An ACL would do the trick. Or are you asking about a static ARP entry?<BR /> Thu, 24 Aug 2017 18:31:00 GMT https://community.extremenetworks.com/t5/extremeswitching-exos-switch/how-to-lock-a-static-ip-in-interface-port-in-the-switch-exos-15/m-p/40653#M9224 StephenW 2017-08-24T18:31:00Z https://community.extremenetworks.com/t5/extremeswitching-exos-switch/how-to-lock-a-static-ip-in-interface-port-in-the-switch-exos-15/m-p/40654#M9225 I would like of a single static ip on the interface the switch.<BR /> The interface is configured in vlan XXX and the IP the host is configured local in the computer.<BR /> <BR /> Thu, 24 Aug 2017 18:55:00 GMT https://community.extremenetworks.com/t5/extremeswitching-exos-switch/how-to-lock-a-static-ip-in-interface-port-in-the-switch-exos-15/m-p/40654#M9225 Fagner 2017-08-24T18:55:00Z https://community.extremenetworks.com/t5/extremeswitching-exos-switch/how-to-lock-a-static-ip-in-interface-port-in-the-switch-exos-15/m-p/40655#M9226 Hi Fagner,<BR /> <BR /> Are you asking if you can assign an IP address to a particular switch port? <BR /> Something like a routed port?

To this, I want lock the address IP in the interface the switch.
