Switch port configuration where DNAC (DN2-HW-APL-L) is connected

[Pranav Mhatre]

Hello All,

Target - 

I will be creating cluster of 3 DN2-HW-APL-L -> 56 core boxes.

Question - Switch port to which  Enterprise and Cluster port of DNAC will be connected should be trunk or access?

I came across below line in - 

Cisco DNA Center Second Generation Appliance Installation Guide, Release 1.3

"The switch port on Cisco DNA Center second generation appliances must be set to access mode in order to function properly. Trunk mode is not supported, as it is on first generation appliances

"

But above note is it applicable to all ports or only for Switch port to which CIMC port will be connected.

Regards,

Pranav

Hi Pranav,

for all ports (Enterprise, Cluster, Management [optional], Cloud[optional] and CIMC[optional-but highly recommended]).

Hello Benjamin,

Thank you for reply. There was known issue in 1st generation that if we do not configure enterprise port as trunk then we may lose GUI access of DNAC box.

Have you experienced this issue in your setup for 2nd generation box with access port ?

Hi Pranav,

I personaly have not faced this issue on our customers installations while using 2nd generation box. But may someone else in this community faced this issue? May you have a look at the cisco bug search tool :)

I did not come across any known bugs for 2nd generation related to this issue. However as this is new box sometimes bugs are reported late.

Thank you for your expertise.

Hello,

Thank you for reply.

If I am correct snap which you attached is of 1st generation DNAC box. Because in 2nd generation box we do not have to do VLAN config in DNAC box.

I came across below note in installation guide -

Unlike the previous generation of Cisco DNA Center appliances, second generation appliances do not use a virtual interface card (VIC). You do not need to configure the network interface card (NIC) that comes installed on your second generation appliance to support high throughput in Cisco IMC, as this is already enabled by default

Hello @Pranav Mhatre 

Hopefully, you are doing well!

configure the Switch port as an access port with normal configurations.

You can visit this link below, I have written about the implementation steps for Cisco Digital Network Architecture including the switch port configuration.
