Real World Application This lab will help you will identify the Cisco Internetwork Operating System (Cisco IOS) Running on a Cisco Device. Knowing what Cisco IOS Version and Feature Set is running on your Cisco devices is crucial to planning and deploying required features. Think of Feature Sets as Windows Vista Distributions, you have Basic, Home Edition, Home Premium, Business, Ultimate and Enterprise. Golden Software Grapher 11 Serial more.

Is is possible to simulate a Cisco 3750 switch of do I need to work with the default ethernet switch provided by GNS3? (I have the IOS).
In Cisco IOS, we have similar distributions called “Feature Sets” that dictate which features will be available for you to configure. Each feature set have different prices. Some feature sets contain the same features as others; this will be discussed later in the lab. Lab Prerequisites • Complete Lab 1.2 before attempting this lab or have a current Cisco console session open to your Cisco device.
Lab Objectives • Identify what IOS Version and Features Set your Cisco device is currently running. Lab Instruction There are several ways to identify which Cisco IOS your Cisco device is running. First way being to examine the boot dispatch, this will display the image name that is loaded from flash which in return can be used to identify the IOS Version and Feature Set of the image.
Provided below is an example of the required dispatch from the boot process which can be used to identify which IOS Version and Feature Sets the router is currently loading. Cisco Internetwork Operating System Software IOS (tm) 3600 Software (C3620-IK9O3S7-M), Version 12.3(25), RELEASE SOFTWARE (fc1) Turn your attention to line 2 where you see C3620-IK9O3S7-M; this displays the features that are included in the image and the loading type (which will be discussed later) for the image that is currently be loaded by the Router. Following the feature set being loaded you can also see the Version of the IOS.
As shown in this example, the router is currently booting IOS Version 12.3(25) The most common way of obtaining IOS identification information is by using the show version command. This command shows various information pertaining to the Cisco IOS Version and Feature Set as well as hardware information about the router.
The textbox below shows the dispatch of the show version command.

Processor board ID 24807256 R4700 CPU at 80MHz, Implementation 33, Rev 1.0 Bridging software. X.25 software, Version 3.0.0. 2 FastEthernet/IEEE 802.3 interface(s) 32 terminal line(s) DRAM configuration is 32 bits wide with parity disabled. 29K bytes of non-volatile configuration memory.
32768K bytes of processor board System flash (Read/Write) Configuration register is 0x2102 Router# As you can see lines 2, 3 & 4 are identical to previously discussed boot dispatch information. However take look at line 13 and you’ll see System image file is “flash:c3620-ik9o3s7-mz.123-25.bin” This is the actual image file name that is currently running on the router. This image name is very helpful in identifying the IOS Version and Feature set. Prior to Cisco IOS Version 12.4, Cisco had a very complex naming convention for their Feature Sets.
This naming convention consisted of letters identifying certain features in the image.
