem)

The following rule corrupts 5% of the packets by introducing a single bit error at a random offset in the packet: > sudo tc qdisc change dev ens8 root netem corrupt 5% But recently it gave me the following error: > Error: Qdisc not found. To create specify NLM_F_CREATE flag Could you kindly help me or provide me with some other methods to simulate packet corruption? I'm trying to simulate packet corruption to see how well my error detection mechanism works.
