Configuration Tasks for Cards
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 7 or 8. Enter the following
command to verify the hardware:
lscds
Step 2 Verify that the redundant NSC does not have a redundancy back card installed. See “Viewing Summary
Information for Cards” section on page 3-7.
Step 3 Verify that each primary NSC does not have a back card installed.
Step 4 Add a redundancy pair using the addreds command.
Step 5 Repeat the previous step to assign additional primary slots to the designated secondary slot. Each
MGX 8260 chassis can have only one secondary slot for NSC cards.
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 BSC 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 any available slot from 11 to 16.
Step 2 Add a redundant “Y” cable between all ports on the two cards.
Step 3 From a management session, add a redundancy pair using the addreds command.
Both cards reboot and return to operation with the same logical slot number.
Deleting Redundancy
To delete a redundancy pair, enter the delreds command specifying the primary and secondary slots.
The following example deletes the redundancy pair where slot 1 is primary and slot 3 is secondary:
delreds 1 3
The redundant card continues to protect other primary cards with which it is paired.
