Problem Description

A small number of Cisco 6732 chassis were shipped with partially programmed electrically erasable programmable read-only memory (EEPROM). The Final Systems Test (FST) did not correctly verify the EEPROM programming on the Cisco 6732 chassis. The FST has been upgraded to verify the EEPROM correct programming code.

After changing the default IP address, the customer may not be able to establish a connection with the Cisco 6732 chassis. This issue only affects the IP address of the box for managing traffic. The customer must use the default IP address (192.168.0.2) to provision the unit if the main control card (MCC) is reset. A software upgrade or switching processor causes the MCC to be reset, which leads to the loss of the IP address.

Background

The customer configured the Cisco 6732 chassis IP address for use in their network. The customer was able to communicate to the chassis with the new IP address. The customer then performed a software upgrade. An upgrade requires that the MCC be reset for a new image to take effect. After the reset, the customer could no longer communicate with the Cisco 6732 chassis using the IP address they had set.

Problem Symptoms

At the initial Cisco 6732 chassis power-up, it is necessary to change the default IP address and Subnet Mask to reflect that of the new network address. Once the IP address has been changed, the installer creates a new node (a new IP address), and can access this node using the Element Management System (EMS). In cases where the EEPROM has been partially programmed, the customer loses contact with the Cisco 6732 chassis if they do one of the following three procedures:

  • If one, or both of the MCCs in the chassis are reset.

  • A common control card switch-over is performed.

  • The Cisco 6732 chassis power is cycled.

Note: In these cases, the Cisco 6732 chassis cannot be contacted with the new IP address. The chassis will only respond to the default IP address (192.168.0.2).

To verify that the Cisco 6732 Chassis has an incorrectly programmed EEPROM, do the following:

  1. After powering up the Cisco 6732 chassis, change the default IP address and Subnet Mask to reflect that of the new network.

  2. Create a new node in the EMS NetView with a new IP address.

  3. Access the new node.

  4. Reset both MCC cards in the Cisco 6732 chassis.

  5. Access the new node again.

  6. If access to the new node fails, try to access this node at the default IP address (192.168.0.2). A Sniffer program can also be used to trap the IP address of the Cisco 6732 chassis in place of accessing the node at the default IP address.

Workaround/Solution

If the Cisco 6732 chassis (node) can be accessed with the default IP address, but not with the customer's new IP address, then the Cisco 6732 chassis should be returned to Cisco Systems using the Return Material Authorization (RMA) process.
