Fibre Channel port security prevents unauthorized Fibre Channel devices and switches from logging into the fabric. This protects the fabric from accidents, malicious intent or attacks such as WWN identity spoofing. It’s configured on a per-VSAN basis.
Everything covered here can be found in this configuration guide:
You have a few options to choose from when configuring Port Security:
1. Configure with auto-learning and CFS distribution
2. Configure with auto-learning without CFS distribution
3. Configure with manual database
The first method is definitely most practical, as you can configure once, learn the current environment, and use Cisco Fabric Services (CFS) to distribute throughout the fabric. I’ll be following this method in this blog post, feel free to follow along. Also added a quick template at the bottom.
