Hi,

You may try:

testpmd> port stop all

or:

testpmd> port stop <port_id>

to stop a port, while ‘stop’ and ‘start’ here is actually stop or start fwd engine.

I have faced the following issues in new dpdk 22.11 released version:

testpmd> port config 0 speed 100 duplex half
Please stop port 0 first
dpdk 22.11 error: please stop port 0 first dpdk even though it's already stopped!

same for :
testpmd> port config 0 tx_offload vlan_insert on
Error: Can't config offload when Port 0 is not stopped
testpmd> stop
Packet forwarding not started
testpmd> port config 0 tx_offload vlan_insert on
Error: Can't config offload when Port 0 is not stopped
