Cisco N9300 Series Smart Switches

The Cisco N9300 Series Smart Switches are integrated network devices designed for scalable, secure, and efficient data center operations. They combine advanced networking and security features with hardware acceleration and software flexibility, embedding stateful security powered by Cisco Hypershield directly into the network fabric.

Cisco N9300 Series Smart Switches utilize Cisco® Silicon One® E100 ASIC for high-performance switching and DPUs for enhanced security and services. The family includes 100G and 25G switches with 800G DPU acceleration. Models such as the Cisco Nexus N9348Y2C6D-SE1U and N9324C-SE1U offer exceptional flexibility and performance, making them ideal Top of Rack (ToR) solutions for VXLAN-EVPN, BGP fabrics, and Multisite deployments. These switches can be deployed as leaf switches, border leaf, or border gateways, enabling customers to build adaptable and high-performing data center architectures.

The Cisco N9300 Series Smart Switches offer converged switching and routing services.

For product specifications, see Cisco N9300 Series Smart Switch Data Sheet.

Software Features

Guides listed in the below table contains contents specific only to Cisco NX-OS Release 10.6(2s).

 

Release Image

Note:     Starting from 10.5(3)F, Cisco NX-OS no longer provides a separate EPLD image. Instead, the EPLD image is bundled with all NX-OS images and so the image sizes are correspondingly larger.

In Cisco NX-OS Release 10.6(2s), the following 64-bit image is supported:

●     The 64-bit Cisco NX-OS image filename with “nxos64-s1-dpu” as the prefix (for example, nxos64-s1-dpu.10.6.2s.F.bin) is supported and it is mandatory on Cisco N9300 Series Smart Switches.

 

Note:     The 32-bit image is no longer supported.

Upgrade and Downgrade

To perform a software upgrade or downgrade, follow the instructions in the Cisco Nexus 9000 Series NX-OS Software Upgrade and Downgrade Guide, Release 10.6(x).

Note:     Only Disruptive Upgrade is supported. See Disruptive Upgrade.

Note:     Upgrading the Cisco N9324C-SE1U switch from NX-OS Release 10.5(3s) to NX-OS Release 10.6(1s) is not recommended if the service-acceleration feature is in use. This feature is not supported in NX-OS Release 10.6(1s).

To perform an upgrade from release 10.5(3s) to 10.6(2s), follow these instructions:

1.     Back up the current configuration: copy running-config bootflash:config1

2.     Start the upgrade: install-all to 10.6(2s) with the no reload option: install all nxos <image> no-reload

Note:     This implicitly copies running-config to startup-config, so a write erase is required.

3.     Erase previous startup configuration: write erase

4.     Reload the system: reload

5.     Prepare the configuration: Update the config1 file with any changes needed for compatibility with 10.6(2s).

6.     Apply the updated configuration: copy bootflash:config1 running-config

7.     Save the configuration: copy running-config startup-config

To perform a software upgrade from 10.6(1s) or 10.6(2)F to 10.6(2s), follow these instructions:

1.     Start the upgrade: install all nxos <image-name>

2.     Update the service acceleration configuration in 10.6(2s). For configuration details, see the specific service acceleration configuration guide.

3.     Save the configuration: copy running-config startup-config
