Does anyone have idea why the ip and mac address cannot store in dhcp snooping binding table? if ip address cannot store in ip dhcp snooping binding table. my pc cannot ping to gateway. The router i have configure as dhcp server so i have disable 82 options in ip dhcp snooping. attach router and switch configuration
By default it would store one ip address and one mac for interface. Thats how you configure it. However if port Fa0/13 had a previous ip addres and mac and you plug another device it would cause the message you received. To fix that you need the ip arp inspection trust command on the interface the message appears. This is how I fix it when this message happend to me.
if i apply ip arp inspection trust command in the interface. it will auto bypass the interface. the objective i want to do is untrust interface get inspect before traffic send out. do you see any config or else is incorrect?
