• Cisco UCS 6296 fabric interconnect—pre-installed licenses for the first eighteen unified ports enabled
in Cisco UCS Manager. Expansion modules come with eight licenses that can be used on the expansion
module or the base module.
The eight default licenses that come with a 6200 series fabric interconnect expansion module can be used
to enable ports on the base module, but will travel with the expansion module if it is removed. Upon
removal of an expansion module, any default expansion module licenses being used by the base module
are removed from the ports on the base module, resulting in unlicensed ports.
Note
Port licenses are not bound to physical ports. When you disable a licensed port, that license is then retained
for use with the next enabled port. If you want to use additional fixed ports, you must purchase and install
licenses for those ports.
Licenses are not portable across product generations. Licenses purchased for 6100 series fabric interconnects
cannot be used to enable ports on 6200 series fabric interconnects or vice-versa.
Important
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.
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.
Note
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.

The host ID is also known as the serial number.
