Cisco IOS Software Releases 12.2 Special and Early Deployments

Cisco Systems® announces Cisco IOS® Software updates for the Cisco® Catalyst® 3560 Series intelligent Ethernet switches. This new release furthers Cisco leadership in providing secure, reliable, and easily managed LAN switching solutions.

This product bulletin describes the content and delivery information concerning Cisco IOS Software Release 12.2(20)EX. For more information about the Cisco IOS Software release process, see Product Bulletin 537.

The Cisco Catalyst 3560 SFP Interconnect Cable provides for a low-cost, point-to-point, Gigabit Ethernet connection between Catalyst 3560 Series switches. The 50-centimeter (cm) cable is an alternative to using Small Form-Factor Pluggable (SFP) transceivers when interconnecting Catalyst 3560 Series switches through their SFP ports over a short distance. All Cisco Catalyst 3560 Series switches support the SFP Interconnect Cable.

Table 1 shows the features included in Cisco IOS Software Release 12.2(20)EX.

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 preceding links.
