Your software release may not support all the features documented in this module. For the latest feature information and caveats, see the release notes for your platform and software release.

The optical modules 4-Port OC3/STM-1 or 1-Port OC12/STM-4 delivers four active ports of OC-3 interface module (IM) or Synchronous Transport Module level 1 (STM-1) connectivity, or one active port of OC-12 IM or STM-4 connectivity, on the Cisco ASR 903 Router. Licensing is applicable to these ports on the interface modules.
The benefits of licensing these ports are:
Pay-as-you-grow model to enhance the ports by purchasing licenses as required.
Ability to shift license from one port to another.
Ability to release a license when the interface module is removed from a slot and reinstall the license when inserted again.
Support for high availability and OIR of interface modules.
OC-3 and OC-12 Interface Module Online Insertion and Removal (OIR)
If an OIR is performed on the enabled port or controller of the interface module, the license used by the interface module is released. When the interface module is inserted again, the license which was valid before the OIR is re-enabled (assuming that there are non-zero usable ports).
OC-3 and OC-12 Interface Module Stateful Switchover (SSO)
If the license is installed on an active port and enabled on the active RSP module, the license information is synchronized with the standby RSP module. On SSO, the license ports enabled on the active RSP are activated on the standby RSP module.
An port license ISSU upgrade from an unsupported release to a supported release may impact the traffic flow on the router. If the controllers before the ISSU are in UP state, after an upgrade the controllers might remain in DOWN state, until the license in installed and enabled on the ports
Reload of Cisco ASR 903
A router reload may not be required after the license in installed on the ports. However, if the router is reloaded, the ports that are enabled prior to the reload will retain the license and configuration.
Installing and Upgrading Licenses on the OC-3 and OC-12 Interface Modules
Before You Begin
Read and understand the license activation process concepts in the in the “Cisco IOS Software Activation Conceptual Overview” module.
To install or upgrade a license by using the
license install command, you must have already received the license file from the Cisco Product License Registration portal at
(or you already backed up the license by using the
license save command).
If you use Microsoft Entourage and receive the license file from Cisco in an e-mail attachment, the license file will contain UTF-8 marking. These extra bytes in the license file cause it to be unusable during license installation. To work around this issue, you can use a text editor to remove the extra characters and then install the license file. For more information about UTF-8 encoding, go to this URL:
The installation process does not install duplicate licenses. This message appears when duplicate licenses are detected:
