Product: NGAF
Version: 8.0.47
1. Introduction
1.1 Scenario
In a real-world scenario, the connection between the Core Switch and the Firewall consists only of a single line. This leads to a single point of failure and when this connection fails, there will be a downtime on the internal network. To address this issue, we need to aggregate interfaces and in this article, the Sangfor NGAF will be configured to combine the two interfaces.

1.2 Benefits of Aggregated Interface
1) Increase Bandwidth
2) Load balancing
3) Redundancy and High Availability
4) Fault tolerance
5) Improve performance
