        Do not configure many VLANIF interfaces on the S2352/S3300 due to limitations on specifications and hardware performance. This prevents attacks to the CPU from numerous ARP packets or ARP Miss messages and overhigh CPU usage.

        Run the arp-fake expire-time 30 command in the view of each VLANIF interface to configure ARP entries and reduce the CPU usage. Besides, you are advised to load the latest patch.
