Zoning considerations
When encryption is implemented, frames sent between a host and a target LUN are redirected to a
virtual target within an encryption switch or blade. Redirection zones are created to route these
frames. When redirection zones are in effect, direct access from host to target should not be
allowed to prevent data corruption.
Set zone hosts and targets together before configuring them for encryption. Redirection zones are
automatically created to redirect the host-target traffic through the encryption engine, but
redirection zones can only be created if the host and target are already zoned.
Setting default zoning to no access
Initially, default zoning for all Brocade Encryption Switches is set to All Access. The All Access
setting allows the Brocade Encryption Switch and DCX Backbone to join the fabric and be
discovered before zoning is applied. If there is a difference in this setting within the fabric, the
fabric will segment.
Before committing an encryption configuration in a fabric, default zoning must be set to No Access
within the fabric. The No Access setting ensures that no two devices on the fabric can
communicate with one another without going through a regular zone or a redirection zone.
1. Check the default zoning setting. Commonly, it will be set to All Access.
