FC zoning
The Brocade 8000 CEE switch FC zoning is as follows:
The virtual devices created by the Brocade 8000 CEE switch on behalf of the ENodes are
subject to FC zoning. An ENode is only allowed to access devices in the same zones.
Administrative Domains (ADs) are not supported in the Fabric OS v6.1.2_cee release.
ENodes can access FC devices in the same zones— FC devices that are not in the same zones
cannot be accessed. Zone members can overlap in multiple zones (that is, overlapping zones).
Zoning changes are immediately enforced by hard zoning.
ENodes can access all FC devices with no zoning—ENodes can access all FC devices in the
fabric when cfgdisable is issued.
Field replacement—When a Brocade 8000 CEE switch is replaced in the field, you can perform
a configdownload on a previously saved configuration. The original FCoE port WWNs are
restored. No zoning change is required.
Registered state change notification (RSCN)
The Brocade 8000 CEE switch RSCN operation is as follows:
RSCN events generated in the FC fabric are forwarded to the ENodes. RSCN events generated
on the FCoE side are forwarded to the FC devices.
Device RSCN—An RSCN is generated to all registered and affected members when an ENode
either logs in or logs out of an FCF through any means. An RSCN is generated when an FC
N_port device either logs in or logs out of the FC fabric.
NOTE
When transmitting an RSCN, zoning rules still apply for FCoE devices as the devices are treated
as regular FC N_ports.
VF_port RSCN—An RSCN is generated to all registered members when a VF_port goes online or
offline, causing ENode or FC devices to be added or removed.
Domain RSCN—An RSCN is generated to all registered and affected members when an FC
switch port goes online or offline, causing ENode or FC devices to be added or removed. An
RSCN is generated when two FC switches merge or segment, causing ENode or FC devices to
be added or removed. When FC switches merge or segment, an RSCN is propagated to
ENodes.
Zoning RSCN—An RSCN is generated to all registered and affected members when a zoning
exchange occurs in the FC fabric.
