LAG Configuration Summary

Tunnel Concentrator supports Link Aggregation (LAG) for the data ports. LAG interfaces increase link throughput and provide redundancy in case of a link failure.

To deploy the feature on Tunnel Concentrator, you must first configure LAG for Universal Compute Platform. The LAG port members that you configure on Universal Compute Platform get synced to Tunnel Concentrator automatically. To complete the setup, configure Tunnel Concentrator to use the LAG port. Once the feature is configured, LACP LAG on Universal Compute Platform creates and manages the aggregated link, and static LAG from Tunnel Concentrator runs on that link.

Note

Tunnel Concentrator supports static LAG only. Universal Compute Platform supports LACP LAG only.

To configure LAG, assign the settings in the following table. For step 2, complete only the configuration for your management application.

Table 1. LAG Configuration Summary
Step	Task	For a procedure...
1	On the Universal Compute Platform host: Configure LACP LAG for the data interface.	"Configure LAG Ports" in Universal Compute Platform User Guide
2	Configure static LAG for Tunnel Concentrator from your management application. Make sure the static LAG configuration matches the host's LAG configuration. On ExtremeCloud‌ IQ, assign the LAG port to the Tunnel Concentrator service: Set Tunnel Port to the LAG port (required setting). Set Bridge Port to the LAG port (optional setting). On ExtremeCloud IQ Controller, assign the LAG port to Tunnel Concentrator device: Under GRE/IPSec tunnel termination point, set Port to the LAG port (required setting). Under GRE/IPSec bridge interface, set Port to the LAG port (optional setting).	For ExtremeCloud‌ IQ: Configure Tunnel Concentrator Service For ExtremeCloud IQ Controller: Configure Tunnel Concentrator

The following image shows the Tunnel Concentrator LAG configuration when ExtremeCloud IQ is the management entity. From the Tunnel Concentrator Service window, set Tunnel Port to the LAG port that you configured on Universal Compute Platform. Optionally, you can also set Bridge Port to the LAG port, but it's not required.
