Hi ,
We have a serious issue in our environment with arp inspection feature , we are enabling this feature on all our sites switches and we are even increasing the limit rate to 100 but still the ports are going to error disable state !! Sometimes we are put the command (ip arp inspection trust) but still some ports are going to err-disable state . We are getting some logs like :
%SW_DAI-4-PACKET_RATE_EXCEEDED: 128 packets received in 139 milliseconds on Fa2/9.
%PM-4-ERR_DISABLE: arp-inspection error detected on Fa2/9, putting Fa2/9 in err-disable state
So what is the causes of increasing this limit rate to 200 or 300 for example
Note : The issue is happening on different switches models and different IOS versions .
