HOWTO: fortimail redundant members

In this blog we will look at the creation of a  redundant member in a fortimail appliance.

1^st off the fortimail does not offer any type of  LACP or any link-aggregation it allows for  redundant link paths but only one of the link are used. To created a  redundant link you need to follow these simple steps and rules

1.     remove all allowaccess and ip_address off  the selected ports

2.     ensure the ports are not setup as  dhcp

3.     create a new interface ( virtual ) and select  redundant

4.     provide a simple name for this interface

5.     add the selected ports for the redundant members

Reviewing the creation

The benefits of a redundant interface; The ability to eliminate a single path failure”. You will need to cable the  2 interfaces to 2 unique switches or blades to eliminate a single failure. A stack switch  would be ideal imho.

Once you have the interface configured, you can assign an address and use it like any real interface.
