I am trying to capture packet coming from a switch (mirror data). but no packet is capturing. showing all packet is dropped by interface.
[root@localhost PacketReceiver]# tcpdump -i enp3s0f0 -vvv -w test.pcap tcpdump: listening on enp3s0f0, link-type EN10MB (Ethernet), capture size 262144 bytes ^C0 packets captured 0 packets received by filter 0 packets dropped by kernel 162856 packets dropped by interface
but from another interface which by which server is using internet, by tcpdump packets are capturing fine.
What is the problem. and what will be the solution.
