Release Notes for Catalyst 2960L and Catalyst 2960L-Smart Managed Switches, Cisco IOS Release 15.2(6)E2b

Switch Models

Optics Modules

The Catalyst 2960L and Catalyst 2960L-SM 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:

Finding the Software Version and Feature Set

The Cisco IOS image is stored 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 Introduced in Cisco IOS Release 15.2(6)E2b for C2960L-SM Switches

• The Monitoring dashboard gives a snapshot of the switch and its overall general health. The Dashboard view has various dashlets that show the operator important information such as CPU usage, temperature, memory utilization, and power supply status. The event log table shows information about critical system events. The dashboard is refreshed every 60 seconds.
• Ports monitoring enables users to track and monitor port parameters such as description, port status, and type. Details on a specific port in the table can be selected and highlighted by clicking on the port in the logical view at the top.
• The Clients monitoring feature provides detailed information on all the devices connected to the switch in an easy-to-understand tabular format. Known device types are pictorially represented as icons.
• Routing Information Protocol: RIP is a commonly used routing protocol in small to medium TCP/IP networks. It is supported in both IPv4 and IPv6 network environments.
• Supports Spanning Tree Protocol (STP), VLAN Trunking Protocol (VTP), and Bluetooth configuration.
• Supports Layer 2 VLAN with VLAN ID range between 2 and 4094.
• Supports authentication, authorization, and accounting (AAA) configuration using various AAA protocols such as RADIUS, TACACS, and LDAP.
• Supports 802.1X, Mac Authentication Bypass (MAB), and WebAuth access policies.
• Supports access control list (ACL) for actions such as permit and deny to different devices can be applied to multiple interfaces at once. Port-based ACLs for Layer 2 interfaces allow security policies to be applied on individual switch ports.
• Cisco EnergyWise® can be enabled or disabled globally to manage power usage. The end devices connected to the interfaces in the switch can be powered on or off using the Wake on LAN feature.
• Supports SPAN to monitor port traffic. With this feature enabled, switch sends a copy of all the packets seen on one port to another port, where the packets can be analyzed. Bidirectional data support on the SPAN port allows Cisco Intrusion Detection.
• Supports HTTPS and Simple Network Management Protocol (SNMP) v3 based access.
• Allows the user to set the time, specify a config file (import and export), and configure Dynamic Host Configuration Protocol (DHCP). System time can be configured locally, or the switch can be configured to read time from a Network Time Protocol (NTP) server.
• Link Aggregation Control Protocol (LACP) allows the creation of Ethernet channeling with devices that conform to IEEE 802.3ad.

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:

1. Access the BST (use your Cisco user ID and password) at https://tools.cisco.com/bugsearch/.

2. Enter the bug ID in the Search For: field.

Open Caveats
