port on the switch, or the switchDisable and switchEnable commands on the switch, to enable 8
Gbps features.
• When you remove the 8G license, the ports that are online and already running at 8 Gbps are not
disturbed until the port goes offline or the switch is rebooted. The switch ports return to their pre-
licensed state maximum speed of 4 Gbps.
10G licensing
The 10 Gbps FCIP/Fibre Channel license (10G license) enables the following features:
• 10 Gbps access on the 16-Gbps FC ports on Brocade 6510 or 6520 switches, and FC16-32 and
FC16-48 port blades.
• The two 10-GbE ports on the FX8-24 extension blade.
This 10G license is applied as a slot-based license on the FC16-32 and FC16-48 port blades and on the
FX8-24 extension blade; generic rules for adding slot-based licenses apply, as described in Slot-based
licensing on page 24. When this license is applied to a Brocade 6510 or 6520 switch, it is applied to
the whole chassis.
Whether you have a bladed (DCX, DCX-4S, DCX 8510-8, or DCX 8510-4) platform or nonbladed
(Brocade 6510 or 6520) switch, you add the 10G license to the chassis using the licenseAdd
command, as for any license.
For the bladed platforms, you can either allow automatic license assignment, or choose the blades you
want the licenses assigned to manually, as for any slot-based license. Automatic assignment is done
sequentially by slot number, beginning with the lowest numbered slot with an enabled blade that
supports this feature (FX8-24, FC16-32, or FC16-48 blade), and that does not already have the license
applied. If the automatic license assignment does not match your needs, you can use the
licenseSlotCfg --remove and licenseSlotCfg --add commands to remove the license manually from a
slot and assign it to a different slot with an FX8-24, FC16-32, or FC16-48 blade.
The same multiple slot-based 10G license can be applied to a mixture of 16-Gbps blades and FX8-24
blades. For example, if you have a 10G license for two-slot capacity, and you have an FX8-24 blade in
one slot and an FC16-48 blade in a second slot, then the same license can activate the 10GE ports on
the FX8-24 blade and enable 10 Gbps operation on the 10-Gbps FC ports on the FC16-48 blade.
After applying a 10G license to the Brocade 6510 or 6520 chassis or to a 16-Gbps FC blade, you must
also configure the port octet (portCfgOctetSpeedCombo command) with the correct port octet speed
group and configure each port to operate at 10 Gbps (portCfgSpeed command). It is necessary to
configure the port octet because only certain combinations of port speeds are allowed within the port
octet. No license is required for the octet group. If the speed configuration operation succeeds and a
10G-capable SFP is inserted in the port connector, the port will allow operation at 10 Gbps when the
link becomes active at that speed.
Before removing a 10G license from an entire platform (licenseRemove command) or from a specific
blade (licenseSlotCfg --remove command), you must first deconfigure all affected FC ports to no
longer operate at 10 Gbps.
NOTE
An FC port that is operating at 10 Gbps FC speed on a 16-Gbps FC blade or 16-Gbps FC switch does
not need an Extended Fabrics license to be used for FC long distance connectivity. FC ports licensed
and configured to operate at 10 Gbps on a Brocade 6510 or 6520 switch or 16-Gbps FC port blade
cannot interoperate with 10-Gbps FC ports on the M-6140 platform or the FC10-6 blade. The new FC
ports use different protocols and physical connections.
