Figure 3 shows the eight different packages that are available. With IOS Version 12.3 though 15, this has remained relatively constant. The way that Cisco has named their IOS packages has changed over time. For IOS Version15, some of those currently available are Version 15X (special or early deployment), 15S (7600), 15Y (Sup-2T-10GE РІР‚вЂњ Catalyst 6500), 15SG (Sup-CS-S2T РІР‚вЂњ Catalyst 6500), and 15SE (2960, 3560, 3650, and 3750 platforms). 15X, 15S, 15SY, 15SG, 15SEР”Р„s with IOS Version 12, IOS Version 15 is going to have a number of different versions that are specific to new equipment that needs to support new features (specific to the platform). After 15T releases have been tested thoroughly, they are wrapped into the next 15M release. 15TР”Р„s with IOS version 12T, version 15T is focused on new features and platforms and is supported for a shorter amount of time than the maintenance releases. IOS Version 15 has a notation that is similar to IOS Version 12 and is shown in Figure 2.Р”Р‡igure 2 IOS Version 15 Version Notation 15MР”Р„s with IOS version 12, IOS Version 15M provides a mainline release and is also referred to as a maintenance release. The way that different versions are referenced with IOS Version 15 is similar to that of IOS Version 12.

The ones shown in the section name are an incomplete list but do show some of the common examples.

Many different IOS versions provide support for specific platforms.

After the software has been tested thoroughly, it is rolled into the mainline release. The T train is used to add the newest features and platforms. (They go through the release process shown in the previous section.) 12T

Other more specialized versions of IOS are rolled into the mainline as an update when they have been sufficiently tested. These releases tend to be the most stable and include support for most of the available platforms. The 12 base versions are also referred to as the mainline release of a version. IOS Version 12 has a few different ways to notate version, including those shown in Figure 1.Р”Р‡igure 1 IOS Version 12 Version Notation 12 With IOS Version 12, many different sub-versions of IOS exist, including specialized support for specific platforms the next few sections cover a couple of the most common. This article takes a look at a few of these and how what they are used for. IOS VersionsР”Р„ number of different versions exist within each release of IOS. MD releases (called M releases, or extended release) will be released and have a 44-month support window, whereas ED (T releases, or standard release) will have a 18-month support window.

With IOS 15 and later, the code bases will be consolidated. With earlier versions of IOS, the different ED (T trains for instance, 12.4T) and MD (not T trains for instance, 12.4) has different code bases. The IOS train paths have also been consolidated. New releases will be considered either ED or MD. With IOS 15 and later, both the LD and GD deployments will be retired. Maintenance Deployment (MD): These releases are used to provide additional support for bug fixes and ongoing software maintenance. These tend to be stable on almost all platforms. General Deployment (GD): These releases can be used anywhere in a customer network with the same feature and functionality requirements. LD releases are between an ED release and a GD release. Limited Deployment (LD): These releases do not include any new features or platform support but do include bug fixes. With versions of IOS earlier than 15, a specific image could be considered one of the following four different release types:Р”В®arly Deployment (ED): These releases provide both new features and new platform support in addition to bug fixes. One term that is often used is the IOS release type. Although this is not an exhaustive list of every Cisco version, it does cover the most commonly used versions. This article covers these different releases and aims to give a single location where network engineers can look to figure out what the different releases mean. Although the naming used for some of the newer devices is changing to a simpler structure, it will be a while before all the different versions are consolidated. One thing that is often confusing to any network engineer (regardless of level) is the version and naming structure used by Cisco for their IOS images.
