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
- 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)
- Cisco Catalyst Instant Access mode (on Catalyst 3560CX-12PD-S and Catalyst 3560CX-8XPD-S) 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
- Advanced Layer 2 (LAN Base) and Layer 3 (IP Base) support with an option to upgrade to IP services

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.

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.

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)

Cisco Bug Search Tool
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.
To view the details of a caveat listed in this document:
