Configuration Tasks for Cards
Resetting a Card
The resetcd command restarts a card and restores its stored configuration. The following table shows
response of the reset command for different card types and operating states:
Warning Resetting a card interrupts service. Perform this operation during light traffic periods or
in a pre-arranged maintenance window.
To reset a card, enter the resetcd command, specifying the card to reset.
The following example resets card 13:
resetcd 13
Understanding Redundancy
The MGX 8260 Media Gateway supports both redundant and non-redundant operation for all cards. The
SCC and DMC don’t require user setup for redundant operation. 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. With protection, the system switches to a protection card if an active card fails.
Understanding Physical and Logical Slot Numbers
Cards configured for redundancy may have logical numbers that are different than physical 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.
