Cisco Systems MGX 8230 manual Configuring Redundancy Through the Distribution Bus

Chapter 6 Card and Service Configuration

Service Resource Module

•redSecondarySlotNum Slot number that contains the secondary card of the card

pair, in the ranges 4–6 or 11–13.

• RedType is a number that specifies the type of redundancy.

•Enter a 1 to specify 1:1 redundancy.

•Enter a 2 to specify 1:N redundancy. Only an SRM can support 1:N redundancy.

Step 2 Check the redundancy status for all cards by using dspred.

To remove redundancy, use delred.

Configuring Redundancy Through the Distribution Bus

Redundancy by way of the distribution bus applies to T1 channels you linked for bulk distribution. For

aredundancy configuration on the MGX-SRM-3T3/C that utilizes the distribution bus:

•No back cards are necessary.

•The MGX-SRM-3T3/C can support multiple switchovers for different 1: N redundancy groups.

•Slots 9, 10, 15, or 26 are not supported.

Before you specify redundancy with bulk distribution, linkage must exist between a T3 line on the MGX-SRM-3T3/C and a primary service module with the T1 lines. No linkage should exist on the secondary service module. To configure redundancy through the CLI:

Step 1 Execute addred on the active PXM1:

addred <redPrimarySlotNum> <redSecondarySlotNum> <RedType>

where:

•redPrimarySlotNum is slot number of the slot containing the primary card. Permissible slot numbers are in the range 1–6, 11–14, 17–22, and 27–30.

•redSecondarySlotNum is slot number of the slot containing the secondary card of the card pair. Permissible slot numbers are in the range 1–6, 11–14, 17–22, and 27–30.

• RedType	is a number that specifies the type of redundancy. Enter
	a 1 to specify 1:1 redundancy. Enter a 2 to specify 1:N
	redundancy. Only an SRM can support 1:N redundancy.

Step 2 Check the redundancy status for all cards by using dspred.

To remove redundancy, use delred.
