Command Function
DES-7200(config)# show ip arp inspection
interface
Show the DAI configuration of each layer
2 interface (including trust status and

For the products supporting NFPP, rate limit is done by NFPP, not DAI. Consequently,
this command shows only the trust status of an interface.
10.4 Precautions of
Configuring the Rate of
ARP Packets
Caution
In the single-device environment, when the CPU is busy, the rate of sending
ARP packets is limited to appropriately 150PPS~380PPS, even if the rate
oversizely exceeds the rate limitation. The deviation of the rate value may
occur in different environment.
In the stack environment, when the CPU of the backup device is busy, the
rate of sending ARP packets on the port is appropriately a dozon PPS with
the rate limit configured.
