Release Notes for Catalyst 3560-CX and 2960-CX Series Switches, Cisco IOS Release 15.2(3)E and Later
First Published: 10 December, 2015
Last Updated: 15 January, 2016
This release note describes the features and caveats for the Cisco IOS Release 15.2(3)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.
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
6 Gigabit Ethernet plus 2 Multigigabit Ethernet (100 Mbps/1/2.5/5/10 Gbps) ports with line rate forwarding performance (Catalyst 3560CX-8XPD-S)
(IP Base) Commands under global parameter-map to enable non SVI and VRF aware Web-auth configuration.
Rapid PVST+
(All licenses) Rapid PVST+ is now the default spanning-tree mode used on all Ethernet port-based VLANs
Enhancement to Smart Install
(All licenses) PnP discovery process via various discovery mechanisms and security methods is supported
Named VLAN
(All licenses) Option to specify a VLAN name for access and voice VLAN.
What’s New in Cisco IOS Release 15.2(3)E2
There are no new features to mention here.
What’s New in Cisco IOS Release 15.2(3)E1
Software
Cisco Discovery Protocol Bypass—In Cisco Discovery Protocol Bypass mode Cisco Discovery Protocol packets are received and transmitted unchanged. Received packets are not processed. No packets are generated.
The Cisco Discovery Protocol Bypass feature support is available in Cisco IOS Release 15.2(3)E1 and later releases. This feature support was discontinued in Cisco IOS Release15.2(1)E.
New Hardware Support
Catalyst 3560CX-8XPD-S switch that supports SFP+ module slots and Catalyst 3560CX-8PT-S switch that provides support for Cisco Universal PoE (Cisco UPOE™). For more details about these switches, see the Switch Models section.
Optional auxiliary AC-DC or DC-DC power adapter for powering up the Catalyst 3560CX-8PT-S switches.
Optional power adapter bracket to secure the auxiliary power adapter.
Cisco Multigigabit Ethernet
Cisco’s Multigigabit Ethernet technology allows you to leverage 802.11ac Wave 2 speeds on your device. You can configure the WS-C3560CX-8XPD-S module to auto-negotiate multiple speeds on switch ports, and support 100 Mbps, 1 Gbps, 2.5 Gbps, and 5 Gbps speeds on Category 5e cables, and up to 10 Gbps over Category6 and Category 6A cables.
The WS-C3560CX-8XPD-S module has 8 ports, of which the 6 ports are 1 Gigabit Ethernet ports and 2 ports are Multigigabit ports.
PoE pass-through
The Cisco Catalyst 3560CX-8PT-S has eight downlink ports with two Cisco UPOE input ports that allows it to be powered by another switch. These switches receive power over the uplink from an upstream PoE or Cisco UPOE device.The switch can also receive power from an AC power source when you use the auxiliary power input.

Optics Modules
The Catalyst 3560-CX and 2960-CX switches support a wide range of optics. Because the list of supported optics is updated on a regular basis, consult the tables at this URL for the latest SFP+ and SFP module compatibility information:

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.
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.

Limitations and Restrictions
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)
The Bug Search Tool (BST), which is the online successor to Bug Toolkit, is designed to improve the effectiveness in network risk management and device troubleshooting. The BST allows partners and customers to search for software bugs based on product, release, and keyword, and aggregates key data such as bug details, product, and version. The tool has a provision to filter bugs based on credentials to provide external and internal bug views for the search input.
