Associated Feature Image and Memory Updates

Addition of New "Basic" Images for Cisco 261x (non XM), Cisco 262x (non XM) and Cisco 3620 Routers, With Revised Memory Recommendations Starting in 12.2(13)T

As more functionality is added to the current mix of Cisco platforms, additional memory requirements are needed to run these images. This has affected some platforms such as the Cisco 261x, Cisco 262x and Cisco 3620, since these platforms only support a maximum of 64MB of DRAM and/or a maximum of 16MB of Flash (Cisco 261x only). In order to address these platforms with limited memory capacity and provide a migration through 12.3 mainline, a number of "Basic" images listed in Table 1 below have been created to address this need. Due to these memory constraints, these platforms will not be supported in IOS 12.3T and beyond. These new images are based on a reduced feature set and/or do not include new functionality in the same release as other new non "Basic" images. Please refer to product price list for further information or contact your Cisco Account Manager.

The Cisco IOS images in Table 1 below represent the recommended minimum memory requirements for use with the Cisco 2600 and Cisco 3620 models. These recommendations are for the current 12.2(13)T release and future 12.2T Releases thereafter. Some Cisco IOS feature sets will exceed the maximum limitations of the current Cisco 2600 or Cisco 3620 platforms. Those IOS feature sets will no longer be orderable for those platforms. For recommendations on a migration to other similar IOS images, refer to the section on "Addition of New "Basic" Images for Cisco 261x (non XM), Cisco 262x (non XM) and Cisco 3620 routers" and information outlined in Table 2.

[1] These Basic images are provided for the Cisco 2610, 2611, 2612 & 2613 models only since the maximum flash supported for these models is 16MB. The Cisco 2620 and 2621 can support 32MB of Flash and 64MB of DRAM on the IP Plus image.

Recommended Migration Path for 12.2T images no longer supported on the Cisco 261x, Cisco 262x and Cisco 3620

The following table provides a migration path for images that require more than 64MB of DRAM support on the Cisco 261x, Cisco 262x and Cisco 3620 models. These "Basic" images are provided for a migration path through 12.3 mainline. The "Basic" images referenced will be supported in 12.2T and 12.3 mainline only.

* Includes AC, DC and RPS versions

DECNet phase IV removal from Desktop Features and migration to Enterprise Plus & Enterprise Basic in 12.2(13)T on the Cisco 2600 and Cisco 3600 Series Routers

DECNet IV Removal from Desktop Features:

The images listed in Table 4 are no longer offered starting in 12.2(2)XT, 12.2(8)T and beyond. In place of these current feature sets, new feature sets listed in Table 5 will be offered. These feature sets offer the same functionality as those in Table 4 with the exception of DECNet Phase IV, which has been removed. These new features are deferred in 12.2(8)T, but are offered starting with 12.2(11)T and 12.2(13)T (Basic image) with the Cisco 2600, Cisco 3640, Cisco 3660 and Cisco 3700 Platforms. The exception is the Cisco 3620, which has the current Desktop features deferred. A subset of the Desktop features in Table 5 for the Cisco 3620 is planned for the 6th Release of 12.2T, but will not include DECNet Phase IV or Appletalk. (Refer to Section 5.0 for more information on the Cisco 3620). For customer requiring DECNet phase IV support on all Cisco 2600 or Cisco 3600 Series routers past 12.2(4)T, refer to Section 4.2

Note: Note: These images listed in Table 5 were deferred in 12.2(8)T and were not offered until 12.2(11)T, including 12.2(13)T for the Basic image. Images listed in Table 5 for the Cisco 3620 are deferred starting in 12.2(8)T with a limited Desktop feature subset without the support of Appletalk or DECNet Phase IV.

Note: AppleTalk is no longer available for the 3620 in any IOS feature set beginning with IOS 12.2(8)T.

Addition of DECNet in Enterprise Plus Images and Enterprise Basic in 12.2(13)T:

DECNet Phase IV was removed from all feature sets in 12.2(2)XT, 12.2(8)T, and 12.2(11)T for the 2600 Series, 2600XM Series, and 3600 Series. DECNet IV is reintroduced in Enterprise Plus and Enterprise Basicimages starting with release 12.2(13)T on the Cisco 2600 (excludes Cisco 2691) and Cisco 3600 (excludes Cisco 3631). DecNet Phase IV support is introduced on the Cisco 2691 and Cisco 3700 Series beginning with IOS release 12.2(15)T.

AppleTalk Removed and Deferral of IP/IPX Desktop images on the Cisco 3620

The Cisco 3620 memory capacity is 32MB of Flash and 64MB of DRAM. This memory capacity limits a number of 12.2(13)T images that require more than 64MB of DRAM on the Cisco 3620. In order to provide support through 12.3 mainline on a number of current and "Basic" images, support for AppleTalk has been removed on the Cisco 3620 due to declining demand for this legacy service. This does not affect the Cisco 2600, Cisco 3640, Cisco 3660 or Cisco 3700 models. The IP/IPX/AppleTalk feature images are deferred on the Cisco 3620 starting in 12.2(8)T and new IP/IPX feature sets are available in 12.2(15)T. These new feature sets will not include support for DECNet or AppleTalk.

For those customers requiring Appletalk, the recommended future migration path is the Cisco 2691 or Cisco 3725. The Cisco 3725 offers more than twice the performance, higher density for service intensive applications and provides AppleTalk and Decnet Phase IV support for images outlined in Table 5. Also, additional trade-in credits are being offered through the Cisco Technology Migration program (CTMP) for trade-ins of Cisco 3620 to Cisco 3725s. This additional credit has been increased by 50% against the normal trade-in credit received. This additional credit has been extended through April 2003.

High Density Analog and Fax Network Module Not Supported on the Cisco 3620

The High Density Analog and Fax Network Module (NM-HDA) is not supported on the Cisco 3620, but is supported on the Cisco 2600 Series, Cisco 3640, Cisco 3660 and Cisco 3700 Series.

Images No Longer Orderable on Cisco 261x, 262x (Non XM models) and 3620 models starting with 12.2T

Cisco 2610, 2611, 2612, 2613, 2620, 2621 Non-XM Routers

The maximum memory capacity of the Cisco 261x and Cisco 262x non-XM routers are 16MB Flash (Cisco 261x), 32MB Flash (Cisco 262x) and 64MB of DRAM. The images in Table 7 and 8, exceed the DRAM capacity or the Flash capacity. The IOS feature sets listed below can no longer be ordered on the Cisco 261x and Cisco 262x with Cisco IOS Releases from 12.2T or higher future releases. See Table 2 for the recommended IOS migration path or migrate to the Cisco 2600XM models. This does not include any of the Cisco 265x, 2600XM or 2691 models.

Cisco 3620 Router

The maximum memory capacity of the Cisco 3620 router is 32MB Flash and 64MB of DRAM. The images in Table 9 below exceed the DRAM capacity and these images are deferred in Cisco IOS Release 12.2(2)XT and all Cisco IOS 12.2T releases, and beyond. These IOS feature sets can no longer be ordered on the Cisco 3620 with Cisco IOS Releases 12.2(2)XT, 12.2T, or any future releases of these feature sets. The recommended migration path for these images is listed in Table 2.
