Fibre Channel Zoning

Fabric-level access control that defines which FC devices can communicate with each other.

Definition

Zones group WWPNs or switch ports; zones are placed in zonesets and one zoneset is active per VSAN or fabric. Single-initiator, single-target zoning (or Cisco smart zoning) is best practice. Soft zoning uses WWNs while hard zoning is enforced in hardware.

Example

zone name ESX01_ARRAYA vsan 10 with member pwwn entries for the host and array ports.

Exam tip

Activate the zoneset after changes; an edited but inactive zoneset has no effect.
