Figure 367 Configuring ARP Scanning
Table 156 Configuration items
Item Description
Interface Specify the interface on which ARP automatic scanning is to be performed.
Start IP Address
Enter the address range for ARP automatic scanning.
• To reduce the scanning time, you can specify the address range for scanning.
If the specified address range covers multiple network segments of the
interface's addresses, the sender IP address in the ARP request is the
interface's address on the smallest network segment.
• If no IP address range is specified, the device only scans the network where
the primary IP address of the interface resides for neighbors, and sends ARP
requests in which the sender IP address is the primary IP address of the
interface.
IMPORTANT:
• You must specify both the start IP address and the end IP address. Otherwise,
specify neither of them.
• Start and end IP addresses must be on the same network segment as the
primary IP address or a specific manually configured secondary IP address of
the interface. The end IP address must be higher than or equal to the start IP
address.
End IP Address
Also scan IP addresses of
dynamic ARP entries
Select to scan IP addresses already existent in ARP entries.
After the preceding configuration is complete, click Scan to start an ARP automatic scan.
To stop an ongoing scan, click Interrupt.
After the scanning is complete, a prompt Scanning is complete appears. You can view the generated
dynamic ARP entries by selecting Advanced > ARP Anti-Attack > Fixed ARP from the navigation tree.
Configuring fixed ARP
The static ARP entries changed from dynamic ARP entries have the same attributes as the static ARP
entries manually configured.
