Chapter 1 IP Address Configuration Commands
If there are a large number of unresolved entries in the
ARP cache table and they do not disappear after a period
of time, this command can be used to limit the quantity of
the unresolved entries.
The following configuration sets the maximum number of
the unresolved items as 500.
arp unresolve 500
Privileged mode.
This command can be used to refresh an ARP cache
table.
On a NFPP-based(Network Foundation Protection Policy) device,
it receives one ARP packet for every mac/ip address per second
by default. If the interval of two clear arp times is within 1s, the
second response packet will be filtered and the ARP packet will
not be resolved for a short time.
The following is an example of removing all dynamic ARP
mapping records.
