Each link aggregation interface can have one or more physical interface members. To specify a physical interface on your XTM device for use in a link aggregation interface, you must first configure the physical interfaces and select Link Aggregation as the interface type. You can then create the link aggregation interface and add one or more physical interfaces of the link aggregation type as the link aggregation members.
If you change an interface type from External to Link Aggregation, any 1 to 1 NAT rules previously associated with the external interface are automatically removed.
For information about link aggregation modes, see About Link Aggregation.
If you choose Static or Dynamic mode, your connected switch or router must also support and be configured to use the same mode.
For a Trusted, Optional, or Custom interface:
Type the IPv4 interface private IP address in slash notation. For more information about private IP addresses, see About Private IP Addresses.
To enable and configure IPv6, select the IPv6 tab. For information about the IPv6 settings, see Enable IPv6 for a Trusted or Optional Interface.
For an External interface:
To enable and configure IPv6, select the IPv6 tab. For information about the IPv6 settings, see Enable IPv6 for an External Interface.
IPv6 on a link aggregation interface is supported in Fireware XTM v11.9 and higher.
For a Bridge interface:
Select the network bridge interface you want to add this link aggregation interface to. You must assign this interface to a Bridge. For more information, see Assign a Network Interface to a Bridge.
For a VLAN interface:
Select the tagged or untagged VLANs you want to add this link aggregation interface to. You must assign this interface to a VLAN. For more information, see Assign Interfaces to a VLAN.
The network interface settings apply to all physical interfaces assigned to this link aggregation interface. For more information, see Network Interface Card (NIC) Settings.
Physical interfaces that are members of a link aggregation interface must support the same link speed. On XTM 505, 510, 520, or 530 devices, interface 0 (Eth0) supports a lower maximum link speed than the other interfaces. If you use Eth0 as a member of a link aggregation interface on these models, you must set the Link Speed to 100 Mbps or lower in the link aggregation interface configuration and on the connected network switches.
Unlike a physical interface configuration, you cannot configure Traffic Management, QoS, or static MAC/IP address binding in the interface advanced settings. A link aggregation interface does not support those features.
If you configure a link aggregation interface to use dynamic or static link aggregation, you must configure the switch that these interfaces connect with to use the same link aggregation mode and link speed. Then, you can connect the cables from the member interfaces on the XTM device to the other network device.
If the link aggregation interface uses Active-backup mode, you do not need to enable link aggregation on your connected switches or routers.
For more information about link aggregation network modes, see About Link Aggregation.
After you configure link aggregation settings, you can see a summary of the settings for each link aggregation configuration on the Link Aggregation page. Select Network > Link Aggregation.
The columns show information about each link aggregation interface.
The interface name. You can use this name in policies just as you would any other interface name.
The interface type. Link aggregation interfaces can be Trusted, External, Optional, Bridge or VLAN.
The interface IPv4 address. This column shows DHCP or PPPoE client for an external interface configured to get an IP address from a DHCP or PPPoE server.
The interface IPv6 address. This column shows DHCP or PPPoE client for an external interface configured to get an IP address from a DHCP or PPPoE server.
The interface numbers of the physical interfaces that are members of this link aggregation interface.
From the Link Aggregation page, you can edit or remove a link aggregation interface. When you remove a link aggregation interface, the member interfaces are still set to type Link Aggregation, but they are no longer assigned to any link aggregation interface.
