Establishing Redundancy Between Two Service Modules
Guidelines for configuring redundancy between two service modules are provided in the Cisco MGX
8850 (PXM1E/PXM45), Cisco MGX 8950, Cisco MGX 8830, and Cisco MGX 8880 Hardware
Installation Guide, Releases 2 Through 5. To establish redundancy between two service modules, use
the following procedure.
Establish a configuration session using a user name with SUPER_GP privileges or higher.
Step 1
If you have not done so already, set the firmware version for both cards, as described in the
Step 2
Service
Enter the dspcds command to verify that both service modules are in the Active state.
Step 3
Enter the addred command as follows:
Step 4
pop20one.7.PXM.a > addred <redPrimarySlotNum> <redSecondarySlotNum> <redType>
Replace <redPrimarySlotNum> with the slot number of the service module that will be the primary card,
and replace <redSecondarySlotNum> with the slot number of the secondary service module.
Replace <redType> with the number 1 to select 1:1 card redundancy (also called Y-cable redundancy),
or enter 2 to select 1:N redundancy. Each service module type supports only one redundancy type, and
the redundancy types are defined in the Cisco MGX 8850 (PXM1E/PXM45), Cisco MGX 8950, Cisco
MGX 8830, and Cisco MGX 8880 Hardware Installation Guide, Releases 2 Through 5.

One of the two cards can be configured before redundancy is established. If this is the case, the
configured card should be specified as the primary card. Redundancy cannot be established if
the secondary card has active lines. If the secondary card has active lines, you must delete all
ports and down all lines before it can be specified as a secondary card.
If the switch displays the message,
already in use on the specified secondary card. Enter the dnln command to bring down these
lines before re-entering the addred command.
