Introduction
Cisco Catalyst 3650 Series 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.
Cisco Catalyst 3650 Series Switches also support full IEEE 802.3at Power over Ethernet Plus (PoE+), modular and field replaceable network modules, redundant fans, and power supplies. The Cisco Catalyst 3650 Series Switches enhance productivity by enabling applications such as IP telephony, wireless, and video for a true borderless network experience.
Cisco IOS XE Denali 16.x.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.

(IP Base and IP Services)
XOR Radio Resource Management (RRM)
In Cisco Aironet 2800/3800 series access points, slot 0 is an XOR (Dual-Band) radio that offers the ability to serve either 2.4- or 5-GHz band, or passively monitor both bands on the same radio.
100BASE-FX SFP module for Gigabit Ethernet ports, 1310 nm wavelength, 2 km over MMF
The Cisco Catalyst 3650 Series Switches now support the GLC-GE-100FX SFP transceiver module on 8 X10 Gigabit Ethernet fixed uplink ports, on these switch models:
Describes the role that security group-based access control lists (SGACLs) play in a Cisco TrustSec solution, to enforce role-based access control, identity-aware networking, and data confidentiality—thus securing the network and its resources.
Refers to standard IEEE 802.1 BA - AVB. This feature defines a mechanism whereby endpoints and the network function as a whole to enable high-quality streaming of professional audio and video (AV) over an Ethernet infrastructure. Instead of one-to-one, the network transport enables many-to-many seamless plug-n-play connections for multiple AV endpoints including talkers and listeners.
AVB is composed of the following:
Generalized Precision Time Protocol (gPTP)—IEEE 802.1AS. Provides a mechanism to synchronize clocks of the bridges and end point devices in an AVB network.
Quality of Service (QoS)—IEEE 802.1Qav. Guarantees bandwidth and minimum bounded latency for the time-sensitive audio and video streams.
Multiple Stream Reservation Protocol (MSRP)—IEEE 802.1Qat. Provides a mechanism for end stations to reserve network resources that will guarantee the transmission and reception of data streams across a network with the requested bandwidth.
Multiple VLAN Registration Protocol (MVRP)—Provides a mechanism for dynamic maintenance of the contents of Dynamic VLAN Registration Entries for each VLAN IDs, and for propagating the information they contain to other Bridges.
Hierarchical QoS—Provides a two level parent-child policy. With hierarchical QoS, you can specify QoS behavior at multiple policy levels, which provides a high degree of granularity in traffic management.
Creates a checksum record for each stage of the boot loading activity. You can retrieve and compare the checksum record with a Cisco-certified record, to verify if your software image is genuine.
Federal Information Processing Standard Publication 140-2 (FIPS 140-2) and applicable Common Criteria compliance
Cisco IOS XE Denali 16.3.2 on the Cisco Catalyst 3850 Series Switches is being submitted for certification under FIPS 140-2 and Common Criteria compliance with the US Government, Security Requirements for Network Devices.
(For Base Configuration—LAN Base, IP Base, and IP Services)
(For IP Security—IP Services)
Media Access Control Security (MACsec):
256-bit AES MACsec (IEEE 802.1AE) host link encryption) with MACsec Key Agreement (MKA)
256-bit AES MACsec (IEEE 802.1AE) inter-network device encryption with MKA
Extensible Authentication Protocol - Transport Layer Security (EAP-TLS) method support for MKA
MACsec features are now available with IP Base and IP Services license levels.
Available with mGig interfaces. When downshift is enabled, the system automatically downshifts to a lower port speed if the link quality is poor or if the link is continuously down.
MVPN provides the ability to support multicast over a Layer 3 VPN. As enterprises extend the reach of their multicast applications, service providers can accommodate them over their MPLS core network. IP multicast is used to stream video, voice, and data over an MPLS VPN network core.
Individual device credential support, allowing the controller to manage devices that require individual TACACS or RADIUS credentials for access. The credentials are passed to the device securely and the password is not logged.
This feature requires Cisco IOS XE Denali 16.3.2 or a later software release on the device.
Wired Application Visibility and Control (Wired AVC) Flexible NetFlow (FNF)
Support for FNF is now enabled for wired AVC. The feature uses a flow record with an application name as the key, to provide statistics per interface, client, server, and application.
The record is similar to the Easy Performance Monitor (EzPM) application-client-server-stats traffic monitor, which is available in application-statistics and application-performance profiles.
Enables a switch joining an existing stack to be automatically upgraded to the same version as the existing stack, so that the switch can successfully join the existing stack.
Previously, Cisco IOS XE Denali 16.x.x releases supported this feature only on switches running an IOS XE Denali 16.x.x image joining an existing stack with a different Cisco IOS XE Denali 16.x.x image version. Starting with this release, the active switch can resolve a mismatch across Cisco IOS XE Release 3.xE and Cisco IOS XE Denali 16.3.x releases.
For this activity to happen automatically, you should have enabled the software auto-upgrade enable global configuration command, on the active switch. If not, you can start the process manually by entering the request platform software package install auto upgrade privileged EXEC command, on the active switch.
The software image installation process is now optimized:
The space required for installation is reduced—after you have copied the.bin file to flash, only 20MB of additional space is required to complete the installation.
The.bin file is automatically deleted after completion of installation.
Provides fast forwarding path failure detection times for all media types, encapsulations, topologies, and routing protocols. It also provides a consistent failure detection method for network administrators.
A virtual topology that can be used to logically connect devices that are a part your physical network, facilitating simple segmentation constructs to build secure boundaries. Fabric Overlay uses alternative forwarding attributes to provide services such as host mobility and enhanced security, which are additional to normal switching and routing capabilities.
Cisco TrustSec: Virtual Routing and Forwarding Aware (VRF-Aware) Security Group Tag (SGT)
Enables a device to communicate with RADIUS servers through VRF interfaces. This feature allows protected access credential (PAC) and Environment-Data to be requested from the authentication device, Cisco Identity Services Engine (Cisco ISE), when Cisco ISE is in a VRF network.
Starting with this release, the amount of free memory is computed more accurately. The output of the following commands (privileged EXEC mode) displays this information:
show memory platform
show platform resources
show processes memory platform
show platform software status control-processor
show platform software process list switch active R0 summary
Federal Information Processing Standard Publication 140-2 (FIPS 140-2) and the Common Criteria for Information Technology Security Evaluation standard (Common Criteria or CC)
Cisco IOS XE Denali 16.3.1on the Cisco Catalyst 3850 Series Switches is being submitted for certification under FIPS 140-2 and Common Criteria compliance with the US Government, Security Requirements for Network Devices.
IPv4 Multicast over Point-to-Point Generic Routing Encapsulation (GRE) Tunnels
Supports attachment of IPv6 ACLs to configure a secure HTTP server.
Note The existing CLIs that specify (only IPv4) ACLs are supported, but are going to be deprecated. Use the new CLIs that support both IPv4 and IPv6 ACLs instead.
256-bit AES MACsec (IEEE 802.1AE) host link encryption) with MACsec Key Agreement (MKA)
256-bit AES MACsec (IEEE 802.1AE) inter-network device encryption with MKA
Extensible Authentication Protocol - Transport Layer Security (EAP-TLS) method support for MKA
Supports the IEEE 802.1x standard-based Layer 2 encryption with MKA on both uplink (switch-to-switch) and downlink (switch-to-host device) ports for 256-bit level encryption using EAP-TLS and Preshared Key (PSK).
Supported on Cisco Catalyst 3650 Series Mini Switches and the Cisco Catalyst 3650 Series MultiGigabit Switches. The model numbers are listed below:
Combines the performance and capabilities of Layer 2 (data link layer) switching with the proven scalability of Layer 3 (network layer) routing.
MPLS enables service providers to meet the challenges of explosive growth in network utilization while providing the opportunity to differentiate services without sacrificing the existing network infrastructure.
Enables extended secure access in areas outside the wiring closet. It allows you to configure a switch to act as a supplicant to another switch. NEAT utilizes the Client Information Signaling Protocol (CISP) to propagate client MAC addresses and VLAN information between supplicant and authenticator switches.
An Address Resolution Protocol (ARP)-like protocol that dynamically maps a nonbroadcast multiaccess (NBMA) network. With NHRP, systems attached to an NBMA network can dynamically learn the NBMA (physical) address of the other systems that are part of that network, allowing these systems to directly communicate.
NHRP is a client and server protocol where the hub is the Next Hop Server (NHS) and the spokes are the Next Hop Clients (NHCs). The hub maintains an NHRP database of the public interface addresses of each spoke. Each spoke registers its real address when it boots and queries the NHRP database for real addresses of the destination spokes to build direct tunnels.
Yet Another Next Generation (YANG) data-modeling language
Support for the YANG data-modeling language, which replaces the process of manual configuration with a programmatic and standards-based way of writing configurations to any network device. It supports the automation of configuration for multiple switches across the network using data models.
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, –B, 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 indoor and outdoor use, and transmission (Tx) power level increased for indoor, outdoor, and point-to-point transmissions.
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.
AP2800 802.11 ac Wave 2 and AP3800 802.11 ac Wave 2: Cisco Multi-Gig (mGig) Enabled Ethernet Ports
Enables the current network to carry a higher bandwidth using mGig enabled Ethernet Ports. Speeds that cap at 1Gbps can now go upto 2.5Gpbs and 5Gbps speeds. These speeds can be achieved on the existing CAT5e and above type of LAN cables.
Note Flexible Radio Assignment and 160 MH Channel width is not supported.
(IP Base and IP Services)
AVC Support on 802.11 ac Wave2 APs
Support for Application Visibility and Control (AVC) on the following Access Points (APs):
Cisco Aironet 1810w Series APs
Cisco Aironet 1830 Series APs
Cisco Aironet 1850 Series APs
Cisco Aironet 2800 Series APs
Cisco Aironet 3800 Series APs
You can now also capture AVC statistics for the last 48 hours. Use the show platform software fed switch active avc statistics byte-count-window hours 48 raw privilege EXEC command.
(IP Base and IP Services)
Fast Locate with Local Mode
Provides reporting of location performance via data packets RSSI through Local Mode radios through CPU cycle stealing when Cisco Hyperlocation radio module is not installed on an AP. This is available on the following APs:
Cisco Aironet 700 Series APs
Cisco Aironet 1700 Series APs
Cisco Aironet 2600 Series APs
Cisco Aironet 2700 Series APs
Cisco Aironet 3600 Series APs
Cisco Aironet 3700 Series APs
You can now configure Cisco Hyperlocation for an AP group. Previously, Cisco Hyperlocation configuration was applicable to all APs globally
Cisco Hyperlocation Module with Integrated Bluetooth Low Energy (BLE) Radio
Enables transmission of BLE broadcast messages by using up to 5 BLE transmitters. The Cisco Wireless Controller (Cisco WLC) is used to configure the transmission parameters such as interval for the beacons, UUID, and transmission power, per beacon globally for all the access points. Also, the Cisco WLC can configure major, minor, and transmission power value of each access point, thus providing more beacon granularity. This feature works in conjunction with Cisco Hyperlocation Radio Module and the Cisco Hyperlocation feature.
Provide control over the data rates and power (TPC) values. These RF profiles allows you to optimize the RF settings for AP groups which operate in different environments or coverage zones. These profiles can be created for both radio bands - 2.4-GHz and 5-GHz
Support for Remote-LAN. This feature is similar to Wireless LAN (WLAN). While WLAN is used for wireless connection, Remote-LAN is used for wired ports.
Configuring a Remote-LAN profile on the local Gigabit Ethernet ports enables the traffic from wired devices to connect to the WLAN controller.
Cisco 1810W series APs come with three local Gigabit Ethernet ports, one uplink Gigabit Ethernet port and one passive pass-through RJ-45 port.
Web UI support for BLE Beacons and RF Profiles, Cisco Hyperlocation FastLocate
Features introduced and updated on the Web UI in this release:
BLE Beacons (IP Base and IP Services)
RF Profiles (IP Base and IP Services)
Cisco Hyperlocation Fast Locate (IP Base and IP Services)
Cisco Application Visibility for Wired Devices
Wired Alerts (LAN Base, IP Base, and IP Services)

Automatic Boot Loader Upgrade
When you upgrade from any prior IOS 3.xE release to an IOS XE 16.x.x release for the first time, the boot loader may be automatically upgraded, based on the hardware version of the switch. If the boot loader is automatically upgraded, it will take effect on the next reload. 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.
For subsequent IOS XE 16.x.x releases, if there is a new bootloader in that release, it may be automatically upgraded based on the hardware version of the switch when you boot up your switch with the new image for the first time.
Caution Do not power cycle your switch during the upgrade.
Scenario
Automatic Boot Loader Response
If you boot Cisco IOS XE Denali 16.3.5b or Cisco IOS XE Denali 16.3.5 or Cisco IOS XE Denali 16.3.6 or Cisco IOS XE Denali 16.3.7 or Cisco IOS XE Denali 16.3.8 or Cisco IOS XE Denali 16.3.9 for the first time
The boot loader may be upgraded to version 4.66. For example:
CAT3K_CAA Boot Loader (CAT3K_CAA-HBOOT-M) Version 4.66, RELEASE SOFTWARE (P)
During the automatic boot loader upgrade, while booting Cisco IOS XE Denali 16.3.5, you will see the following on the console:
%IOSXEBOOT-Wed-###: (rp/0): Sep 27 20:52:34 Universal 2017 PLEASE DO NOT POWER CYCLE ### BOOT LOADER UPGRADING
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.x.x 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:
Front-end Microcode IMG MGR: found 4 microcode images for 1 device.

Software Install Image to Flash
Note When you upgrade to Cisco IOS XE Denali 16.3.5 the SSH access is lost, because it cannot use the CISCO_IDEVID_SUDI_LEGACY RSA server key. Before upgrade, generate the server key using the crypto key generate rsa command in global configuration mode. To verify whether the RSA server key is available on your device, run the show crypto key command.
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.
Switch# software install file flash:cat3k_caa-universalk9.16.03.05.SPA.bin new force

Switch#
Note Old files listed in the logs should be removed using the request platform software package clean switch all command, after reload
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
switch: 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.
Upgrading from Cisco IOS XE 3.xE to Cisco IOS XE Denali 16.1.x, 16.2.x, or 16.3.x in Bundle Mode
Warning 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 drive. Please refer to the upgrade sections in install mode.
Warning Starting from 16.3.5 release, you will not be able to boot Cisco IOS XE Denali 16.3.5 in bundle mode via flash drive 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 512MB via flash. Please refer to the upgrade sections in install mode.
Upgrading from Cisco IOS XE Denali 16.1.1 to 16.1.x, 16.2.x, or 16.3.x in Install Mode
Follow these instructions to upgrade from Cisco IOS XE Denali 16.1.1 to Cisco IOS XE Denali 16.1.x, 16.2.x, or 16.3.x in Install Mode. In order to do a software image upgrade, you must be booted into IOS using the boot flash:packages.conf.
Clean Up
Step 1 Ensure you have enough space in flash to expand a new image by cleaning up old installation files.
Note Use the switch all option to clean up all switches in your stack.

Software Install Image to Flash
Step 4 Use the request platform software package install switch all file flash: new auto-copy command to install the target image to flash. We recommend copying the image to a TFTP server or the flash drive of the active switch.
If you point to an image on the flash or USB drive of a member switch (instead of the active), you must specify the exact flash or USB drive - otherwise installation fails. For example, if the image is on the flash drive of member switch 3:
request platform software package install switch all file flash-3:cat3k_caa-universalk9.16.03.05.SPA.bin new auto-copy
[3]: Copying flash-3: cat3k_caa-universalk9.16.03.05.SPA.bin from switch 3 to switch 1 2 4

Step 5 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 you copied it to flash.
Step 7 If your switches are configured with auto boot, then the stack will automatically boot up with the new image. If not, you can manually boot flash:packages.conf
Switch: boot flash:packages.conf
Note When you downgrade to a Cisco IOS XE 3.xE image, your boot loader will not automatically downgrade. It will remain updated. The new boot loader can support booting both Cisco IOS XE 3.xE releases as well as Cisco IOS XE Denali16.x releases.
Downgrade from Cisco IOS XE 16.x to Cisco IOS XE 3.xE in Bundle Mode
Follow these instructions to downgrade from Cisco IOS XE 16.x in Bundle mode to an older Cisco IOS XE 3.xE releases in Bundle mode.
Copy New Image to Stack
Step 1 Make sure your TFTP server is reachable from IOS via GigabitEthernet0/0.

Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/2 ms
Step 2 Copy the image from your TFTP server to flash.
Step 9 If your switches are configured with auto boot, the stack will automatically boot up with the new image. If not, you can manually boot flash:cat3k_caa-universalk9.SPA.03.07.02.E.152-3.E2.bin
Note When you downgrade to a Cisco IOS XE 3.xE image, your boot loader will remain updated, and will automatically be downgraded. The new boot loader can support booting both Cisco IOS XE 3.x releases as well as Cisco IOS XE Denali 16.x releases.
Step 10 When the new image boots up, you can verify the version of the new image, by checking show version
Move from Cisco IOS XE 3.xE Bundle Mode to Install Mode
Step 11 Ensure you have enough space in flash to expand a new image by cleaning up old installation files. This command will erase your Cisco IOS XE 3.xE bin image file, so ensure that you copy it to your Active again.

Upgrading RTU Licenses
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:
%STACK_RTU_LICENSE-6-IOSD_LIC_MISMATCH:Switch 5 R0/0: stack_mgr: Switch #5: Current IOSd runs on lanbase license while RTU active license is ipservices. Please configure RTU license to current IOSd license.
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.

Limitations and Restrictions
Limitations for YANG data modeling—A maximum of 20 simultaneous NETCONF sessions are supported.
Limitations for RF Profiles—Configuration with Cisco Prime Infrastructure is not supported. You must use the CLI to configure the feature.
Limitations for Wired AVC:
– NBAR2 (QOS and Protocol-discovery) configuration is allowed only on wired physical ports. It is not supported on virtual interfaces, for example, VLAN, port channel nor other logical interfaces.
– NBAR2 based match criteria ‘match protocol’ is allowed only with marking or policing actions. NBAR2 match criteria will not be allowed in a policy that has queuing features configured.
– ‘Match Protocol’: up to 256 concurrent different protocols in all policies.
– NBAR2 attributes based QOS is not supported (‘match protocol attribute’).
– NBAR2 and Netflow cannot be configured together at the same time on the same interface.
– Only IPv4 unicast (TCP/UDP) is supported.
– AVC is not supported on management port (Gig 0/0)
– NBAR2 attachment should be done only on physical access ports. Uplink can be attached as long as it is a single uplink and is not part of a port channel.
– Performance—Each switch member is able to handle 500 connections per second (CPS) at less than 50% CPU utilization. Above this rate, AVC service is not guaranteed.
– Scale—Able to handle up to 5000 bi-directional flows per 24 access ports.
Restrictions for QoS:
– When configuring QoS queuing policy, the sum of the queuing buffer should not exceed 100%.
– For QoS policies, only switched virtual interfaces (SVI) are supported for logical interfaces.
– QoS policies are not supported for port-channel interfaces, tunnel interfaces, and other logical interfaces.
– QoS marking is not supported on COS-AP (Wave-2 APs) in any Cisco IOS XE Denali 16.x.x release. In these releases, QoS marking is based on table-maps and table-maps are not supported on COS-APs.
Starting with Cisco IOS XE Denali 16.3.1, Centralized Management Mode (CMM) is no longer supported.
MSE 8.x is not supported with Cisco IOS XE Denali 16.x.x.
WIPs is not supported with Cisco IOS XE Denali 16.x.x since the CMX WIPs solution is not available.
You cannot configure NetFlow export using the Ethernet Management port (g0/0).
The maximum committed information rate (CIR) for voice traffic on a wireless port is 132 Mb/sec.
Flex Links are not supported. We recommend that you use spanning tree protocol (STP) as the alternative.
Outdoor access points are supported only when they are in Local mode.
Restrictions for Cisco TrustSec:
– Dynamic SGACL download is limited to 6KB per destination group tag (DGT).
– Cisco TrustSec 802.1x is not supported.
– Cisco TrustSec Critical Auth is not supported.
– Cisco TrustSec can be configured only on physical interfaces, not on logical interfaces.
– Cisco TrustSec for IPv6 is not supported.
– Cisco TrustSec cannot be configured on a pure bridging domain with IPSG feature enabled. You must either enable IP routing or disable the IPSG feature in the bridging domain.
VLAN Restriction: It is advisable to have well-defined segregation while defining data and voice domain during switch configuration and to maintain a data VLAN different from voice VLAN across the switch stack. If the same VLAN is configured for data and voice domains on an interface, the resulting high CPU utilization might affect the device.
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.
Caveats
Caveats describe unexpected behavior in Cisco IOS releases. Caveats listed as open in a prior release are carried forward to the next release as either open or resolved.
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.
NTP-PTP: Invalid PTP time during NTP leap second insertion/deletion
Resolved Caveats in Cisco IOS XE Denali 16.3.1
The following is the list of Cisco IOS XE Denali 16.1.x and Cisco IOS XE Denali 16.2.x caveats that are resolved in Cisco IOS XE Denali 16.3.1. Click on the identifier to view the details of a caveat in the BST.
