Working with the GARP Chunk Mechanism
Check Point Maestro R80.20SP Administration Guide | 68
Whenever the iteration is finished sending GARP Requests for the entire list, it waits
N
HTUs and sends the
GARP Requests again.
The time between the iterations can be configured with these kernel parameters:
Kernel Parameter
Description
fwha_periodic_send_garps_
interval1
The default value is 1 HTU (0.1 second).
The Security Group sends the GARP immediately after failover.
Important
- Do not change this value.
fwha_periodic_send_garps_
interval2
The default value is 10 HTUs (1 second).
After the iteration sends the GARP list, it waits for this period of
time and sends it again.
fwha_periodic_send_garps_
interval3
The default value is 20 HTUs (2 seconds).
After the iteration sends the GARP list, it waits for this period of
time and sends it again.
fwha_periodic_send_garps_
interval4
The default value is 50 HTUs (5 seconds).
After the iteration sends the GARP list, it waits for this period of
time and sends it again.
fwha_periodic_send_garps_
interval5
The default value is 100 HTUs (10 seconds).
After the iteration sends the GARP list, it waits for this period of
time and sends it again.
To change an interval, run:
# g_fw ctl set int fwha_periodic_send_garps_interval<
N
> <
Value
>
To apply the intervals, run:
# g_fw ctl set int fwha_periodic_send_garps_apply_intervals 1
Verification
To send GARP Requests manually, on the SMO, run:
# g_fw ctl set int test_arp_refresh 1
This causes GARP Requests to be sent (same as was failover).
To debug:
# g_fw ctl zdebug -m c ch_conf | grep fw_refresh_arp_proxy_on_
failover
Important
- To make the above configuration permanent (to survive reboot), add the
applicable kernel parameters to the
fwkern.conf
file with this command:
update_conf_file fwkern.conf <
parameter
>=<
value
>
.
