SNAT and GARP-s for all IPs in the SNAT pool?

Is this by design that G-arps are sent every 30 sec from ALL IP:s in an SNAT pool from the vrrp-a master? even if the IPs are not even used?!

    Hi Criiser,

    The 30 second Gratuitous ARPs (request/reply) that you see from the wireshark trace is by design within the AX Series. The purpose of GARPs is for the downstream switches to be aware that connections are good. In addition, the GARPs assist in the updates of the ARP table.
