ARP filtering has been enabled. The Unfiltered and Filtered counts increment only when ARP filtering
has been enabled using the cable arp filter command. When cable ARP filtering is disabled, these
counters retain their current values until manually reset, using the clear counters command.
The following example shows how to display the devices that are generating or filtering more than 100
ARP requests per reporting period. Repeat the command to see how quickly the device is generating
ARP packets.

The following example shows how to display the devices that are generating or filtering more than 200
ARP replies per reporting period. Repeat the command to see how quickly the device is generating ARP

show cable arp-filter Field Descriptions (continued)
Description
Total number of ARP request packets that the cable interface was asked to
forward to the ARP proxy since power-on.
Number of ARP request packets that the cable interface sent to the ARP
proxy while filtering was enabled using the cable arp filter request-send
command.
Number of ARP request packets for the ARP proxy that the cable interface
dropped, because they would have otherwise exceeded the allowable
threshold value that was configured for the interface using the cable arp
filter request-send command.
All counters are 16-bit counters, with a maximum value of 65,535 packets. If the number of
packets exceeds this amount, the counter wraps back to zero and begins incrementing again.
