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.
