26.19.2.3 Syslog
The Switch can send syslog messages to the specified syslog server (Chapter 47 on page 395) when it
forwards or discards ARP packets. The Switch can consolidate log messages and send log messages in
batches to make this mechanism more efficient.
26.19.2.4 Configuring ARP Inspection
Follow these steps to configure ARP inspection on the Switch.
1 Configure DHCP snooping. See Section 26.19.1.4 on page 253.
Note: It is recommended you enable DHCP snooping at least one day before you enable
ARP inspection so that the Switch has enough time to build the binding table.
2 Enable ARP inspection on each VLAN.
3 Configure trusted and untrusted ports, and specify the maximum number of ARP packets that each port
can receive per second.
