To configure the FortiGate-620B units for HA operation
1 Power on the first FortiGate-620B unit and log into the web-based manager.
2 On the System Information dashboard widget, beside Host Name select Change.
3 Enter a new Host Name for this FortiGate unit.
4 Select OK.
5 Go to System > Config > HA and change the following settings.
Since port3 and port4 will be used for a redundant interface, you must change the HA heartbeat configuration.
New Name 620_ha_1
Mode Active-Passive
Group Name example6.com Password HA_pass_6 Heartbeat Interface
Enable Priority
port5 Select 50
port6 Select 50
6 Select OK.
The FortiGate unit negotiates to establish an HA cluster. When you select OK you may temporarily lose connectivity with the FortiGate unit as the HA cluster negotiates and the FGCP changes the MAC address of the FortiGate unit interfaces (see “Cluster virtual MAC addresses” on page 205). The MAC addresses of the FortiGate-620B interfaces change to the following virtual MAC addresses:
• port1 interface virtual MAC: 00-09-0f-09-00-00
• port10 interface virtual MAC: 00-09-0f-09-00-01
• port11 interface virtual MAC: 00-09-0f-09-00-02
• port12 interface virtual MAC: 00-09-0f-09-00-03
• port13 interface virtual MAC: 00-09-0f-09-00-04
• port14 interface virtual MAC: 00-09-0f-09-00-05
• port15 interface virtual MAC: 00-09-0f-09-00-06
• port16 interface virtual MAC: 00-09-0f-09-00-07
• port17 interface virtual MAC: 00-09-0f-09-00-08
• port18 interface virtual MAC: 00-09-0f-09-00-09
• port19 interface virtual MAC: 00-09-0f-09-00-0a
• port2 interface virtual MAC: 00-09-0f-09-00-0b
• port20 interface virtual MAC: 00-09-0f-09-00-0c
• port3 interface virtual MAC: 00-09-0f-09-00-0d
• port4 interface virtual MAC: 00-09-0f-09-00-0e
• port5 interface virtual MAC: 00-09-0f-09-00-0f
• port6 interface virtual MAC: 00-09-0f-09-00-10
• port7 interface virtual MAC: 00-09-0f-09-00-11
• port8 interface virtual MAC: 00-09-0f-09-00-12
• port9 interface virtual MAC: 00-09-0f-09-00-13
To reconnect sooner, you can update the ARP table of your management PC by deleting the ARP table entry for the FortiGate unit (or just deleting all arp table entries).
You may be able to delete the arp table of your management PC from a command prompt using a command similar to arp -d.
You can use the get hardware nic (or diagnose hardware deviceinfo nic) CLI command to view the virtual MAC address of any FortiGate unit interface. For example, use the following command to view the port1 interface virtual MAC address (Current_HWaddr) and the port1 permanent MAC address (Permanent_HWaddr):
get hardware nic port1 .
. .
MAC: 00:09:0f:09:00:00
Permanent_HWaddr: 02:09:0f:78:18:c9 .
. .
7 Power off the first FortiGate unit.
8 Repeat these steps for the second FortiGate unit.
Set the second FortiGate unit host name to:
To connect the cluster to the network
1 Connect the port1 and port2 interfaces of 620_ha_1 and 620_ha_2 to a switch connected to the Internet.
Configure the switch so that the port1 and port2 of 620_ha_1 make up a redundant interface and port1 and port2 of 620_ha_2 make up another redundant interface.
2 Connect the port3 and port4 interfaces of 620_ha_1 and 620_ha_2 to a switch connected to the internal network.
Configure the switch so that the port3 and port4 of 620_ha_1 make up a redundant interface and port3 and port4 of 620_ha_2 make up another redundant interface.
3 Connect the port5 interfaces of 620_ha_1 and 620_ha_2 together. You can use a crossover Ethernet cable or regular Ethernet cables and a switch.
4 Connect the port5 interfaces of the cluster units together. You can use a crossover Ethernet cable or regular Ethernet cables and a switch.
5 Power on the cluster units.
The units start and negotiate to choose the primary unit and the subordinate unit. This negotiation occurs with no user intervention and normally takes less than a minute.
When negotiation is complete the cluster is ready to be configured for your network.
To view cluster status
Use the following steps to view the cluster dashboard and cluster members list to confirm that the cluster units are operating as a cluster.
1 View the system dashboard.
The System Information dashboard widget shows the Cluster Name (example5.com) and the host names and serial numbers of the Cluster Members. The Unit Operation widget shows multiple cluster units.
2 Go to System > Config > HA to view the cluster members list.
The list shows two cluster units, their host names, their roles in the cluster, and their priorities. You can use this list to confirm that the cluster is operating normally.
To troubleshoot the cluster configuration
If the cluster members list and the dashboard do not display information for both cluster units the FortiGate units are not functioning as a cluster. See “Troubleshooting HA clusters” on page 110 to troubleshoot the cluster.
To add basic configuration settings and the redundant interfaces Use the following steps to add a few basic configuration settings.
1 Log into the cluster web-based manager.
2 Go to System > Admin > Administrators.
3 For admin, select the Change Password icon 4 Enter and confirm a new password.
5 Select OK.
New Name 620_ha_2
6 Go to Router > Static and temporarily delete the default route.
You cannot add an interface to a redundant interface if any settings (such as the default route) are configured for it.
7 Go to System > Network > Interface and select Create New to add the redundant interface to connect to the Internet.
8 Set Type to Redundant Interface and configure the redundant interface to be connected to the Internet:
9 Select OK.
10 Select Create New to add the redundant interface to connect to the internal network.
11 Set Type to Redundant Interface and configure the redundant interface to be connected to the Internet:
Name Port1_Port2
Physical Interface Members Selected Interfaces port1, port2 IP/Netmask 172.20.120.141/24
Name Port3_Port4
Physical Interface Members Selected Interfaces port3, port4 IP/Netmask 10.11.101.100/24 Administrative Access HTTPS, PING, SSH
12 Select OK.
The virtual MAC addresses of the FortiGate-620B interfaces change to the following.
Note that port1 and port2 both have the port1 virtual MAC address and port3 and port4 both have the port3 virtual MAC address:
• port1 interface virtual MAC: 00-09-0f-09-00-00
