Catalyst 4500 Series Switch Cisco IOS Software Release Strategy

This section describes the Catalyst 4500 series switch Cisco IOS release strategy for the Catalyst 4500 series Supervisor Engines II-Plus, Supervisor Engine III, Supervisor Engine IV,

Figure 1 shows the Catalyst 4500 series switch Cisco IOS software release strategy.

Cisco IOS Release 12.1(19)E1 contains only the software and hardware functionality up to and including Cisco IOS Release 12.1(12c)EW1. Subsequent releases on the 12.1 E train, including 12.1(20)E, will be maintenance releases with the Catalyst 4500 feature set in Release 12.1(12c)EW1 feature set. The 12.1 E train is on the General Deployment (GD) track. Cisco IOS software releases are on the 12.1 E train for Catalyst 4500 series switch customers who require the stability of a GD release with a fixed set of features. Cisco IOS releases on the 12.1 E train are not available to Catalyst 4500 series switch Supervisor Engines II-Plus.

Beginning with Release 12.1(13)EW, additional software features and hardware support are introduced in the Cisco IOS 12.1 EW release train for the Catalyst 4500 series switch. Software features such as PBR, DBL, Port Security, and Jumbo Frames, as well as support for the Catalyst 4500 series switch NetFlow Services Card, Supervisor Engine II-Plus, 1000BaseT GBIC, and the AGM module are contained in the 12.1 EW release train. On the 12.1 EW train, the Catalyst 4500 series switch Supervisor Engine II-Plus is supported only in Release 12.1(19)EW and Release 12.1(20)EW. The latest Catalyst 4500 series switch Cisco IOS software release in the 12.1 EW train is Release 12.1(20)EW.

Starting with Release 12.2(18)EW, additional software features and hardware support are introduced in the 12.2 EW release train of Cisco IOS software for the Catalyst 4500 series switch. Software features such as sticky port security, 802.1X accounting, SmartPort macros, as well as support for the Catalyst 4510R chassis, the the IEEE Power over Ethernet (PoE) line cards are contained in the 12.2 EW release train. The Catalyst 4500 series switch Cisco IOS software in the 12.2 EW release train will continue to offer the latest hardware and software features. The 12.2 S mainline releases will be offered in the future to Catalyst 4500 series switch customers for feature consistency across the Catalyst platforms.

Figure 1 Software Release Strategy

Catalyst 4500 Series Switch Cisco IOS Software Release Migration Paths

Cisco IOS Software Release 12.2EW train offers the latest features for the Cisco Catalyst 4500 Series supervisor engines. Customers with Cisco Catalyst 4500 Series supervisor engines who need the latest hardware support and software features should migrate to Cisco IOS Software Release 12.2(25)EWA.

Cisco IOS Software Release 12.2(18)EW1 and all subsequent 12.2(18)EW maintenance releases have only the feature set based on Cisco IOS Software Release 12.2(18)EW for the Cisco Catalyst 4500 Series supervisor engines. Customers with Catalyst 4500 Series supervisor engines who require the stability of a bug fix maintenance release should stay with the Cisco IOS Software Release 12.2(18)EW maintenance releases.

Cisco IOS Software Releases 12.1(19)E1 through 12.1(26)E have only the feature set based on Cisco IOS Software Release 12.1(12c)EW1 for the Cisco Catalyst 4500 Series supervisor engines. Customers with Catalyst 4500 Series supervisor engines who require the stability of a maintenance release should migrate from 12.1E releases to the Cisco IOS Software Release 12.2(18)EW maintenance releases.
