When I connected the wireshark to the normal L2 access port in vlan 2 and capture the packets. I am noticing lots of tcp traffic between different ports in my wireshark . I checked the core switch cisco 4507R but could not seen any span configured . Most of the ports are trunk ports and other unused ports are shutdown.My wireshark connected port is access port in vlan 2.
Could anyone guide me the work around.
