Software Image Upgrade Path
Figure 1 displays Cisco IOS Software Release 12.2(58)EX functions for Releases 12.2S and 12.2SE and identifies the recommended migration path.
Because of export restrictions on strong cryptography software, a separate image is required for the cryptographic features (Secure Shell [SSH] Protocol, Simple Network Management Protocol Version 3 [SNMPv3], and Kerberos Protocol). These software images can be downloaded from the corresponding Triple Data Encryption Standard (3DES) area of the links provided in this section. Note that the Cisco Advanced IP Services license is available only in cryptographic format.
