Item Description
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.
The number of static ARP entries changed from dynamic ARP entries is restricted by the number of
static ARP entries that the device supports. As a result, the device might fail to change all dynamic
ARP entries into static.
Suppose that the number of dynamic ARP entries is D and that of the existing static ARP entries is S.
When the dynamic ARP entries are changed into static, new dynamic ARP entries might be created
(suppose the number is M) and some of the dynamic ARP entries might be aged out (suppose the
number is N). After the process is complete, the number of static ARP entries is D + S + M – N.
From the navigation tree, select Advanced > ARP Anti-Attack > Fix.
The fixed ARP configuration page appears, as shown in Figure 357. The page displ
ays all dynamic
ARP entries and static ARP entries (including manually configured and changed by the fixed ARP
feature).
