Release Notes for Catalyst 3560-CX and 2960-CX Series Switches, Cisco IOS Release 15.2(6)E

---

First Published: 08 August, 2017

This release note describes the features and caveats for the Cisco IOS Release 15.2(6)E software on the Catalyst 3560-CX and the Catalyst 2960-CX family of switches.

Verify that these release notes are correct for your switch:

• If you are installing a new switch, see the Cisco IOS release label on the rear panel of the switch.
• If your switch is on, use the show version privileged EXEC command. See the “Upgrading the Switch Software” section.
• If you are upgrading to a new release, see the software upgrade filename for the software version. See the “Software Image” section.

Introduction

The Catalyst 3560-CX and Catalyst 2960-CX switches are compact Gigabit Ethernet (GE) switches that have features comparable to high-end Cisco switches but in smaller form factors. Some of the key features are:

• Up to 10 Gigabit uplinks for high-bandwidth applications and business growth
• Cisco Catalyst Instant Access mode (on 3560cx-12PD-S and 3560CX-8XPD-S switches) for management simplicity on switches with 10G uplink. See Instant Access FAQ here.
• Support for Cisco Application Policy Infrastructure Controller Enterprise Module (APIC-EM) for software-defined networking (SDN) and programmability
• Integration with Cisco TrustSec® for identity, segmentation, and security
• Up to 240W of available power for PoE+ per switch — twice the available power of previous generation switches — for supporting more PoE devices
• Switch Hibernation Mode and Energy Efficient Ethernet (EEE) for lower energy costs
• NetFlow Lite for end-to-end visibility to the flows in the network

Device Manager System Requirements

Upgrading the Switch Software

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.

Features of the Switch

Cisco Catalyst 3560-CX switches features:

• PoE+ and non-PoE, 8 and 12 downlink ports, 1G SFP and 10G SFP+ uplink port models
• IPv4 and IPv6 routing, Multicast routing, advanced quality of service (QoS), and security features in hardware
• Cisco Catalyst Instant Access mode (on WS-C3560CX-12PD-S and WS-C3560CX-8XPD-S switches) for management simplicity on switches with 10G uplink
• Up to 240W of available power for PoE+ per switch
• Switch Hibernation Mode and Energy Efficient Ethernet (EEE) for lower energy costs
• Horizontal Stacking (on WS-C3560CX-12PD-S and WS-C3560CX-8XPD-S switches
• Enhanced Limited Lifetime Warranty (E-LLW) with next business day (NBD) advance hardware replacement and 90 day access to Cisco Technical Assistance Center (TAC) support
• Enhanced Cisco EnergyWise for operational cost optimization by measuring actual power consumption of the PoE devices, reporting, and reducing energy consumption across the network
• USB Type-A and Type-B ports for storage and console respectively
• Application visibility and capacity planning with integrated NetFlow Lite
• Hardware support for Secure Group Access Control lists (SGACL) and IEEE 802.1AE MACsec.
• Software support for IEEE 802.1AE MACsec from Cisco IOS Release 15.2(4)E.

Cisco Catalyst 2960-CX switches features:

• PoE+ and non-PoE models, 8 downlink ports, 1G SFP uplink port models
• Reduced power consumption and advanced energy management features
• USB Type-A and Type-B ports for storage and console respectively
• Application visibility and capacity planning with integrated NetFlow Lite
• Switch Hibernation Mode and Energy Efficient Ethernet (EEE) for lower energy costs
• Enhanced Limited Lifetime Warranty (E-LLW) with next business day (NBD) advance hardware replacement and 90 day access to Cisco Technical Assistance Center (TAC) support
• Enhanced Cisco EnergyWise for operational cost optimization by measuring actual power consumption of the PoE devices, reporting, and reducing energy consumption across the network

New Software Features

• Features Introduced in Cisco IOS Release 15.2(6)E

Service and Support

Limitations and Restrictions

• Starting with Cisco IOS Release 15.2(6)E, Secure Shell (SSH) Version 1 is deprecated. Use SSH Version 2 instead.
• When a logging discriminator is configured and applied to a device, memory leak is seen under heavy syslog or debug output. The rate of the leak is dependent on the quantity of logs produced. In extreme cases, the device may crash. As a workaround, disable the logging discriminator on the device.
• Standalone web-based authentication fails if the switch port is configured without any port ACL. (CSCuu91975)
