Chapter 4 Preparing Service Modules for Communication
Establishing Redundancy Between Two Service Modules
Unknown line module back card present
cnfcdmode: Do you want to proceed (Yes/No)? y
After you set the interface type and service, the card resets. You can check the status with the dspcd
<slot> command. You can verify that the cnfcdmode command has been run by looking at the Inserted
Card row of the dspcd display.
Before MPSM-8-T1E1 configuration, the Inserted Card row displays the generic name MPSM-8-T1E1.
After configuration, the generic name changes to a specific name such as MPSM-8T1-FRM.
Table 4-2 lists the card names and what they mean when they appear in the dspcd and dspcds command
displays. While the card is resetting, the status will be Empty Resvd. When the reset is complete and the
card is ready for provisioning, the status changes to Active.
Configuring MPSM-T3E3-155 and MPSM-16-T1E1 Interfaces and Services
The MPSM-T3E3-155 card is set to the Active/Active state during initialization using the setrev
command. Use the MPSM cnfcdmode command to specify the interface type when using the
BNC-3-T3E3 backcard only. (This card supports simultaneous ATM and Frame Relay services.)
The MPSM-16-T1E1 card is also set to the Active/Active state during initialization (using the setrev
command with a specified service). When using a backcard that supports both T1 and E1 interfaces, use
the MPSM cnfcdmode command to specify the interface type. (Setting the service type is done during
initialization using the setrev command.)
For details on initializing the MPSM cards, see “Initializing Service Modules”. For details on
configuring the MPSM card interfaces and services, refer to the Cisco ATM and Frame Relay Services
(MPSM-T3E3-155 and MPSM-16-T1E1) Configuration Guide and Command Reference for MGX
Switches, Release 5.1 for more details.
Establishing Redundancy Between Two Service Modules
Guidelines for configuring redundancy between two service modules are provided in the Cisco MGX
8800/8900 Hardware Installation Guide, Releases 2 - 5.1. To establish redundancy between two service
modules, use the following procedure.
Step 1 Establish a configuration session using a user name with SUPER_GP privileges or higher.
