As a matter of fact, we tried polling on the backup firewall yesterday with the following kernel options: options DEVICE_POLLING options HZ=1000 This had disastrous results. First, our LAN and DMZ interfaces (bce0 and 1) do not support polling, so no change here. Second, the WAN interface (igb0) supports polling but that caused problems with carp0 and the physical interface resetting itself for god knows what reason: carp0: link state changed to DOWN carp0: INIT -> BACKUP igb0: link state changed to UP carp0: link state changed to DOWN carp0: link state changed to UP carp0: MASTER -> BACKUP (more frequent advertisement received) carp0: link state changed to DOWN carp0: link state changed to UP igb0: Watchdog timeout -- resetting igb0: Queue(1) tdh = 57, hw tdt = 57 igb0: TX(1) desc avail = 967,Next TX to Clean = 0 igb0: link state changed to DOWN carp0: link state changed to DOWN carp0: INIT -> BACKUP igb0: link state changed to UP carp0: link state changed to DOWN carp0: link state changed to UP carp0: link state changed to DOWN igb0: Watchdog timeout -- resetting igb0: Queue(3) tdh = 5, hw tdt = 5 igb0: TX(3) desc avail = 1019,Next TX to Clean = 0 igb0: link state changed to DOWN igb0: link state changed to UP igb0: Watchdog timeout -- resetting igb0: Queue(2) tdh = 53, hw tdt = 53 igb0: TX(2) desc avail = 971,Next TX to Clean = 0 igb0: link state changed to DOWN igb0: link state changed to UP igb0: Watchdog timeout -- resetting igb0: Queue(2) tdh = 19, hw tdt = 19 igb0: TX(2) desc avail = 1005,Next TX to Clean = 0 igb0: link state changed to DOWN igb0: link state changed to UP _______________________________________________ freebsd-pf@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-pf To unsubscribe, send any mail to "freebsd-pf-unsubscr...@freebsd.org"
