Configuring Redundancy

The Cisco MGX 8260 Media Gateway supports both redundant and nonredundant operation for all cards. The SCC and DMC do not require user setup for redundant operation. To configure redundancy for the NSC or BSC, you define protection pairs. The Cisco MGX 8260 Media Gateway uses 1:N protection for NSCs and 1:1 protection for BSCs. With protection, the system switches to a protection card if an active card fails.

Note The Cisco MGX 8260 Media Gateway Release 1.1 does not support SCC redundancy.

Understanding Physical and Logical Slot Numbers

Cards configured for redundancy may have different physical and logical slot numbers. The physical slot number always represents the physical location of the card in the chassis. The logical slot number is an abstract concept that helps the system keep track of primary and secondary cards.

With 1:1 redundancy, the primary and secondary cards both have the same logical slot number. As such, the system treats them as a single entity for configuration operations. With 1:N redundancy, the secondary card uses logical slot number 0. During switchover, the secondary card assumes the logical number of the card it protects.

Using 1:1 BSC Redundancy

Configure BSC protection using a redundant pair of cards. In order to successfully configure a redundant pair, the following conditions must be true:

When you configure a redundant pair of BSCs, both cards reboot and return to operation with the same logical slot number. The card LED displays green for the active card and yellow for the standby card. A subsequent failure of the active card causes a switchover to the backup card.

During the switchover, the active and standby roles are reversed. The card that failed reboots, and the Card LED changes to either yellow or red, depending on the type of problem. After resolving the failure condition, you restore normal operation by forcing a switchover. The system does not automatically restore the protection pair to its original state.

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.

Adding BSC Redundancy

Warning Adding 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 in the slot adjacent to the one you want to protect.

Step 2 Add a redundant Y cable between all ports on the two cards.

Step 3 On the Navigation pane, click Cards.

Step 4 Click Redundancy Setup.

Step 5 On the Redundancy Setup screen, click the + icon.

The Add Redundant Slot Configuration form opens:


Parameter Description Example

Primary Physical Slot Number

The physical slot for the primary card of the redundancy pair. This slot is active during normal operation.

15

Secondary Physical Slot Number

The physical slot for the secondary card of the redundancy pair. The card in this slot operates in the standby mode during normal operation and protects the primary slot in the event of a primary failure.

16

Step 6 Click Add.

Both cards reboot and initialize for redundancy.

Step 7 Return to the Redundant Slot Configuration screen to verify the configuration.

Deleting Redundancy

To delete redundancy, follow these steps:

Step 1 On the Navigation pane, click Cards.

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; then confirm your action.

The system deletes the redundancy pair and updates the redundancy table.

Forcing a Switchback

After repairing the failure that caused a switchover, you must manually switch the redundancy pair back to the original state.

To force a redundancy switchback, follow these steps:

Step 1 On the Navigation pane, click Card.

Step 2 Click All Cards.

The Logical Card Configuration screen opens.

Step 3 Click the S icon on the row that displays the desired card.

The system forces a switchover with the redundancy pair.

Viewing MSM Configuration

  • failed

Viewing DSP Configuration

To view MSM type and operational status, follow these steps:

Step 1 On the Navigation pane, click DSP-Cards.
