_arp_defend_rate/_ndp_defend_rate
Parameter
- Description
-
Number of unrequested address-defense ARP or NDP messages that can be generated in an hour period on any one physical network interface. The time period can be revised by configuring _arp_defend_period/_ndp_defend_period Parameter.
The
_arp_defend_rate
/_ndp_defend_rate
work together with the_arp_defend_period
/_ndp_defend_period
to prevent a system with a large number of configured IP addresses from flooding the network with ARP traffic.By default, the system will continuously broadcast an ARP announcement or NDP advertisement every five minutes for each address that already passed duplicate address detection. However, the total number of such ARP announcements or NDP advertisements from an interface is further limited to 100 messages per hour regardless of the number of configured addresses.
These parameters does not apply to normal ARP or NDP resolution nor to address defense due to detected conflicts. Rather, the parameters are implemented only on unbidden conflict detection traffic.
