30.4 Gratuitous ARP Troubleshooting
Gratuitous ARP is disabled by default. And when gratuitous ARP is enabled, the debugging
information about ARP packets can be retrieved through the command debug ARP send.
If gratuitous ARP is enabled in global configuration mode, it can be disabled only in global
configuration mode. If gratuitous ARP is configured in interface configuration mode, the
configuration can only be disabled in interface configuration mode. If gratuitous ARP is
enabled in both global and interface configuration mode, and the sending interval of gratuitous
ARP is configured in both configuration modes, the switch takes the value which is configured
in interface configuration mode.
