Re: system switch-mode n9k

Adam Vitkovsky · ‎08-28-2018

Hi folks,

I’d like to ask what am I actually getting when running nexus 3032Q in nexus9000 mode with “system switch-mode n9k” please?

Thank you?

Hi Adam,

I don't think you can do the “system switch-mode n9k” on the 3032Q.

https://www.cisco.com/c/en/us/td/docs/switches/datacenter/nexus3000/sw/fundamentals/7x/b_Cisco_Nexus_3000_Series_NX-OS_Fundamentals_Configuration_Guide_7x/b_Cisco_Nexus_3000_Series_NX-OS_Fundamentals_Configuration_Guide_7x_chapter_011.html#task_5F0F1...

Snippet below

The Cisco Nexus 3100 Series switches, except Cisco Nexus 3100-V switches, now support two system modes: the N3K mode and the N9K mode. The N3K mode is the default mode. It uses the same CLI commands as the previous Cisco Nexus 3000 Series and Cisco Nexus 3100 Series NX-OS releases. The N9K mode enables the Cisco Nexus 3100 Series switches to use the Cisco Nexus 9000 Series switches CLI commands. Refer to the Cisco Nexus 9000 Series configuration guides for the Cisco Nexus 9000 Series CLI commands.

Note

The N9K mode is available on the Cisco Nexus 3100 Series switches only and it is not available on the Cisco Nexus 3000 Series switches. Cisco Nexus 3100-V switches supports only N9K CLI.

With the N3k operating in the N9k mode you have bit more flexibility to configure CoPP. The TCAM carving is also different. There is also differences in the QoS implementation.

There may also be a license piece that may come into play when using n9k mode so be aware of that as well.

https://www.cisco.com/c/en/us/td/docs/switches/datacenter/sw/nx-os/licensing/guide/b_Cisco_NX-OS_Licensing_Guide/b_Cisco_NX-OS_Licensing_Guide_chapter_01.html

snippet

The Cisco Nexus 3164Q, 31128PQ, 3232C, and 3264Q switches and the Cisco Nexus 3100 Series switches in N9K mode run Cisco Nexus 9000 Series software and follow the Cisco Nexus 9000 license model. Therefore, these switches require the Layer 3 Enterprise Services Package (rather than the Layer 3 Base Services Package) to support routing protocols.

Hope this help.
