Hi all,
Recently I've tried to bind ip with mac, in order to control the use of ip.

The goal I want to achieve is:
1. One can only use the ip which is assigned to him
2. One can't use a non-assigned ip

I connected the switch via telnet and use the command: "configure iparp add <ip> <mac>" and "save." (For example, "configure iparp add 192.168.0.1 00:11:22:33:44:55")

However another computer(mac) can still use this ip(192.168.0.1) and goes on the internet without any problem. The switch's event log only shows "<date> <time> <CRIT:KERN> ARP:Static ARP conflict from <ip>/<mac> on <vlan>."

As a result, I can't make it right.

I was thinking maybe we can set an action(block) when conflict occurs, but after reading the manual, I fail in vain.

Can anyone help me with the problem? Thanks in advance.
