ARP Inspection
– 346 –
Packets arriving on trusted interfaces bypass all ARP Inspection and ARP
Inspection Validation checks and will always be forwarded, while those arriving
on untrusted interfaces are subject to all configured ARP inspection tests.
◆ Packet Rate Limit – Sets the maximum number of ARP packets that can be
processed by CPU per second on trusted or untrusted ports.
(Range: 0-2048; Default: 15)
Setting the rate limit to “0” means that there is no restriction on the number of
ARP packets that can be processed by the CPU.
The switch will drop all ARP packets received on a port which exceeds the
configured ARP-packets-per-second rate limit.
