How to Determine the failed port with DHCP Snooping
If I understand DHCP snooping is used to prevent usage of Rogue DHCP servers in the Network.
Let 's say someone has plugged a Rogue DHCP server in the Network and DHCP snooping has detected it. in This case how do you tell which port on the switch that the Rogue DHCP server is connected to.
If I am not wrong, Network Admins document each user Network Drop and map it to the Switch name, location and port number.
I am not sure if show DHCP snooping will show the port number that has failed, it will show just the Mac address of the device that has attempted the DHCP client request.
Thank you
