Product Bulletin, No. 1294
OverviewMore than 1300 Cisco Systems customers have purchased the Cisco IOS" Advanced Peer-to-Peer Networking (APPN) feature set called Portable SNA (PSNA) since it was announced in 1995. PSNA will no longer be supported in Cisco IOS Release 12.1 (and later) and has been replaced by a new second-generation Cisco APPN product called SNA Switching Services (SNASw).
Cisco IOS Release 12.0 will reach its End of Sale milestone on August 13, 2001, and its End of Engineering milestone on October 15, 2001. This is the last Cisco IOS release in which the old APPN feature set is supported. Therefore, APPN customers need to migrate to the new SNASw product. To assist customers with this migration, Cisco is offering an upgrade promotion with a 50 percent discount on the SNASw license. This product bulletin provides the upgrade product numbers for this migration.
This promotion is applicable to customers who are running Cisco APPN PSNA in their networks. These customers can replace the old product with SNASw, which eliminates problems inherent with the traditional APPN technology such as extensive broadcast traffic, complex configurations, and poor serviceability, usability, and management. SNASw supports APPN Branch Extender (BX), APPN Enterprise Extender (EE), and Dependent Logical Unit Requester/Dependent Logical Unit Server (DLUR/DLUS) functionality, providing increased reliability, greater scalability, and reduced configuration effort.
Table 1 provides the upgrade product codes for the APPN-to-SNASw migration promotion.
