Licenses
Cisco UCS Fabric Interconnect are equipped with pre-installed port licenses, providing the option to purchase them fully licensed, partially licensed, or add licenses after delivery. The licensing model varies across different Fabric Interconnect series, with some models adopting perpetual software licenses to simplify license management.
Perpetual Licensing for Cisco UCS 6500 Seriesand Cisco UCS X-Series Direct Fabric InterconnectsCisco UCS 6536 Fabric Interconnect (UCS-FI-6536): Starting with release 4.2(3b), all ports and software features are activated through a perpetual software license. No additional license management is required.
Cisco UCS 9108 100G Fabric Interconnect (X-Series Direct): Starting with release 4.3(4b), all ports and software features are similarly activated through a perpetual software license.

Cisco UCS Fabric Interconnects 9108 100G (Cisco UCS X-Series Direct) and UCS-FI-6536 do not use port-based licensing like previous generations of fabric interconnects. |

-
10G_PORT_ACTIVATION_PKG – Licenses used for the first 16 10 GB unified ports on the 6332-16UP

Note
The 10G_PORT_ACTIVATION_PKG and 10G_C_PORT_ACTIVATION_PKG licenses are only valid for the 6332-16UP FIs, and can only be installed on them.
The following licenses are used when S3260 system is connected to FI as appliance (appliance port) or Cisco UCS Manager managed node (server port):

Default Base Licenses |
||
|---|---|---|---|
|
Cisco UCS 9108 100G Intelligent Fabric Module (Cisco UCS X-Series Direct) |
Perpetual software license. This license activates all the ports and software features of Cisco UCS X-Series Direct. |
||
|
Cisco UCS 6536 |
Perpetual software license. This license activates all the ports and software features of 6536 Fabric Interconnect. |
||
|
Cisco UCS 64108 |
For 36 10/25 GB ports (ports 1-96) For 4 40/100 GB ports (ports 97-108). |
||
|
Cisco UCS 6454 |
For 18 10/25 GB ports (ports 1-48) For 2 40/100 GB ports (ports 49-54). |
||
|
Cisco UCS 6332 |
For eight 40 GB ports. |
||
|
Cisco UCS 6332 16UP |
For four 40 GB ports and eight 10 GB ports.
|
||
|
Cisco UCS 6324 |
For 4 non-breakout ports only. The fifth port, which does not include a license, is further broken in to four 10 GB ports. |
Port licenses are not bound to physical ports. When you disable a licensed port, that license is retained for use with the next enabled port. To use additional fixed ports, you must purchase and install licenses for those ports. All ports, regardless of their type (fibre, ethernet) consume licenses if they are enabled.
For breakout capable ports available in the 6332 and the 6332-16UP platforms, 40 GB licenses remain applied to the main port even if that port is a breakout port, and that port continues to consume only one 40 GB license.
![]() Important |
Licenses are not portable across product generations. |
Each Cisco UCS 6324 Fabric Interconnect comes with a factory installed port license that is shipped with the hardware. The C-direct port license is factory installed with a grace period, measured from first use of the port, and can be used for Cisco UCS rack servers. If multiple ports are acting within grace periods, the license is moved to the port whose grace period is closest to expiring.
Grace Period
If you attempt to use a port that does not have an installed license, Cisco UCS initiates a 120 day grace period. The grace period is measured from the first use of the port without a license and is paused when a valid license file is installed. The amount of time used in the grace period is retained by the system.
![]() Note |
Each physical port has its own grace period. Initiating the grace period on a single port does not initiate the grace period for all ports. |
If a licensed port is unconfigured, that license is transferred to a port functioning within a grace period. If multiple ports are acting within grace periods, the license is moved to the port whose grace period is closest to expiring.
High Availability Configurations
To avoid inconsistencies during failover, we recommend that both Fabric Interconnects in the cluster have the same number of ports licensed. If symmetry is not maintained and failover occurs, Cisco UCS enables the missing licenses and initiates the grace period for each port being used on the failover node.
