DNA Centre installation

[benolyndav]

Hi

can anyone advise the two /21 subnets reuqired for services subnet and cluster services subnet are these addresses just used locally within DNA itself or do these ranges need to be routable and reachable.???

Thanks

Hi,

please have a look at this Guide: https://www.cisco.com/c/en/us/td/docs/cloud-systems-management/network-automation-and-management/dna-center/2-1-2/install_guide/2ndGen/b_cisco_dna_center_install_guide_2_1_2_2ndGen/m_plan_deployment_2_1_2_2ndgen.html

Topic: Required IP Addresses and Subnets

And https://www.cisco.com/c/en/us/td/docs/cloud-systems-management/network-automation-and-management/dna-center/2-1-2/install_guide/2ndGen/b_cisco_dna_center_install_guide_2_1_2_2ndGen/m_configure_appliance_mcw_2_1_2_2ndgen.html

Step 13 for an example

If you are doing a fresh install, I recommend downloading the ISO for a 2.x release.  Then, these /21 subnets will be automatically filled in with some 169.x.x.x addresses and you no longer need to reserve them from your company's IP addressing pool.  This only applies to fresh installs, not upgrades to 2.x from 1.x releases.

The "Reimage the Appliance" section should help:
