Software Features in Cisco IOS XE Amsterdam 17.1.1

Feature Name

Description, Documentation Link, and License Level Information

Cisco Umbrella Integration

Provides security and policy enforcement at the Domain Name Sever (DNS) level. It enables the administrator to split the DNS traffic and directly send some of the desired DNS traffic to a specific DNS server (DNS server located within the enterprise network).

See Security → Configuring Cisco Umbrella Integration.

(Network Advantage)

Flash MIB instance retrieval count limit increase

The limitation of Flash MIB listing 100 files per partition per device has been removed. Flash MIB can now fetch all the files from the flash file system.

See Network Management → Configuring Simple Network Management Protocol.

(Network Essentials and Network Advantage)

Neighbor Discovery (ND) Inspection Feature Deprecation

The IPv6 ND Inspection feature is deprecated. The Switch Integrated Security Features based (SISF-based) device tracking feature replaces it and offers the same capabilities.

See Security → Configuring IPv6 First Hop Security.

(Network Essentials and Network Advantage)

Opening or Closing SNMP UDP Ports

A security enhancement that enables you to access the Simple Network Management Protocol (SNMP) UDP ports only after one of the requisite commands is configured. This design change secures and opens the ports only when required and prevents a device from listening to a port unnecessarily.

See Network Management → Configuring Simple Network Management Protocol.

(Network Essentials and Network Advantage)

Per-Port MTU Configuration

Introduces support for port level and port channel level maximum transmission unit (MTU) configuration. With Per-Port MTU configuration, you can configure different MTU values for different interfaces as well as for different port channel interfaces.

See Interface and Hardware Components → Configuring Per-Port MTU.

(Network Essentials and Network Advantage)

Programmability

The following programmability features are introduced in this release:

  • The candidate configuration supports the confirmed commit capability. This implementation is as specified in RFC 6241 for the confirmed commit capability which, when issued, sets the running configuration to the current contents of the candidate configuration and starts a confirmed commit timer. The confirmed commit operation will be rolled back if the commit is not issued within the timeout period. The default timeout period is 600 seconds or 10 minutes.

  • Model-Driven Telemetry Event Notification Support: Introduces support for event notifications over the NETCONF protocol.

  • RESTCONF YANG-Patch Support: Introduces support for YANG-Patch media type as specified by RFC 8072.

  • TLS for gRPC Dial-Out: Introduces support for TLS for gRPC dial-out.

  • Cisco TrustSec uses the REST-based transport protocol for SGACL policy provisioning and data download from Cisco Identity Services Engine (ISE). The REST-based protocol is more secure, and provides reliable, and faster policy and environment data provisioning, than the RADIUS protocol that is used in previous releases. Both the REST API-based and RADIUS-based download of Cisco TrustSec data is supported. However, only one protocol can be active on a device. In Cisco IOS XE Amsterdam 17.1.1, REST-based protocol is the default.

  • YANG Data Models—For the list of Cisco IOS XE YANG models available with this release, navigate to: https://github.com/YangModels/yang/tree/master/vendor/cisco/xe/1711.

    Some of the models introduced in this release are not backward compatible. For the complete list, navigate to: https://github.com/YangModels/yang/tree/master/vendor/cisco/xe/1711/BIC.

    Revision statements embedded in the YANG files indicate if there has been a model revision. The README.md file in the same GitHub location highlights changes that have been made in the release.

See Programmability.

(Network Essentials and Network Advantage)

New on the Web UI

  • Cisco Umbrella Integration

  • New default credentials for WebUI

  • Power Over Ethernet (POE)

  • Intermediate System- Intermediate System(IS-IS)

  • Routing Information Protocol (RIP)

  • Virtual Terminal Lines (VTY)

Use the WebUI for:

  • Cisco Umbrella Integration—Supports integration with the cloud-based security platform–Cisco Umbrella. It provides a first line of defense by inspecting the Domain Name System (DNS) query and preventing a user from accessing a site if it is known to be malicious. Using the WebUI, the security administrator configures policies on the Cisco Umbrella Integration cloud to either allow or deny traffic towards the fully qualified domain name (FQDN).

  • New default credentials for WebUI—The login credentials for connecting to the device from the WebUI at Day 0 have been updated. This is available in the respective platform hardware guide.

  • Power Over Ethernet (POE)—The dashboard displays a dashlet for POE utilization for the switch.

  • Intermediate System- Intermediate System(IS-IS)—Supports Integrated Intermediate System- Intermediate System(IS-IS) routing protocol configuration for improved routing of data packets to their destination based on the best route.

  • Routing Information Protocol (RIP)—Supports RIP configuration for improved routing of data packets to their destination based on the hop count.

  • Virtual Terminal Lines (VTY)—Supports vty lines configuration in device setup, to allow a maximum number of simultaneous access to the device, remotely, through Telnet or SSH.

Important Notes

Accessing Hidden Commands

This section provides information about hidden commands in Cisco IOS XE and the security measures that are in place, when they are accessed. Hidden commands are not equipped with CLI help. This means that entering a question mark (?) at the system prompt does not display the list of available commands. These commands are only meant to assist Cisco TAC in advanced troubleshooting and are not documented either.

Hidden commands are available under:

  • Category 1—Hidden commands in privileged or User EXEC mode. Begin by entering the service internal command to access these commands.

  • Category 2—Hidden commands in one of the configuration modes (global, interface and so on). These commands do not require the service internal command.

Further, the following applies to hidden commands under Category 1 and 2:

  • The commands have CLI help. Entering enter a question mark (?) at the system prompt displays the list of available commands.

    Note: For Category 1, enter the service internal command before you enter the question mark; you do not have to do this for Category 2.

  • The system generates a %PARSER-5-HIDDEN syslog message when the command is used. For example: 
    *Feb 14 10:44:37.917: %PARSER-5-HIDDEN: Warning!!! 'show processes memory old-header ' is a hidden command. 
Use of this command is not recommended/supported and will be removed in future.

Apart from category 1 and 2, there remain internal commands displayed on the CLI, for which the system does NOT generate the %PARSER-5-HIDDEN syslog message.


Important

We recommend that you use any hidden command only under TAC supervision.

If you find that you are using a hidden command, open a TAC case for help with finding another way of collecting the same information as the hidden command (for a hidden EXEC mode command), or to configure the same functionality (for a hidden configuration mode command) using non-hidden commands.

Default Behaviour

Beginning from Cisco IOS XE Gibraltar 16.12.5 and later, do not fragment bit (DF bit) in the IP packet is always set to 0 for all outgoing RADIUS packets (packets that originate from the device towards the RADIUS server).

Note

 
The system reloads automatically after executing the install add file activate commit command. You do not have to manually reload the system.

Step 4

Reload

  1. boot flash:

    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 the software image, the boot loader does not automatically downgrade. It remains updated.

  2. show version

    After the image boots up, use this command to verify the version of the new image.

    Note

     
    When you boot the new image, the boot loader is automatically updated, but the new bootloader version is not displayed in the output until the next reload.
    The following sample output of the show version command displays the Cisco IOS XE Gibraltar 16.12.1 image on the device:
    Switch# show version
Cisco IOS XE Software, Version 16.12.01

Licensing

For information about licenses required for the features available on Cisco Catalyst 9000 Series Switches, see Configuring Licenses on Cisco Catalyst 9000 Series Switches.

All licensing information relating to Cisco Catalyst 9000 Series Switches are available on this collection page: Cisco Catalyst 9000 Switching Family Licensing.

Available Licensing Models and Configuration Information

  • Cisco IOS XE Fuji 16.9.2 to Cisco IOS XE Amsterdam 17.3.1: Smart Licensing is the default and the only supported method to manage licenses.

  • Cisco IOS XE Amsterdam 17.3.2a and later: Smart Licensing Using Policy, which is an enhanced version of Smart Licensing, is the default and the only supported method to manage licenses.

Limitations and Restrictions

  • Control Plane Policing (CoPP)—The show run command does not display information about classes configured under system-cpp policy, when they are left at default values. Use the show policy-map system-cpp-policy or the show policy-map control-plane commands in privileged EXEC mode instead.

  • Hardware limitations

    • Management Port—You cannot modify the configured port speed, duplex mode and flow control and disable auto-negotiation on the Ethernet Management port (GigabitEthernet0/0). Port speed and duplex mode can only be changed from a peer port.

    • Network Module — When the C9200-NM-4X network module is plugged into the C9200 SKUs of the Cisco Catalyst 9200 Series Switches, the downlink interface remains in down state until the network module is recognized by the switch. The time taken for the switch to recognize the network module is longer in comparison to the time taken by the switch to recognize other interconnected devices.

    • If the 1-meter and 1.5-meter 10-GBase-CX1 cables, which are connected on the 10-G ports of the Catalyst 9200L switches, are connected to the 10-G peer ports of the Catalyst 9200L or Catalyst 9200 switches, the peer device might go into the error-disabled state because of link flapping if the local device is restarted. As a workaround, run the shut and no shut commands on the error-disabled peer interfaces.

  • QoS restrictions

    • 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.

  • Secure Shell (SSH)

    • Use SSH Version 2. SSH Version 1 is not supported.

    • When the device is running SCP and SSH cryptographic operations, expect high CPU until the SCP read process is completed. SCP supports file transfers between hosts on a network and uses SSH for the transfer.

      Since SCP and SSH operations are currently not supported on the hardware crypto engine, running encryption and decryption process in software causes high CPU. The SCP and SSH processes can show as much as 40 or 50 percent CPU usage, but they do not cause the device to shutdown.

  • Stacking

    • Stacking is supported on Cisco Catalyst 9200 Series Switches; A switch stack supports up to eight stack members. However, you cannot stack C9200 SKUs with C9200L SKUs

      The supported stacking bandwidth on C9200L SKUs is up to 80Gbps; on C9200 SKUs, this is up to 160Gbps.

    • Auto upgrade for a new member switch is supported only in the install mode.

  • TACACS legacy command: Do not configure the legacy tacacs-server host command; this command is deprecated. If the software version running on your device is Cisco IOS XE Gibraltar 16.12.2 or a later release, using the legacy command can cause authentication failures. Use the tacacs server command in global configuration mode.

  • USB Authentication—When you connect a Cisco USB drive to the switch, the switch tries to authenticate the drive against an existing encrypted preshared key. Since the USB drive does not send a key for authentication, the following message is displayed on the console when you enter password encryption aes command:
    Device(config)# password encryption aes
Master key change notification called without new or old key

  • 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.

  • YANG data modeling limitation—A maximum of 20 simultaneous NETCONF sessions are supported.

  • Embedded Event Manager—Identity event detector is not supported on Embedded Event Manager.

  • Upgrading the software image from Cisco IOS XE Gibraltar 16.12.x to any of the later releases can result in a persistent database operation failure and after which the persistent database cannot be restored.

    To avoid the persistent database operation failure, use the dir bootflash:.dbpersist command to list all DB persist files and then use the delete bootflash:/.dbpersist/folder_name/file_name and bootflash:/.dbpersist/folder_name/file_name.meta command to delete individual database and meta files from each persistent database folder.

  • The File System Check (fsck) utility is not supported in install mode.

  • Switch Web UI allows configuration of data VLANs only and not voice VLANs. If you remove a voice VLAN configured to an interface using the Web UI, then all data VLANs associated with the interface are also removed by default.
