Getting started and SLBC Basics
- SLBC licensing

  - Certificates
- Changing FortiController interface configurations
- Quick SLBC cluster setup
- Managing the cluster
- Monitoring the cluster
- Worker communication with FortiGuard
- Basic cluster NAT/Route mode configuration
  - Using the GUI to configure NAT/Route mode
  - Using the CLI to configure NAT/Route mode
- Primary unit (master) selection
  - Selecting the primary FortiController (and the primary chassis)
  - Selecting the primary worker

  - Adding one or more new workers
  - Removing a worker from a cluster
- Adding link aggregation (LACP) to an SLBC cluster (FortiController trunks)
  - Adding an aggregated interface
- Individual FortiAnalyzer settings on each worker
  - Configuring different FortiAnalyzer settings for each SLBC worker
  - Configuring different FortiAnalyzer settings for each worker and for the root VDOM of each worker
- Adding VLANs
  - Adding a VLAN to a FortiController interface

  - Assumptions
  - Conversion steps
- Updating SLBC firmware
Configuring communication between FortiControllers
- Changing the base control subnet and VLAN

Changing load balancing settings
- Tuning TCP load balancing performance (TCP local ingress)
- Tuning UDP load balancing (UDP local ingress and UDP remote/local session setup)
- Changing the load distribution method
- TCP and UDP local ingress session setup and round robin load balancing
