The following kernel parameters are set (either on-the-fly, or permanently via $FWDIR/boot/modules/fwkern.conf file), which conflict with each other:
- The ARP Request is sent from a warp interface from the Standby member to the network.
- The Standby member intercepts the ARP Request and sends it directly to the Active member by modifying the destination MAC address in Ethernet header.
- The Active member then sends the ARP Request to the network.
- Upon receiving the ARP Reply, the Active member resends the ARP Reply to all the other members.

||ARP packets are resent to other cluster members in "unicast"
||Refer to sk94564
This parameter cannot be set on-the-fly with "fw ctl set int" command.
Only permanently via $FWDIR/boot/modules/fwkern.conf file.
||Active cluster member will not forward ARP Reply packets to other peer members
||Refer to sk98417
Clarification: The above values of kernel parameters cause the Active member not to forward ARP Replies to other members.
