I have a SGE2010P and I would like to konw how to agreggate an ip address to a port.  Ex...force the IP address 192.168.0.1 use the port g01 only, if another computer using the same IP try use another port the switch must block that.  The intention is protect the my windows DHCP.

Dear Anderson,

Thank you for participating in the Support Community. My name is NIco Muselle from Cisco Sofia SBSC.

If the only thing you want to do is to prevent a rogue DHCP server to connect to the network and distribute IP addresses, the SGE2010P has a function called DHCP snooping. In this function, if enabled, you can select the port that your DHCP server is connected to and set it as a trusted port. This way, only a the server connected to this port will be allowed to offer IP addresses.

If however you want to bind a specific IP address to a specific port, you can create IP an IP access-list for every port to allow only one IP address to send traffic on that port (you could do the same based on MAC address as well using either MAC-based access-lists or implementing port security)

The option you want to implement demands highly on your requirements, but I hope I guided you a little on what are the options you could use for your scenario.

Best regards,
