4.7.8.3 Interface Configuration
The Security > DAI > Interface Configuration page is used to specify the ports that require ARP inspection, and to adjust the
packet inspection rate.
Port – Port or trunk identifier.
Mode – Configures the port as trusted or untrusted. (Default: Untrusted)
By default, all untrusted ports are subject to ARP packet rate limiting, and all trusted ports are exempt from ARP packet
rate limiting. 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 for Un-trust Mode (0-2048 pps) – 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.
