I have a package decoder receiving traffic from a Gigamon TAP but since few days cant get any, there are any way to check if the Decoder is getting the traffic using CLI?
You could run tcpdump -i <interface> from the CLI of the Network Decoder to see if you're receiving any traffic from the Gigamon tap. Make sure that the interface that you select is the capture interface (tcpdump -D will show you an output of all available interfaces).
Let us know what you find!
