Two clusters sharing the same VLAN

This assume you using CCP (cluster control protocol) in broadcast mode

Can be verified while running : #cphaprob -a if

On cluster A
# fw ctl set int fwha_mac_magic 250
# fw ctl set int fwha_mac_forward_magic 251

On cluster B:
# fw ctl set int fwha_mac_magic 240
# fw ctl set int fwha_mac_forward_magic 241

not sure the above commands are “reboot persitent” (I did not test it) so the change can be implemented in : $FWDIR/boot/modules/fwkern.conf

example :

[Expert@toto]# cat /opt/CPsuite-R65/fw1/boot/modules/fwkern.conf
fwha_mac_magic=250
fwha_mac_forward_magic=251
