An MS-DOS formatted ATA Flash PC card or linear Flash PC card can be accessed successfully (including the dir command) with the Catalyst and Cisco IOS operating systems but will not boot from

ROMMON.

The 16-MB MEM-C6K-FLC16M and 24-MB MEM-C6K-FLC24M linear Flash PC cards are formatted for the Catalyst 6500 series supervisor engines and are ready to use.

The MEM-C6K-ATA-1-64M and 64-MB MEM-C6K-FLC64M Flash PC cards are not formatted. You must format these cards (see Table 1 on page 7 for a description of the format command.) When you enter the dir disk0: or dir slot0: commands, an unformatted Flash PC card returns a “bad device block info” or “invalid magic number” error message.

Supervisor Engine 1 and Supervisor Engine 2 do not support the same Flash PC card format. To use a Flash PC card with Supervisor Engine 2, you must format the card with Supervisor Engine 2. To use a Flash PC card with Supervisor Engine 1, you must format the card with Supervisor Engine 1.

Table 1 Table 1Table 1Table 1shows many of the commands that are available for using and managing Flash devices, including the Flash PC cards. To perform specific tasks, use these commands either alone or combined with other commands. For example, to copy a file from a TFTP server to a Flash PC card, set the BOOT environment variable so that the system will boot from this new image and then verify the boot sequence as shown in the following steps:

The following commands listed in Table 1 are not applicable to the ATA Flash (disk0:) PC card: undelete, squeeze, show flash devices, show flash, and verify.

The ATA Flash PC card is accessed through disk0: and the 16-MB, 24-MB, and 64-MB Flash PC cards are accessed through slot0:. The following procedure uses slot0:.

Step 1 Copy a file from a TFTP server to the Flash PC card in slot0:

Console (enable) copy tftp slot0:

Step 2 Set the BOOT environment variable so that the system boots from slot0:

Console (enable) set boot system flash slot0:cat6000-sup-5-1-1-CSX.bin prepend

Step 3 Display the contents of the BOOT environment variable:

Console (enable) show boot

For complete descriptions of these commands and how to use them, refer to the Catalyst 6500 Series Software Configuration Guide and the Catalyst 6500 Series Command Reference publication.

Cisco Systems is a leading provider of networking solutions, and their Memory modules play a crucial role in enhancing the performance of their Catalyst series switches. Among these modules are the MEM-C6K-FLC64M, MEM-C6K-ATA-1-64M, MEM-C6K-FLC24M, and MEM-C6K-FLC16M. These memory upgrades are integral to ensuring that Cisco's hardware can meet the demands of modern networking environments.

The MEM-C6K-FLC64M is a 64MB DRAM memory upgrade designed for Cisco's Catalyst 6500 series switches. This module provides the necessary bandwidth to support higher packet processing capabilities. It enhances system performance by increasing the memory available for routing tables, ACLs, and IP routing. With this upgrade, users experience reduced latency and improved data throughput, making it ideal for high-demand environments.

The MEM-C6K-ATA-1-64M is a 64MB ATA flash memory card tailored for the Catalyst 6500 series. This flash memory provides substantial storage for operating system images, configuration files, and other essential data. Its reliability ensures that critical information is readily accessible, allowing for quicker boot times and seamless upgrades. The durability of flash storage further enhances the system's resilience against failures.

On the other hand, the MEM-C6K-FLC24M is a 24MB DRAM upgrade. While it offers less capacity than the MEM-C6K-FLC64M, it is a cost-effective solution for those not requiring extensive memory enhancements. It is particularly suitable for deployments where basic memory expansion suffices for operational efficiency without breaking the bank.

Lastly, the MEM-C6K-FLC16M provides a 16MB expansion option. Although it is the smallest capacity in this lineup, it remains significant for environments where minimal memory increases are needed. This module can still offer a performance boost, especially in smaller networks or in situations where budget constraints are a primary concern.

In summary, the MEM-C6K-FLC64M, MEM-C6K-ATA-1-64M, MEM-C6K-FLC24M, and MEM-C6K-FLC16M are essential components in optimizing the capabilities of Cisco's Catalyst 6500 switches. They allow network operators to tailor the memory resources of their systems according to their specific performance requirements, ensuring that they can manage network traffic efficiently and reliably. The diverse options available enable flexibility and scalability to meet the evolving needs of modern enterprise networks.
