---

March 4, 2008

---

Note•This publication applies to these platforms:

–CAT6000-SUP2/MSFC2

–7600-SUP2/MSFC2

–CAT6000-SUP1/MSFC2 (not supported in Release 12.2(27b)E2 and later releases)

–CAT6000-SUP1/MSFC1 (not supported in Release 12.2(27b)E2 and later releases)

•This publication is for Cisco IOS Release 12.1E on both the supervisor engine and the MSFC. If you are running the Catalyst operating system on the supervisor engine and Cisco IOS software only on the MSFC, refer to the Release Notes for MSFC publication:

http://www.cisco.com/en/US/docs/switches/lan/catalyst6500/ios/12.1E/hybrid/release/notes/OL_2309.html

---

In these release notes, the term "MSFC" refers to either an MSFC2 or an MSFC1, except when specifically differentiated.

The term "Catalyst 6500 series switches" includes both Catalyst 6500 series and Catalyst 6000 series switches except where specifically differentiated.

The most current release notes for 12.1E on the Catalyst 6500 series switches and Cisco 7600 Series Routers are available on Cisco.com:

http://www.cisco.com/en/US/docs/switches/lan/catalyst6500/ios/12.1E/native/release/notes/OL_2310.html

---

Caution Cisco IOS running on the supervisor engine and the MSFC supports redundant configurations where the supervisor engines and MSFC routers are identical. If they are not identical, one will boot first and become active and hold the other supervisor engine and MSFC in a reset condition.

Early Deployment Releases

Release 12.1E supports the Catalyst 6500 series switches and Cisco 7600 series routers.

Release 12.1E is an early deployment release based on Release 12.1. All features and functionality in Release 12.1(26) and earlier 12.1E releases are in Release 12.1(26)E6.

For information on earlier releases, refer to these publications on Cisco.com:

http://www.cisco.com/en/US/products/hw/switches/ps708/prod_release_notes_list.html

For more information about the Cisco IOS software release process, refer to the Cisco IOS Software Releases: Product Bulletin #537 on Cisco.com at this URL:

http://www.cisco.com/warp/public/cc/pd/iosw/iore/prodlit/537_pp.htm

This publication does not describe features that are available in Release 12.1, Release 12.1 T, or other Release 12.1 early deployment releases.

All caveats resolved in Release 12.1(26) and earlier 12.1E releases are also resolved in Release 12.1(26)E6. For a list of the open caveats that apply to Release 12.1(26)E6, see the "Caveats" section and refer to the Caveats for Cisco IOS Release 12.1 publication:

http://www.cisco.com/en/US/docs/ios/12_1/relnotes/crossplatform/release/notes/121mcavs.html

Memory Requirements and Recommendations

These sections describe memory requirements:

•Supervisor Engine 2, PFC2, and MSFC2 Default and Recommended Configurations

•Supervisor Engine 2, PFC2, DFCs, and MSFC2 with EIGRP or OSPF

•Supervisor Engine 2, PFC2, DFCs, and MSFC2 with BGP

•Supervisor Engine 2 and MSFC2 Upgrades

•Supervisor Engine 1, PFC, MSFC, and MSFC2 Default and Recommended Configurations

Supervisor Engine 2, PFC2, and MSFC2 Default and Recommended Configurations

Supervisor Engine Part Number		Default Configuration		Recommendations
		DRAM	Bootflash	DRAM	Bootflash
WS-X6K-S2U-MSFC2:
	MSFC2	256 MB	321 MB	256 MB	321 MB
	Supervisor Engine 2	256 MB	32 MB	256 MB	32 MB
WS-X6K-S2-MSFC2:
	MSFC2	128 MB2	321 MB	256 MB	321 MB
	Supervisor Engine 2	128 MB2	32 MB3	128 MB	32 MB

1 The bootflash size might be 16 MB. Enter the show version command to display the "Flash internal SIMM" size. You cannot boot a supervisor engine image stored in the MSFC2 bootflash. 2 For large networks or complex configurations, we recommend upgrading the memory on the MSFC2 prior to loading 12.1(8a)E or later (see the "Supervisor Engine 2 and MSFC2 Upgrades" section). 3 The sup-bootflash size might be 16 MB. A 16-MB bootflash device is not large enough to store the supervisor engine image on the supervisor engine bootflash. Enter the remote command switch show version command to display the "Flash internal SIMM" size and upgrade if necessary.

Note Install more memory if your configuration exceeds the limits shown.

Supervisor Engine 2, PFC2, DFCs, and MSFC2 with BGP

Memory Configuration	Maximum Number of BGP Routes per CEF Path
	Variable Length Subnet Masking	Fixed Length Subnet Masking
MSFC2 with 512 MB, Supervisor Engine 2 with 512 MB, DFC with 256 MB	150,000 routes	250,000 routes
MSFC2 with 256 MB, Supervisor Engine 2 with 256 MB, DFC with 128 MB	64,000 routes	150,000 routes
MSFC2 with 128 MB, Supervisor Engine 2 with 128 MB, DFC with 128 MB	32,000 routes	50,000 routes
Note Install more memory if your configuration exceeds the limits shown.
