config gratuitous_arp send ipif_status_up
Purpose Used to enable/disable the sending of gratuitous ARP requests while the IP interface
status comes up.
Syntax
config gratuitous_arp send ipif_status_up [enable | disable]
Description The command is used to enable or disable the sending of gratuitous ARP request
packets while the IPIF interface comes up. This is used to automatically announce the
interface’s IP address to other nodes. By default, the state is disabled.
Parameters
enable − Enable sending of gratuitous ARP when IPIF status comes up.
disable − Disable sending of gratuitous ARP when IPIF status comes up.
Restrictions Only Administrator and Operator-level users can issue this command.
Example usage:
To enable send gratuitous ARP request in a normal situation:
DGS-3426:5#config gratuitous_arp send ipif_status_up enable
Command: config gratuitous_arp send ipif_status_up enable
Success.
DGS-3426:5#
config gratuitous_arp send dup_ip_detected
Purpose Used to enable/disable the sending of gratuitous ARP requests while a duplicate IP
address is being detected.
Syntax
config gratuitous_arp send duplicate_ip_detected [enable|disable]
Description The command is used to enable or disable the sending of gratuitous ARP request
packets while a duplicate IP is being detected. By default, the state is disabled. For this
command, the duplicate IP detected means that the system received an ARP request
packet that is sent by an IP address that matches the system’s own IP address. In this
case, the system knows that somebody is using an IP address that is in conflict with the
system. In order to reclaim the correct host of this IP address, the system can send out
the gratuitous ARP request packet for this duplicate IP address.
Parameters
enable − Enable sending of gratuitous ARP when a duplicate IP is detected.
disable − Disable sending of gratuitous ARP when a duplicate IP is detected.
Restrictions Only Administrator and Operator-level users can issue this command.
