Configuring Redundancy
The MGX 8260 Media Gateway supports both redundant and non-redundant operation for all cards. With redundancy, the system switches to a protection card if an active card fails.The SCC and DMC don't require user setup for redundant operation; when you have two cards installed they automatically protect each other. To configure redundancy for the NSC or BSC, you define protection pairs. The Cisco MGX 8260 uses 1:N protection for NSCs and 1:1 protection for BSCs.
Viewing Redundancy Pairs
To view redundancy pairs, follow these steps:
Step 1 On the Navigation pane, click Card.
Step 2 Click Redundancy Setup.
The Redundant Slot Configuration screen opens.
Displayed Information
Description
Primary Physical Slot Number
The physical slot for the primary card of the redundancy pair. This slot is active during normal operation.
Secondary Physical Slot Number
The physical slot for the secondary card of the redundancy pair. This slot is in standby during normal operation and protects the primary slot in the event of a primary failure.
Defining Redundant Cards
There are three possible redundancy scenarios:
BSC redundancy
This scenario uses pairs of BSCs configured for 1:1 redundancy.
NSC redundancy without DMC
This scenario requires a redundant back card in the protection NSC slot.
NSC redundancy with DMC
This scenario does not require, and cannot have, a redundant back card.
Adding BSC Redundancy
In order to successfully configure a redundant pair, the following conditions must be true:
The hardware configuration of the two BSCs must be identical
The firmware version of the two BSCs must be identical
The redundant BSC must not have any lines configured
Warning Adding card redundancy interrupts service. Perform this operation during light traffic periods or in a pre-arranged maintenance window.
To configure BSC redundancy, follow these steps:
Step 1 Install a redundant BSC. You can use any available slot from 11 to 16.
Step 2 Add a redundant "Y" cable between all ports on the two cards.
Step 3 Click Cards on the navigation pane, then click Redundancy Setup.
Step 4 On the Redundant Slot Configuration screen, click the + icon.
The Add Card Redundancy form opens.
Step 5 Specify the redundancy pair.
Displayed Information
Description
Primary Physical Slot Number
The physical slot for the primary card of the redundancy pair. This slot is active during normal operation.
Secondary Physical Slot Number
The physical slot for the secondary card of the redundancy pair. This slot is in standby during normal operation and protects the primary slot in the event of a primary failure.
Step 6 Click Add.
Both cards reboot and initialize for redundancy.
Step 7 Return to the Redundant Slot Configuration screen to verify the configuration.
Configuring NSC Redundancy without DMC
To configure NSC redundancy without DMC, follow these steps:
Step 1 Verify that the redundant NSC has a redundancy back card installed and that it is in the standby state. For more information, including the procedure, see the "Configuring Card Parameters" section.
Step 2 Verify that each primary NSC has a T1/E1 back card and is in the active state. For more information, including the procedure, see the "Viewing Card Status" section.
Step 3 Click Cards on the navigation pane, then click Redundancy Setup.
Step 4 On the Redundant Slot Configuration screen, click the + icon.
The Add Card Redundancy form opens:
Step 5 Specify the primary and secondary cards.
Step 6 Click Add.
Both cards reboot and initialize for redundancy.
Step 7 Return to the Redundant Slot Configuration screen to verify the configuration.
Step 8 Configure other redundancy pairs, as necessary. All pairs use the same secondary card.
Configuring NSC Redundancy with DMC
To configure NSC redundancy with DMC, follow these steps:
Step 1 Verify that at least one DMC and DS3 back card is installed in physical slot seven or eight. For the procedure, see the "Viewing Card Status" section.
Step 2 Check the Card Configuration screen to verify that the redundant NSC does not have a redundancy back card installed.
Step 3 Check the Card Configuration screen to verify that each primary NSC does not have a back card and is in the active state.
Step 4 Click Cards on the navigation pane, then click Redundancy Setup.
Step 5 On the Redundant Slot Configuration screen, click the + icon.
The Add Card Redundancy form opens.
Step 6 Specify the primary and secondary cards.
Step 7 Click Add. Both cards reboot and initialize for redundancy.
Step 8 Return to the Redundant Slot Configuration screen to verify the configuration.
Deleting Redundancy
To delete redundancy, follow these steps:
Step 1 Click Cards on the navigation pane.
Step 2 Click Redundancy Setup.
The Redundant Slot Configuration screen opens.
Step 3 Click the - icon on the row with the redundancy pair you want to delete and confirm you action.
The system deletes the redundancy pair and updates the redundancy table.
Invoking a Switchback
The switchover from primary to secondary cards is automatic when a primary card fails. After repairing the failure that caused a switchover, you must manually switch the protection pair back to their original state.
To force a redundancy switchover, follow these steps:
Step 1 On the Navigation pane, click Card.
Step 2 Click All-Cards.
The Physical Slot Configuration screen opens.
Step 3 Click the S icon on the row of the desired card. The system forces a protection switch.
Viewing MSM Configuration
To view MSM type and operational status, follow these steps:
Step 1 On the Navigation pane, click Card.
Step 2 Click MSM-Cards.
The MSM Card screen opens:
Step 3 Interpret the display as follows:
