DNA Advantage— Includes features available with the DNA Essentials license and more.
To find information about platform support and to know which license levels a feature is available with, use Cisco Feature Navigator. To access Cisco Feature Navigator, go to https://cfnng.cisco.com. An account on cisco.com is not required.
License Types
The following license types are available:
-
Permanent—for a license level, and without an expiration date.
-
Term—for a license level, and for a three, five, or seven year period.
-
Evaluation—a license that is not registered.
License Levels - Usage Guidelines
-
Base licenses (Network Essentials and Network-Advantage) are ordered and fulfilled only with a permanent license type.
-
Add-on licenses (DNA Essentials and DNA Advantage) are ordered and fulfilled only with a term license type.
-
An add-on license level is included when you choose a network license level. If you use DNA features, renew the license before term expiry, to continue using it, or deactivate the add-on license and then reload the switch to continue operating with the base license capabilities.
-
When ordering an add-on license with a base license, note the combinations that are permitted and those that are not permitted:
Table 1. Permitted Combinations DNA Essentials
DNA Advantage
Network Essentials
Yes
No
Network Advantage
Yes5
Yes
5 You will be able to purchase this combination only at the time of the DNA license renewal and not when you purchase DNA-Essentials the first time. -
Evaluation licenses cannot be ordered. They are not tracked via Cisco Smart Software Manager and expire after a 90-day period. Evaluation licenses can be used only once on the switch and cannot be regenerated. Warning system messages about an evaluation license expiry are generated only 275 days after expiration and every week thereafter. An expired evaluation license cannot be reactivated after reload. This applies only to Smart Licensing. The notion of evaluation licenses does not apply to Smart Licensing Using Policy.
Cisco Smart Licensing
Cisco Smart Licensing is a flexible licensing model that provides you with an easier, faster, and more consistent way to purchase and manage software across the Cisco portfolio and across your organization. And it’s secure – you control what users can access. With Smart Licensing you get:
-
Easy Activation: Smart Licensing establishes a pool of software licenses that can be used across the entire organization—no more PAKs (Product Activation Keys).
-
Unified Management: My Cisco Entitlements (MCE) provides a complete view into all of your Cisco products and services in an easy-to-use portal, so you always know what you have and what you are using.
-
License Flexibility: Your software is not node-locked to your hardware, so you can easily use and transfer licenses as needed.
To use Smart Licensing, you must first set up a Smart Account on Cisco Software Central (http://software.cisco.com).
Important |
Cisco Smart Licensing is the default and the only available method to manage licenses. |
For a more detailed overview on Cisco Licensing, go to cisco.com/go/licensingguide.
Deploying Smart Licensing
The following provides a process overview of a day 0 to day N deployment directly initiated from a device. Links to the configuration guide provide detailed information to help you complete each one of the smaller tasks.
Procedure
Step 1 |
Begin by establishing a connection from your network to Cisco Smart Software Manager on cisco.com. In the software configuration guide of the required release, see System Management → Configuring Smart Licensing → Connecting to CSSM |
Step 2 |
Create and activate your Smart Account, or login if you already have one. To create and activate Smart Account, go to Cisco Software Central → Create Smart Accounts. Only authorized users can activate the Smart Account. |
Step 3 |
Complete the Cisco Smart Software Manager set up. |
With this,
-
The device is now in an authorized state and ready to use.
-
The licenses that you have purchased are displayed in your Smart Account.
Using Smart Licensing on an Out-of-the-Box Device
If an out-of-the-box device has the software version factory-provisioned, all licenses on such a device remain in evaluation mode until registered in Cisco Smart Software Manager.
In the software configuration guide of the required release, see System Management → Configuring Smart Licensing → Registering the Device in CSSM
Scaling Guidelines
For information about feature scaling guidelines, see the Cisco Catalyst 9200 Series Switches datasheet at:
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:
-
Power Supplies — Only the following power supplies are supported. Power supplies other than the following may or may not work properly.
-
PWR-C5-125WAC
-
PWR-C5-600WAC
-
PWR-C5-1KWAC
-
-
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.
-
-
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:
-
A switch stack supports up to eight stack members.
-
Auto upgrade for a new member switch is supported only in the install mode.
-
-
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.
-
The File System Check (fsck) utility is not supported in install mode.
Caveats
Caveats describe unexpected behavior in Cisco IOS-XE releases. Caveats listed as open in a prior release are carried forward to the next release as either open or resolved.
Cisco Bug Search Tool
The Cisco Bug Search Tool (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 BST is designed to improve the effectiveness in network risk management and device troubleshooting. The tool has a provision to filter bugs based on credentials to provide external and internal bug views for the search input.
