I recently acquired a Cisco 2960 switch running IOS 12.2 for use in a home lab (in order to prepare for the CCNA exam).
I wanted to configure this router for SSH, but I got an error when I ran the 'crypto key generate rsa' command. Turns out the installed IOS does not support the 'crypto' command.

Cisco ios free download - Apple iOS 13, Cisco Legacy AnyConnect, Cisco VPN Client, and many more programs.
Can someone tell me if I can install IOS 15 on this switch? And if the answer is 'No', what the latest version of IOS that could be installed?
Also, on Cisco's website there seem to be many hundreds of IOS versions. Would like some guidance in finding the correct one.
Below is some selected output when I used the 'show version' command

Introduction
The Catalyst 2960-X and Catalyst 2960-XR switches are Ethernet switches to which you can connect devices such as Cisco IP Phones, Cisco Wireless Access Points, workstations, and other network devices such as servers, routers, and other switches. Some models of the switches support stacking through the Cisco FlexStack-Plus technology. Unless otherwise noted, the term switch refers to both a standalone switch and to a switch stack.

Device Manager System Requirements
Hardware Requirements
DRAM | Resolution | |||
|---|---|---|---|---|
233 MHz minimum6 | 512 MB7 | 256 | 1024 x 768 | Small |
6.We recommend 1 GHz. |
Software Requirements
- Windows 2000, XP, Vista, Windows 7, and Windows Server 2003.
- Internet Explorer 6.0, 7.0, Firefox up to version 27.0 with JavaScript enabled.
Cluster Compatibility
You cannot create and manage switch clusters through Device Manager. To create and manage switch clusters, use the command-line interface (CLI) or the Network Assistant application.
When you create a switch cluster or add a switch to a cluster, follow these guidelines:
- We recommend that you configure the highest-end switch in your cluster as the command switch.
- If you are managing the cluster through Network Assistant, the switch with the latest software should be the command switch.
- The standby command switch must be the same type as the command switch. For example, if the command switch is a Catalyst 2960-X switch, all standby command switches must be Catalyst 2960-X switches.
For additional information about clustering, see Getting Started with Cisco Network Assistant, Release Notes for Cisco Network Assistant, the Cisco-enhanced EtherSwitch service module documentation, the software configuration guide, and the command reference.
CNA Compatibility
For Cisco IOS Release 15.2(2)E, CNA support is available on release version 5.8.9 and later.
You can download Cisco Network Assistant from this URL:

For more information about Cisco Network Assistant, see the Release Notes for Cisco Network Assistant on Cisco.com.
Upgrading the Switch Software
- Before upgrading to Cisco IOS XE Release 3.6.6E, you need to upgrade the Prime Infrastructure software to Release 3.1.4 with Device Pack(DP) 6.
Finding the Software Version and Feature Set
The Cisco IOS image is stored as a bin file in a directory that is named with the Cisco IOS release number. The files necessary for web management are contained in a subdirectory. The image is stored on the system board flash device (flash:).
You can use the show version privileged EXEC command to see the software version that is running on your switch.
Note Although the show version output always shows the software image running on the switch, the model name shown at the end of this display is the factory configuration and does not change if you upgrade the software license.
You can also use the dir filesystem : privileged EXEC command to see the directory names of other software images that you might have stored in flash memory.
Software Image
If you have a service support contract and order a software license or if you order a switch, you receive the universal software image and a specific software license.

Features of the Switch
The Catalyst 2960-X switch supports two different feature sets:
- LAN Lite feature set—Provides standard Layer 2 security, quality of service (QoS), and up to 64 active VLANs. LAN Lite models have reduced functionality and scalability with entry level features in layer 2 and provide no routing capability. They do not support stacking.
- LAN Base feature set—In addition to the LAN Lite feature set, the LAN Base feature set provides more advanced Layer 2 features, extended scalability, routing capability, and support for stacking with FlexStack-Plus. It supports upto 1024 active VLANs.
Specific differences between the two feature sets are described in the following sections.
Ease of Operations
- Cisco Catalyst Smart Operations is a comprehensive set of features that simplify LAN deployment, configuration, and troubleshooting. Catalyst Smart Operations enable zero touch installation and replacement of switches and fast upgrade, as well as ease of troubleshooting with reduced operational cost. Catalyst Smart Operations is a set of features that includes Smart Install, Auto Smartports, Smart Configuration, and Smart Troubleshooting to enhance operational excellence:
– Cisco Smart Install is a transparent plug-and-play technology that can configure the Cisco IOS software image and switch configuration without user intervention. Smart Install uses dynamic IP address allocation and the assistance of other switches to facilitate installation.
– Cisco Auto Smartports provide automatic configuration as devices connect to the switch port, allowing auto detection and plug and play of the device onto the network.
– Cisco Smart Configuration provides a single point of management for a group of switches and in addition adds the ability to archive and back up configuration files to a file server or switch allowing seamless zero touch switch replacement.
– Cisco Smart Troubleshooting is an extensive array of debug diagnostic commands and system health checks within the switch, including Generic Online Diagnostics (GOLD) and Onboard Failure Logging (OBFL).
- NetFlow Lite enables monitoring, capturing, and recording of network traffic for further analysis. NetFlow Lite support is available on the LAN Base image. On the IP Lite image, NetFlow Lite support is available on physical ports configured as either a switch port or a routed port.
- Cisco Prime Infrastructure is a set of tools that enables you to automate much of the management of your Cisco network. It is supported with device pack1 (2.1) 4.
Network Security
The Cisco Catalyst 2960-X Series Switches provide a range of security features to limit access to the network and mitigate threats.
- Port security secures the access to an access or trunk port based on MAC address. It limits the number of learned MAC addresses to deny MAC address flooding.
- DHCP snooping to filter untrusted DHCP messages between untrusted hosts and DHCP servers.
- IP source guard to restrict traffic on nonrouted interfaces by filtering traffic based on the DHCP snooping database and IP source bindings.
- Dynamic ARP inspection (DAI) to prevent malicious attacks on the switch by not relaying invalid ARP requests and responses to other ports in the same VLAN.
- Flexible authentication that supports multiple authentication mechanisms including 802.1X, MAC Authentication Bypass and web authentication using a single, consistent configuration.
- Open mode that creates a user friendly environment for 802.1X operations.
- Comprehensive RADIUS Change of Authorization capability for asynchronous policy management.
- Unicast Reverse Path Forwarding (RPF) feature helps mitigate problems caused by the introduction of malformed or forged (spoofed) IP source addresses into a network by discarding IP packets that lack a verifiable IP source address.
- Cisco security VLAN ACLs on all VLANs prevent unauthorized data flows from being bridged within VLANs.
- Cisco standard and extended IP security router ACLs define security policies on routed interfaces for control-plane and>Headline
