Memory Guidance for Cisco Catalyst 6500 Series Switches

This bulletin provides guidance on various bootflash and DRAMs to be used in Cisco

Catalyst

6500 Series Switches.

The Cisco Catalyst 6500 has an unparalleled portfolio of features that are mandated by the

growing requirements of our customers for scalability, instrumentation, high availability, and other

factors. As a consequence, in the future, software images might have an increased effect on

memory requirements. Additionally, as the size of Internet routing tables continue to increase, the

quantity of routes in enterprise networks will also grow.

The Cisco Catalyst 6500 Series released its latest software image, Cisco IOS

Software Release

12.2(33)SXH, with more than 200 features to cater to different areas of the network such as Data

Center, Campus Backbone, Wiring Closet, Enterprise WAN, and Carrier Ethernet. With this

software introduction, current default configurations, with the exception of XL configurations, are

designed to hold typical enterprise configurations. Typical enterprise configurations are defined as

having 25,000 route entries and 4000 access control list (ACL) entries. Table 1 lists upgrade

options for various modules with considerations for Bootflash/Compact Flash (Bootdisk)/DRAM

upgrade

This does NOT affect the Compact Flash purchase for the supervisor engine’s external slot. We

suggest that the Compact Flash size for the external slot be at least equivalent to the

recommended size for respective supervisor engines.

Figure 1 shows bootflash/Compact Flash (Bootdisk) and DRAM locations on the Cisco Virtual

Switching Supervisor Engine 720 with 10 Gigabit Ethernet Uplinks. For details about individual

supervisor engines, see
