Arp Rate-Limit - H3C S3100 Series Command Manual

Command Manual (For Soliton) – ARP
H3C S3100 Series Ethernet Switches
By default, when the port state auto-recovery function is enabled, the recovery interval
is 300 seconds.
Note that:
You need to enable the port state auto-recovery feature before you can configure
the auto-recovery interval.
If you use the arp protective-down recover interval command to modify the
recovery time when the current port has been already shut down due to an
excessive ARP packet receiving rate, the previously configured interval applies to
the first port state recovery. Starting from the next state recovery, the new
recovery interval will take effect.
Examples
# Set the auto-recovery interval to 30 seconds.

By default, after a port is enabled with the ARP packet rate limit function, the maximum
ARP packet receiving rate on the port is 15 pps.

the maximum ARP packet receiving rate on the port by using the arp rate-limit
command.
