    So you only want a single IP to source traffic on that port? An ACL would do the trick. Or are you asking about a static ARP entry?

    I would like of a single static ip on the interface the switch.
    The interface is configured in vlan XXX and the IP the host is configured local in the computer.

    Hi Fagner,

    Are you asking if you can assign an IP address to a particular switch port?
    Something like a routed port?

    Hi Fagner,

    all depends what's your current network configuration and what equipment you have.

    Lets assume hosts are getting IP from DHCP server,
    then you can use for example ip security features like:
    Dhcp Snooping + Source IP Lockdown + ARP Validation, etc..

    If you have statuc IP, you can do this with ACL , and so on...

    The best solution is to use DHCP so you can use the dhcp snooping with IP source lock-down option Jarek recommended. That would prevent static IP's from being used.
