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 2960L and Catalyst 2960L-SM 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.
Supported Hardware
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:
http://www.cisco.com/c/en/us/td/docs/interfaces_modules/transceiver_modules/compatibility/matrix/GE_Tx_Matrix.html
Device Manager System Requirements
The following table lists the system requirements for a PC running Cisco Configuration Professional for Catalyst (CPC), including Web browser versions.
Upgrading the Switch Software
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.
Limitations and Restrictions
- There is limit of 384 ACEs for MAC/IPv4 and 256 ACEs for IPv6. For some scenarios, one ACE entry can lead to 2 TCAM entries. For IPv6, 512 TCAM entries are used per ASIC.
- Extension header match options for IPv6 PACLs are not supported on the switch. Also, PACLs not supported in the out direction.
- Storm control for multicast with PPS and % may not work.
New Software Features
Features Introduced in Cisco IOS Release 15.2(7)E for C2960L-SM Switches
- Improvements to Link Aggregation Control Protocol (LACP) configuration on ports and device using priority settings.
- Along with IPv4, you can now configure through IPv6 address; with support for IPv6 static routing.
- Support for VTP pruning to eliminate or prune unnecessary traffic.
- Enhancements to STP with added fields for Forward Time, Hello Time, Max Age, Transmit Hold-Count, STP Port Types, Edge-BPDU Filter, Edge-BPDU Guard and STP Loopguard.
