Table 1 lists optional licenses.
NOTE
To activate POD licenses upon installation, you need to remove all port assignments and
reservations for the license.
Dynamic Ports on Demand
With Dynamic Ports on Demand (DPOD), physical ports are licensed as they come online. In the
Base model port set, the first 24 ports reporting (on a first-come, first-served basis) on boot-up are
assigned licenses. These ports may be any combination of external or internal Ethernet ports. After
all licenses have been assigned, you can manually move those licenses from one port to another,
except for the eight 10-Gbps ports that result when the two 40-Gbps Ethernet ports are configured
in breakout mode.
FlexPort
The FlexPort feature is supported only on the Lenovo Flex System EN4023 10Gb Scalable Switch
by Network OS 5.0.0 and later. This feature allows you to configure the external SFP+ ports as
Ethernet ports or as Fibre Channel (FC) ports. Qualified 10 GbE SFP+ transceivers, 8 Gbps FC
transceivers, or 16 Gbps FC transceivers must be installed in ports to allow Ethernet or FC
configuration. When configuring a mixture of Ethernet and FC ports in a port group, you can
configure mixtures of speeds and protocols as follows:
•
2 Gbps, 4 Gbps, and 8 Gbps FC and 1/10 Gbps Ethernet
•
16 Gbps FC and 10 Gbps Ethernet only
•
2 Gbps, 4 Gbps, 8 Gbps, and 16 Gbps FC (no Ethernet)
This feature allows you to attach FC devices to run encapsulated FC over Ethernet (FCOE) traffic
through the switch. For details on this feature, including configuration procedures, refer to the
Brocade Network OS Layer 2 Switching Configuration Guide .
NOTE
16 Gbps FC transceivers operate at 4 Gbps, 8 Gbps, and 16 Gbps while 8 Gbps FC transceivers
operate at 2 Gbps, 4 Gbps, and 8 Gbps.
NOTE
The FC/FCoE Upgrade License is required to enable the FlexPort feature.
