Last Updated: September 02, 2016
This release note gives an overview of the features for the Cisco IOS XE Denali 16.2.x software on the Catalyst 3650 series switch.
Unless otherwise noted, the terms switch and device refer to a standalone switch and to a switch stack.
The Catalyst 3650 switches are the next generation of enterprise class stackable access layer switches that provide full convergence between wired and wireless networks on a single platform. This convergence is built on the resilience of new and improved 160-Gbps StackWise-160. Wired and wireless security and wireless application visibility and control are natively built into the switch.
The Catalyst 3650 switches also support full IEEE 802.3 at Power over Ethernet Plus (PoE+), modular and field replaceable network modules, redundant fans, and power supplies. The Catalyst 3650 switches enhance productivity by enabling applications such as IP telephony, wireless, and video for a true borderless network experience.
Note For Cisco Catalyst 3850 Series Switches and Cisco Catalyst 3650 Series Switches, the Cisco IOS XE Release 3.7E has merged with the Cisco IOS XE Denali 16.1.x. Most features supported on Cisco IOS XE Release 3.7E are also supported on Cisco IOS XE Denali 16.1.x and Cisco IOS XE Denali 16.2.x.
- For information about features not supported in Cisco IOS XE Denali 16.2.x, see Important Notes.
- For information about important software and hardware restrictions and limitations, see Limitations and Restrictions.
- For information about open issues with the software and past opens that are resolved in Cisco IOS XE Denali 16.2.x, see Caveats.
Cisco IOS XE Denali 16.2.x and Cisco IOS XE represent the continuing evolution of the preeminent Cisco IOS operating system. The Cisco IOS XE architecture and well-defined set of APIs extend the Cisco IOS software to improve portability across platforms and extensibility outside the Cisco IOS environment. The Cisco IOS XE software retains the same look and feel of the Cisco IOS software, while providing enhanced future-proofing and improved functionality.
The software image installation process is now optimized:
The installation procedure you have to follow remains the same. See Upgrading the Switch Software |
|
Support for REP, a Cisco proprietary protocol that provides an alternative to Spanning Tree Protocol (STP) to control network loops, handle link failures, and improve convergence time in ring topologies. REP controls a group of ports connected in a segment, ensures that the segment does not create any bridging loops, and responds to link failures within the segment. REP also supports VLAN load balancing. |

The FCC (USA) rule making on 5 GHz released on April 1, 2014 (FCC 14-30 Report and Order) goes into effect for products that are sold or shipped on or after June 2, 2016. Cisco APs and Cisco WLCs will comply with the new rules by supporting the new regulatory domain (– for the US and will create new AP SKUs that are certified under the new rules. Examples of new rules include new 5-GHz band channels permitted for outdoor use, and transmission (Tx) power level increased to 1W for indoor, outdoor, and point-to-point transmissions. Screen capture Note Cisco APs and Cisco WLCs that are in the –A domain category can continue to operate and even coexist with –B domain devices without any issues. We recommend that you upgrade Cisco APs and Cisco WLCs to the appropriate software release that supports –B domain. –B Domain Compliant Cisco APs starting with Cisco IOS XE Denali 16.2.2 are: 3600, 1600, 2600, 3700, 2700, 1700, 702i, 702w, 1552, 1532, 1572. |
The following Catalyst switch models have been introduced:
Provides the ability to automatically create EtherChannels on ports connected to a switch. By default, auto-LAG is disabled globally and is enabled on all port interfaces. Auto-LAG applies to a switch only when it is enabled globally. |
|
Cisco TrustSec (CTS) Security Group Access Control (SGACL) HA |
Support for high availability on switches that support the Cisco StackWise technology. Cisco StackWise provides stateful redundancy and allows the switch stack to enforce and process access control entries. This feature does not require any Cisco TrustSec-specific user configuration. |
Protects data traffic from a failed router or circuit, like Hot Standby Router Protocol (HSRP) and Virtual Router Redundancy Protocol (VRRP), while allowing packet load sharing between a group of redundant routers. See Configuring GLBP. |
|
Support for the new lacp rate command, to set the rate at which LACP packets are sent to LACP-supported interfaces. You can change the timeout rate from 30 seconds (default rate) to 1 second (fast rate). See the lacp rate command. |
|
Option to specify a VLAN name for access and voice VLAN. See the switchport access vlan command. |
|
Rapid PVST+ is now the default spanning-tree mode used on all Ethernet port-based VLANs. |
|
Source Group Tag (SGT) and Destination Group Tag (DGT) over Flexible NetFlow (FNF) |
Support for SGTs and DGTs to be automatically displayed for ingress and egress data, based on the CTS configuration. |
Virtual Router Redundancy Protocol Version 3 (VRRPv3) for IPv4 and IPv6 |
Enables a group of devices to form a single virtual device, to eliminate the single point of failure, which is inherent to a static default routed environment. |
Support for VRF-aware copy commands. You can specify a VRF for copy commands (FTP, TFTP, SCP etc.), when copying files to and from the switch. |
|
Designed to function as wireless QoS, this feature regulates the downlink air-time needed to transmit frames instead of egress bandwidth. The feature allocates air-time autonomously based on the policies implemented. This brings in fairness of time allocated across multiple operators in large deployments. |
|
Provides granular location details of devices (Smartphones, or any Bluetooth-enabled device). This helps push context-sensitive advertising and other information to users. |
|
An ultra-precise location solution that helps you track the location of wireless clients with the accuracy of one meter. This is made possible by the HALO module, an external third radio that attaches to the back of your Cisco Aironet 3600 and 3700 access points. This powerful module combines Wi-Fi and Bluetooth Low Energy (BLE) technologies to allow pinpointing beacons, inventory, and personal mobile devices. Cisco Hyperlocation works in conjunction with Cisco Connected Mobile eXperience (CMX). Combining the Cisco Hyperlocation feature on the Cisco wireless controller with a CMX device help you achieve better location accuracy, which can result in delivering more targeted content to users. When you use CMX with Cisco CleanAir frequency scanning, it is simple to locate failed, lost, and even rogue beacons. See Cisco Hyperlocation. |
|
Pushes wireless configuration and common configuration from the MC to the MAs. This helps you easily configure, monitor, and troubleshoot all the MAs from the MC. See Configuring Mobility. |

Finding the Software Version and Feature Set
Table 6 shows the mapping of the Cisco IOS XE version number and the Cisco IOS version number.
The package files for the Cisco IOS XE software are 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.
This section covers the following scenarios:
Note You cannot use the Web UI to install, upgrade to, or downgrade from Cisco IOS XE Denali 16.1.x and 16.2.1.
Table 8 Changes in Software Installation CLI Commands
When you upgrade from any prior IOS 3.xE release to an IOS XE 16.x release for the first time, the boot loader is automatically upgraded and it will take effect on the next reload. For subsequent IOS XE 16.x releases, if the boot loader is updated in those releases, it will be automatically upgraded when you load the new release on the switch. If you go back to an IOS 3.xE release, your boot loader will not be downgraded. The updated boot loader supports all previous IOS 3.xE releases.
During an IOS image upgrade or downgrade on a PoE or UPoE switch, the microcode is updated to reflect applicable feature enhancements and bug fixes. Do not restart the switch during the upgrade or downgrade process. With the Cisco IOS XE Denali 16.1.1 release, it takes approximately an additional 4 minutes to complete the microcode upgrade in addition to the normal reload time. The microcode update occurs only during an image upgrade or downgrade on PoE or UPoE switches. It does not occur during switch reloads or on non-PoE switches.
The following console messages are displayed during microcode upgrade:
Follow these instructions to upgrade from Cisco IOS XE 3.xE to Cisco IOS XE Denali 16.1.x or 16.2.x in Install Mode:
When you expand the image, if you point to the source image on your TFTP server, you can skip this section and go to Software Install Image to Flash.
Step 1 Make sure your tftp server is reachable from IOS via GigabitEthernet0/0.
Step 2 Copy the image from your tftp server to flash.
Step 3 Use the dir flash command to confirm that the image has been successfully copied to flash.
Step 4 Use the software install command with the ‘new’ and ‘force’ options to expand the target image to flash. You can point to the source image on your TFTP server or in flash if you have it copied to flash.
Note Old files listed in the logs should be removed using the request platform software package clean switch all command, after reload
Step 5 If you said ‘Yes’ to the prompt in software install and your switches are configured with auto boot, the stack will automatically boot up with the new image. If not, you can manually boot flash:packages.conf
Note When you boot the new image, it will automatically update the boot loader.
Step 6 When the new image boots up, you can verify the version of the new image, by checking show version
Step 7 After you have successfully installed the image, you no longer need the.bin image and the file can be deleted from flash of each switch if it was copied to flash.
Follow these instructions to upgrade from Cisco IOS XE 3.xE to Cisco IOS XE Denali 16.1.x or 16.2.x in Bundle Mode:
You cannot boot Cisco IOS XE Denali 16.1.1 via TFTP for the first time with a Cisco IOS XE 3.xE boot loader. The Cisco IOS XE 3.xE boot loaders have a limitation that they cannot boot an image larger than 400MB via the TFTP server. Since Cisco IOS XE Denali 16.1.x is larger than 400MB, you must boot the image via flash.
Note You cannot boot Cisco IOS XE Denali 16.1.1 via TFTP if you have a Cisco IOS XE 3.xE boot loader. The Cisco IOS XE 3.xE boot loaders have a limitation that they cannot boot an image larger than 400MB via TFTP.
Step 1 Make sure your TFTP server is reachable from IOS via GigabitEthernet0/0.
Step 2 Copy the image from your TFTP server to flash.
Note If you have a stack, you must copy the image to the flash of each switch in your stack.

In Cisco IOS XE Denali 16.1.1, right-to-use (RTU) licensing has been modified to allow stack members to join a stack without having the same license level as the rest of the existing stack. The mismatched switch will not be put into Lic-Mismatch state. Even though the switch with the mismatched license is allowed to join the stack, the following syslog message is displayed periodically reminding you to fix the RTU license level:
For more information, see CSCux27336.
The EXEC mode Right to Use License command allows you to activate or deactivate feature set licenses or Adder AP Count Licenses. This command provides options to activate or deactivate any license supported on the platform.
The EXEC mode Right to Use License command has been provided to activate or deactive feature set licenses or Adder AP Count Licenses. This command provides options to activate or deactivate any license supported on the platform.
If the license mismatch switch has a lower license level than other switches in the stack, and the stack is running at IP Services and the mismatch switch is booted with IP Base license.
