ip arp inspection limit
This command sets a rate limit for the ARP packets received on a port. Use the no form to restore
the default setting.
Syntax
ip arp inspection limit {rate pps | none}
no ip arp inspection limit
pps - The maximum number of ARP packets that can be processed by the CPU per second.
(Range: 0-2048, where 0 means that no ARP packets can be forwarded)
none - There is no limit on the number of ARP packets that can be processed by the CPU.

Command Usage
• This command only applies to trusted or untrusted ports.
• When the rate of incoming ARP packets exceeds the configured limit, the switch drops all ARP
packets in excess of the limit.
Example
Console(config)#interface ethernet 1/1
Console(config-if)#ip arp inspection limit rate 150
Console(config-if)#
ip arp inspection trust
This command sets a port as trusted, and thus exempted from ARP Inspection. Use the no form to
restore the default setting.
