Configuring Support of 1 port OC-48/STM-16 or 4 port OC-12/OC-3 / STM-1/STM-4 + 12 port T1/E1 + 4 port T3/E3 CEM Interface Module

The 1 port OC-48/STM-16 or 4 port OC-12/OC-3 / STM-1/STM-4 + 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.


Note

In addition to support on RSP2 module, the IM is supported on RSP3 from the Cisco IOS XE 16.9.x release.

Restrictions of Feature Support on 4 Port OC48/OC12/OC3 + 12 Port T1/E1 + 4 Port T3/E3 CEM Interface Module

  • 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: MLPPP, FR, and MLFR are not supported.

  • EoS and EoPDH are not supported.

  • The configure replace command is not supported.

  • A combination of T1/T3/SONET with E1/E3/SDH modes are not supported.

  • When IM is used with RSP3 module, then it is not allowed in slots 0 and 1 on chassis.

  • Synchronization Status Message (SSM) is not supported on T3 ports.

Port Licensing

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:

  • OC-3

  • OC-12

  • OC-48

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.

Information About Port Licensing

Scenario of IM Removal

  • All licenses enabled on the IM ports are removed.

  • 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:

    configure terminal
controller mediatype 0/1/19
mode sonet
rate oc3
controller sonet 0/1/19
rate oc3
 license is not enabled for this rate
% Unable to configure this rate.
end
  • 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:

enable
 show 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/​license
license install stored-location-url
show license detail
end

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.

Note

This command is not applicable for DSx ports (0-15).

Note

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.

To enable port licensing:

enable
configure terminal
platform enable controller MediaType 0/4/16 oc3
controller MediaType 0/4/16
mode sonet
exit
controller sonet 0/4/16
rate oc3
exit

Verifying License Configuration

Use the show license detail command to verify the license configuration: 

Router#show license detail
Index: 15 Feature: oc3  Version: 1.0
        License Type: Permanent
        License State: Active, In Use
        License Count: 1/1/0  (Active/In-use/Violation)
        License Priority: Medium
        Store Index: 4
        Store Name: Primary License Storage
#

Disabling a License

Use the no platform enable controller Mediatype <slot/bay/port> <port rate> to disable a particular license type on the controller port.

Note

Disabling a license is not successful if a rate is configured on the controller that requires the license. Hence, you should first remove the controller configuration before disabling the license.

To disable port licensing:

enable
configure terminal
controller sonet 0/4/16
sts-1 1
no vtg 1 t1 1 cem-group 23 unframed
no mode vt-15
controller MediaType 0/4/16
no mode sonet
exit
no platform enable controller MediaType 0/4/16 oc3

Uninstalling a License

To uninstall a license:

enable
configure terminal
no platform enable controller MediaType slot/bay/port OC3
end
license clear feature-name

Enabling T1 Controller


Note

T1/T3 or E1/E3 does not require any license.

To enable T1 controller:

enable
configure terminal
controller mediatype 0/4/0
mode t1
end

Configuring the Controller

To configure T1 interface, use the following commands:

enable
configure terminal
controller mediatype 0/4/0
mode t1
exit
controller t1 0/4/0
clock source internal
framing esf
cablelength short 110
linecode b8zs
no shutdown
exit

Enabling SONET Controller

To enable SONET controller:

enable
configure terminal
controller mediatype 0/0/16
mode sonet
end
