Planning Optimum Configurations

This section provides guidelines for planning a configuration with optimum performance. Topics include recommendations for CIP memory, Flash memory cards, and DRAM.

CIP2 Memory Guidelines

Use Table 117 as a simple means to determine a conservative session capacity for the CIP2 DRAM configurations. If a single feature is being deployed with a single session type, use this table. However, if multiple features are deployed concurrently, use the formulas in Table 118.

Table 117 : CIP2 Memory Guidelines

Description	Telnet Sessions	Other TCP Sessions	LLC Sessions
CIP2 with 32-MB DRAM	4,500	450	2,000
CIP2 with 64-MB DRAM1	10,000	950	4,000

¹ A 128-MB DRAM option is also available for the CIP2; MEM-CIP-128M(=).

Table 118 : CIP2 Memory Formulas

Description	Formula
TCP/IP offload feature only	2.5 MB + (6 KB x number of Telnet sessions) + (64 KB x number of other TCP sessions)
CSAN feature only	5.0 MB + (12 KB x number of LLC sessions)
TCP/IP offload and CSAN concurrently	6.5 MB + (6 KB x number of telnet sessions) + (64 KB x number of other TCP sessions) + (12 KB x number of LLC sessions)

For example, if you are configuring the memory for the CSAN feature and you are planning to support 1024 LLC connections, the amount of DRAM required is calculated as follows:

5.0 MB + (12 KB x 1024) = 17 MB

Because the default memory for the CIP2 is 32MB, you will need to order 32 MB of CIP2 DRAM.

If you are configuring the CIP2 for TCP/IP offload and you are planning to support 2048 Telnet sessions and 256 FTP sessions, then the formula is as follows:

2.5 MB + (6 KB x 2048) + (64 KB x 256) = 30.5 MB

This configuration will also require 32 MB of CIP2 DRAM.

Flash Memory Card Guidelines

Use the following guidelines when ordering Flash memory cards:

• Use one card for image storage and another for configurations.
  

• The number of system images that can be stored on the card depends both on the Flash Memory card size and the file size.
  

For complete information about the Cisco 7000 series Flash memory card, see the section "Flash Memory Cards" in the chapter "Cisco 7000 Series." For complete information about the Cisco 7500 series Flash memory card, see the section "Flash Memory Cards" in the chapter "Cisco 7500 Series."

DRAM Guidelines

Use the following guidelines when ordering DRAM for the Cisco 7000 family:

• For the RSP1, RSP2, or RSP7000, DRAM is contained in four SIMM slots (two banks of two SIMMs each).
  

• For the RSP1, RSP2, or RSP7000, Bank 0 must be greater than or equal to Bank 1.
  

• Do not mix DRAM sizes within a bank.
  

Refer to Table 119 for DRAM size recommendations based on the size of your network. Then, consult with your Cisco system engineer to determine the recommended DRAM configuration for your unique network.

Refer to Table 120 for DRAM size requirements for a Cisco 7500 series router running Cisco IOS Release 11.1, and refer to Table 121 for DRAM size requirements for the 7200 NPE running Cisco IOS Release 11.1 or 11.2.

Refer to Table 122 for default SIMM configurations for the RSP1, RSP2 or RSP7000. These factory defaults are designed so that your initial order can be easily upgraded.

Table 119 : DRAM Size Recommendations---RSP1, RSP2, RSP7000,
7200 NPE

Network Size	Cisco 7200	Cisco 7000	Cisco 7010	Cisco 7505	Cisco 7507	Cisco 7513	RSP7000
Small1	16 MB	16 MB	16 MB	16 MB	16 MB	32 MB	16 MB
Medium2	16 MB	16 MB	16 MB	32 MB	32 MB	32 MB	32 MB
Large3	64 MB	64 MB	64 MB	64 MB	64 MB	64 MB	64 MB

¹ Small networks efficiently support <2,000 IProutes.
² Medium networks efficiently support 2,000 to 10,000 IProutes.
³ Large networks efficiently support >10,000 IProutes.

Verifying Interface Processor Compatibility

This section describes how to find out if an existing interface processor is compatible with a Cisco 7500 series router or a Cisco 7000 series router upgraded to include an RSP7000. These procedures are described in the section"Investment Protection Program" in the chapter "Interface Processors for the Cisco 7000 Family."

Process Flowchart

To determine compatibility, use the flowchart in Figure 31 and the compatibility guidelines in Table 123. If you need help in determining a board's part number and revision, see the next section, "Determining Board Part Number and Revision."

¹ A board part number is compatible with Cisco 7500 series or RSP7000 systems if it is equal to or greater than those listed in this column. (See Figure32.)
² The suffix of the part number reflects the fab revision. (See "Cisco Board Numbering Conventions.")
³ It may not be necessary to check the board revision level, because the part number suffix itself may determine compatibility. (See Figure32.)
⁴ A board revision should only be checked if the part number suffix is equal to those listed in the table. In this case, the board revision must be greater than or equal to those listed in the table. (See Figure32.)
⁵ Any interface processors not specifically listed in the table are compatible with Cisco 7500 series or RSP7000.

Figure 32 provides a flowchart to use with Table 123.

Figure 32 : Determining Compatibility from Board Part Numbers and Revision Levels

Cisco Board Numbering Conventions

Cisco uses the following conventions when assigning part numbers and revision levels:

• When a board is released, it ships with the first fab, which is displayed in the part number suffix, and a board revision of A0.
  

Example: 73-0906-01 A0

• When Cisco modifies the board, the revision increments.
  

Example: 73-0906-01 B0, 73-0906-01 C0, 73-0906-01 D0, and so forth.

• When Cisco decides to implement modifications into a fab, the part number suffix increments and the board revision returns to A0.
  

Example: 73-0906-01 M0 changed to 73-0906-02 A0

To illustrate Cisco's board revision conventions, Table 124 follows one board, 73-0906-XX, through several chronological revisions.

73-0906-01 B0	Board is modified.
73-0906-01 C0	Board is again modified.
73-0906-01 D0	Board is again modified.
73-0906-02 A0	Modifications are rolled into a new fabrication.
73-0906-02 B0	Board is modified.
73-0906-02 C0	Board is modified.

Determining Board Part Number and Revision

You can determine the part number and board revision of your interface processor in one of two ways: inspect the physical board or use the show diagbus command online.

The part number and board revision are typically silk-screened along an edge of the interface processor's printed circuit board:

You can also use the show diagbus command to determine the part number and board revision of your interface processor. The following is an example of a compatible CX-EIP6:
