Fibre Channel Configuration
Configuration Guidelines
Example 1: NPV Gateway
© Copyright Lenovo 2015
In Lenovo N/OS 8.3, consider the following when configuring Fibre Channel on the
CN4093:
Up to 12 Fibre Channel networks (on separate VLANs) are supported.
Only one Fibre Channel VLAN can operate in full fabric mode at any given time.
All others can operate as NPV gateways.
Only Omni Ports (EXT11-EXT22) can be placed in Fibre Channel mode. All other
ports operate in Ethernet mode, which may participate in Fibre Channel
networks as FCoE nodes.
At least one Omni Port is required to operate in Fibre Channel mode in each
Fibre Channel VLAN.
Zones and zonesets apply only to a VLAN in full fabric mode. Up to 4 zonesets
may be configured, but only 1 can be active at any given time. The CN4093
supports up the 64 zones per zoneset, each with up to 20 member devices.
However, when an FC alias is used, only 10 devices can be members of a zone.
In a stack setup, the full fabric mode or NPV gateway mode is bound to a single
switch, as determined by the external FC ports in the VLAN. All FC ports
belonging to a Fibre Channel VLAN must be part of the same switch. Both full
fabric mode and NPV mode can be configured on the Master as well as the
Backup switch. For details on configuring a stack, see
In this example, the CN4093 operates as an NPV gateway:

Network
The switch connects to FCoE node ports to an external Fibre Channel full fabric
switch. Because multiple nodes will share the CN4093 uplinks, the network must
be configured as an NPV gateway.
Note: Up to 12 Fibre Channel VLANs can be configured on the switch at any given
time, any or all of which can be configured as NPV gateways.
