However, it is recommended that the physical cabling is in place before the LinkAggregation
object is activated and saved. This will provide the behavior which is expected from the feature
and is particularly relevant if negotiated aggregation (LACP) is used.
Setup with High Availability
When using link aggregation with HA, the connections from the Ethernet ports on each security
gateway in the HA cluster can connect to the same or different switches. However, if using the
same switch, the switch must be configured so that the connections from each security gateway
are kept separate by creating two link aggregation groups in the switch.
Setting the MTU Value
It is possible to set a specific MTU property value on a link aggregation interface. However, this
value will not be used on one of the aggregated Ethernet interfaces if the individual Ethernet
interface MTU property is set to a value that is lower than the link aggregation MTU. This is true
regardless if the mode is static or negotiated (LACP).
Example 3.15. Link Aggregation
In this example, the Ethernet interfaces If1 and If2 will become part of a single LinkAggregation
object called la_if1_if2. It is assumed that this new object will have the pre-defined IPv4 address
object la_if1_if2_ip assigned to it and this address belongs to the network la_if1_if2_net.
The switch the link is connecting is capable of a link negotiation.

• Name: la_if1_if2
• Distribution Algorithm: DestinationIP
• Mode: LACP
• IP address (IPv4): la_if1_if2_ip
• Network (IPv4): la_if1_if2_net
