IP Pool Types

[de1denta]

Hi All,

When adding a reserved IP pool within DNAC, I am prompted to select a pool Type with options Generic, LAN, Management, Service or WAN-Internal. I have hunted though Cisco documentation but I cant find the relevance of this field. It is required a certain feature/function of DNA or is it just for information?

Thanks,

Hey,

Yes the pool types  have a purpose and meaning. It should be added to the public facing documentation.

For now (April, 2019) in lieu of official cisco.com documentation, in Cisco DNA Centre 1.2.10:

Generic – Wired and wireless endpoint attachment to SD-Access fabric, and fabric enabled wireless AP attachment to SD-Access fabric

LAN – LAN Automation (for SD-Access underlay specifically) and SD-Access extended node

Management, Service, WAN-Internal are used for NFV provisioning per site on ENCS

HTH, Jerome

Hey Jerome,

That's great, thanks for this.

Also regarding pool assignments, is it ok to assign a pool to a site that is not actually used or referenced in DNA? For example, I have subnet of 192.168.1.0/24 that is allocated to a site that I used for the manual underlay configuration of my border routers (P2P links, loopback etc). Is it ok to reserve this range in DNA centre?

Hello Will (assumption!),

Sure you can, but I can't think or a reason to. What are you trying to accomplish?

I think Its more for visibility than anything so that other admins do not try and allocate an IP pool that is already in use. We dont have an IPAM server so this seems like a good alternative as all of our subnet allocations will be in one place, whether actually used by SDA or not.

OK, sure thing, you can. But do note that if you reserve a pool then it's possible someone might use it i.e. once it's in DNA Centre and reserved for a location then it's selectable in the host onboarding screen.

Also note there is a limit to the number of IP pools that can be deployed, see table 3. FYI the limit should increase in future releases of DNA Centre: https://www.cisco.com/c/dam/en/us/td/docs/solutions/CVD/Campus/CVD-Software-Defined-Access-Design-Sol1dot2-2018DEC.pdf
