Cisco Systems MGX 8230 manual Redundancy for Service Modules, Hot Standby, 1N Redundancy

Chapter 1 Introducing the MGX 8230

Summary of MGX 8230 Cards and Modules

Redundancy for Service Modules

Service modules can have either 1:1 redundancy or 1:N redundancy.

Refer to the CiscoView user documentation for instructions on using the CiscoView application to configure redundancy.

1:1 Redundancy

For 1:1 redundancy, place the card sets in adjacent slots and connect the appropriate Y-cable to the paired ports on the active and standby cards. Applicable service modules are:

•MGX-FRSM-2CT3

•MGX-FRSM-2T3E3

•MGX-FRSM-HS2

Hot Standby

For hot standby, place the card sets in the same shelf and connect the appropriate Y-cable to the paired ports on the active and hot standby cards. The hot standby card will automatically configure itself to match the configuration of the primary card. This process may take up to eight minutes. After the configuration transfer process is completed, the transfer from the primary to the hot standby card takes less that one second regardless of the number of connections. Any subsequent changes to the primary card are automatically transferred to the hot standby card configuration so the two cards maintain the same configuration. Refer to the “Redundancy for Service Modules” section on page 1-16for instructions for setting up a redundant pair.

Applicable service modules are:

•MGX-FRSM-2CT3

•MGX-FRSM-2T3E3

•MGX-FRSM-HS2

To determine the hot standby status of the system, use the command dsphotstandby.

1:N Redundancy

For 1:N redundancy, an MGX Service Resource Module-3T3 (MGX-SRM-3T3/C) card set is necessary. This card set supports 1:N redundancy for the following service modules:

•MGX-AUSM-8T1/B

•MGX-AUSM-8E1/B

•AX-FRSM-8T1

•AX-FRSM-8E1

•AX-CESM-8T1

•AX-CESM-8E1

•MGX-VISM-8T1

•MGX-VISM-8E1
