Configuring Support of 1 port OC-48/ 4 port OC-12/OC-3 + 12 port T1/E1 + 4 port T3/E3 CEM Interface Module
The 1 port OC-48/ 4 port OC-12/OC-3 + 12 port T1/E1 + 4 port T3/E3 CEM Interface Module has 12XDS1, 4XDS3, electrical interfaces, and 4XSFP ports that can provide multiple functions such as 1XOC-48/12/3 and 3XOC-12/3. The maximum speed supported on OCx ports is OC-48. The interface module supports a maximum of 3G CEM traffic.
OCx Port License should be enabled for the configuration.
Restrictions of Feature Support on 4 Port OC48/OC12/OC3 + 12 Port T1/E1 + 4 Port T3/E3 CEM Interface Module
CESoP is not supported.
Mixed mode support, for example, DS1 and E1 or DS3 and E3 or SONET and SDH simultaneously on different ports is not available.
E1/E3, Unidirectional Path Switching Ring (UPSR), and Data Communication Channel (DCC) are not supported.
Multiservice functionality: PPP, MLPPP, FR, and MLFR are not supported.
EoS and EoPDH are not supported.
The IM is only supported on Cisco RSP2 Module.
The configure replace command is not supported on the T1/E1 interface modules.
A combination of T1/T3/SONET with E1/E3/SDH modes are not supported.
The Cisco Software License Activation feature is a set of processes and components to activate Cisco IOS-XE software feature sets by obtaining and validating fee-based Cisco software licenses.You should enable the license only for OCx ports. License is not required for the ports 0-15 (DSx ports).
You should associate a required license to a port. Many licenses can be configured for a port. Only one license can be associated with a port as only one rate can be configured at a time. Other licenses are not required unless rate is changed frequently.
No license is enabled on the port by default. Same port license (OC-3 or OC-12) can be used for Legacy OC-3 IM. A port can be enabled with any one of the following license types:
On each IM, OCx port can be configured on ports 16-19. For example, a maximum of four OC-3 ports can be configured on ports 16-19. A maximum of four OC-12 ports can be configured on ports 16-19. A maximum of one OC-48 port can be configured on ports 16-19.
The free licenses can be associated with the same or different IM ports.
Scenario of IM Re-insertion
When IM is inserted back in the same slot, the IM ports require the licenses based on the configurations.
The available free licenses are used and old configurations are retained.
When free licenses are not available, the controller port moves to "shut" state and the following error message is displayed:
Controller port does not have license so putting it into shut state. Un-shut after enabling license or remove controller port configuration
To remove the "shut" state, perform any one of the following actions:
Remove all the configurations present at rate level and beyond.
Enable the license on the port that has the same rate as that of the configured controller. For example, enable OC3 license for any OC3 configuration to remove the "shut" state.
Thus, port configurations remain intact and controller port re-configuration is not required.
Installing a License
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 http://www.cisco.com/go/license (or you already backed up the license by using the license save command).
To install the license:
enableshow license udi
Convert the PAK to a license by entering the PAK and the UDI into the Cisco Product License Registration portal: http://www.cisco.com/go/licenselicense installstored-location-urlshow license detailend
Enabling a License
Use the platform enable controller Mediatype <slot/bay/port> <port rate> to enable a particular license type on the controller port. Providing a particular license type is mandatory to enable the license on the IM.
This command is not applicable for DSx ports (0-15).
You should configure controller mediatype and controller SONET before enabling the license on the port. License enabling is allowed when the license with the same rate is configured on the port. The configuration fails if the license with a different rate is configured on the port.
