CUSTOMER IMPACT

This news will have the greatest impact on customers who have settled upon 11.3AA maintenance releases as their “standard” router network

software. Important issues to note follow:

1. Customer Engineering (CE) will still answer technical questions regarding Cisco IOS Software Release 11.3AA.

2. To utilize an obsolete release on hardware platforms ordered in the future, customers may maintain the software on a TFTP server at their site

and utilize netboot procedures. In most instances, this should not be a major issue since most customers likely keep software backups at their

site in order to have a quick retrieval mechanism in case of emergency.

3. The migration path for customers on all platforms who are currently on 11.3AA is 12.0 or 12.0T.

4. Customers needing memory upgrades for the following platforms will be handled on a case-by-case basis:

–

3640: No change in minimum memory requirements.

–

5200: Desktop and Desktop Plus images required 8 MB Flash in 11.3AA; both will require 16 MB Flash in 12.0 and 12.0T.

–

5300: No change in minimum memory requirements.

–

5800: No change in minimum memory requirements.

–

7200: No change in minimum memory requirements.

Nonetheless, please explicitly discuss this issue with your customers utilizing older software releases and ensure that they have the software on

site.
