The Link Aggregation Groups (LAG) functionality allows you to group two or more ports on your SD-WAN appliance to work together as a single port. This ensures increased availability, link redundancy, and enhanced performance.

Citrix SD-WAN supports simple LAG (ACTIVE-BACKUP). The 802.3ad LACP protocol based negotiations are not supported in the current release. At any time only one port is active and the other ports are in backup mode. The active and backup supports rely on the Data Plane Development Kit (DPDK) package for LAG functionality. The LAG functionality is available only on the following DPDK supported platforms:

Citrix SD-WAN 110 SE
Citrix SD-WAN 210 SE
Citrix SD-WAN 410 SE
Citrix SD-WAN 1100 SE/PE
Citrix SD-WAN 4000, 4100, and 5100 SE
Citrix SD-WAN 6100 SE
Citrix SD-WAN 2100 SE

Note

The LAG functionality is not supported on VPX/VPXL platforms.

You can create a maximum of four LAGs with a maximum of four ports grouped in each LAG on the Citrix SD-WAN appliances.

Note

For Citrix SD-WAN 210 and 410 appliances, you can create only one LAG with a maximum of three ports grouped in it.

To configure Link aggregation groups, in the Configuration Editor, navigate to Sites > Link Aggregation Groups. You can view all the available physical ports and Ethernet interfaces. Click + to create a LAG.

Add link aggregation groups

Select the member ports, and click Apply. Once the ports are added to the LAG, you can see only the LAGs in the Interface Group instead of the member ports.

Interface groups

You can create virtual interfaces using LAGs and these interfaces are further used to configure LAN/WAN links and HA.

Note

The Link State Propagation (LSP) feature is not supported, if LAGs are used as Ethernet interfaces in Interface Groups.

You can view the active and standby LAG ports, navigate to Configuration > Appliance Settings > Network Adapters > Ethernet.

Note

You cannot change settings for individual member ports, any configuration changes made to the LAG, is automatically pushed to the member ports.
