excellent tcpdump command to find network details for interface and their VLAN details

tcpdump -nn -v -i eth2 -s 1500 -c 1 ‘ether[20:2]==0x2000’ 2>/dev/null|egrep “port-ID|Address|Devices-ID|VLAN”

This command will be very useful when you trouble shoot network interface, especially when you requested new network patching for a particular vlan network
