Parameters
None
Description
Use the arp rate-limit enable command to enable the ARP packet rate limit function on the port, that is,
to limit the rate of ARP packets passing through the port. If a rate (the maximum ARP packet rate is 15
pps by default) is specified, exceeding ARP packets will be discarded.
Use the undo arp rate-limit enable command to disable the ARP packet rate limit function on the port.
By default, the ARP packet rate limit function is disabled, that is, ARP packet rate is not limited on a port.
Note that among S3100 series switches, only S3100-EI series switches support the two commands.
