See IP Routing.
(Network Essentials and Network Advantage) |
IPv6: OSPF Limit on Number of Redistributed Routes (C9200) |
Enables you to configure a maximum number of prefixes (routes) that can be redistributed into OSPFv3 from other protocols or other OSPFv3 processes. Such a limit helps prevent the device from being flooded by too many redistributed routes.
See IP Routing → Configuring OSPFv3 Limit on Number of Redistributed Routes.
(Network Essentials and Network Advantage) |
IPv6: RFC 5453 Reserved IPv6 Interface Identifiers (C9200) |
An autoconfigured IPv6 address will contain interface identifiers that are not part of the reserved range of interface identifiers specified in RFC 5453.
See IP Multicast Routing → IP Multicast Routing Technology Overview.
(Network Essentials and Network Advantage) |
IPv6 Downloadable ACL (DACL) (C9200) |

(Network Essentials and Network Advantage ) |
Password Configuration: Secure Password Migration (C9200 and C9200L) |
Introduces support for migration of type 0 and type 7 usernames and passwords to type 6. Password protection restricts access to a network or network device. Encrypting passwords provides an additional layer of security, particularly for passwords that cross the network or are stored on a TFTP server. Starting with this release, the switch supports automatic conversion of usernames and passwords with type 0 and type 7 encryption, to type 6 encryption. Type-6 is a strong, reversible 128-bit Advanced Encryption Standard (AES) password encryption. To start using type-6 encryption, you must enable the AES password encryption feature and configure a primary encryption key, which is used to encrypt and decrypt passwords.
See Security → Controlling Switch Access with Passwords and Privilege Levels.

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
-
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.
-
-
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.
-
Secure Password Migration—Type 6 encrypted password is supported from Cisco IOS XE Gibraltar 16.10.1 and later releases. Autoconversion to password type 6 is supported from Cisco IOS XE Gibraltar 16.11.1 and later releases.
If the startup configuration has a type 6 password and you downgrade to a version in which type 6 password is not supported, you can/may be locked out of the device.
-
The File System Check (fsck) utility is not supported in install mode.
Caveats
