If we will not use DNA, what is the smallest line we must buy?

Quick Take

Quick Take: If you will not use Catalyst Center or SD-Access, buy DNA Essentials for 3 years, not Advantage and not 7 years. You cannot delete the line. You can refuse to renew it. SD-WAN controller mode is the design that must keep paying. C9600 and C8500 have no Essentials tier.

Published 2026-09-29. For buyers who must pay the line and want it as small as Cisco allows.

For a China enterprise RFQ, TAOHAN issues a dated quote. Any channel price on that quote is pending confirmation. A 13% VAT special fapiao can be issued with the invoice. If the site will not use Catalyst Center or SD-Access, buy DNA Essentials for 3 years and do not renew. SD-WAN controller mode must renew. C9600 and C8500 have no Essentials tier.

The line is a gate, not a tool you must use

Quick Answer: Cisco DNA on Catalyst 9000 is a subscription you must buy to complete the order, even when you will not use Catalyst Center. The smallest legal gate is DNA Essentials for 3 years. Advantage and a 5-year or 7-year term buy features and years you can decline.

Do not argue that the features are valuable if your design never turns them on. Argue about the gate. First purchase is 3 years, 5 years, or 7 years. A 1-year term is 1x a renewal option, not a new-logo option. Seven years prepays renewals you may never want. Three years is the shortest gate Cisco opens.

The start date can slip by up to 60 days from shipment. If the closet is not live, do not start the clock early. At the end of year three, the default action for a site with no Catalyst Center and no SD-Access is: do not renew. A move from Essentials to Advantage mid-term credits 50 percent of the residual value. That is useful only if you later adopt the higher tier. It is not a reason to start on Advantage.

Which tier matches the design

Quick Answer: Match the tier to what you will run. No Catalyst Center and no SD-Access means Essentials and 3 years, then stop. SD-Access means Advantage. SD-WAN Manager means renew. C9600, C8500, C9550, and C9610 do not offer Essentials, so Advantage is the floor, not an upsell.

Catalyst subscription Advantage includes hardware support and ISE licenses. DNA subscription Advantage does not include ISE. When a quote says Advantage, ask which subscription name is on the line before you compare two offers. They are not the same bundle.

Catalyst 1200 and 1300 are a different small-business family. Cisco's datasheet says there is no license to purchase. That does not remove DNA from a Catalyst 9000 order. It only helps if the closet truly fits that smaller platform.

How to write the shortest legal line

Quick Answer: Name the chassis, confirm it is not an Advantage-only platform, select DNA Essentials for 3 years, delay the start up to 60 days if the site is not ready, and write do-not-renew into the asset record unless SD-WAN Manager is in the design.

1. Step 1. Reject any quote that deletes the subscription. CCW will not book that hardware as configured.
2. Step 2. If the platform has Essentials, buy 3 years of Essentials. If it does not, buy Advantage and say so in the bid note.
3. Step 3. Slide the start date by up to 60 days so you do not pay for months on a shelf.
4. Step 4. Flag SD-WAN controller mode. That design renews. The others do not have to.

Put the same words in the technical deviation sheet: DNA Essentials, 3 years, no default to Advantage for 7 years. A 5-year or 7-year term is a budget choice, not a feature the closet needs.

Typical scenario: a branch that will never join a fabric

Quick Answer: A typical scenario is a buyer staring at a 7-year Advantage line on switches that will only do VLANs. Change it to DNA Essentials for 3 years, delay the start if the racks are still in cardboard, and plan to let the term end. Traffic will still forward. That outcome is documented on the expiry page.

Label this as a typical scenario. The saving is the years and the tier you do not buy, not a deleted line. If someone offers a much smaller number by removing DNA, that quote is a different product. Compare it on the quote-check page, not here.

Platforms that will not shrink to Essentials

Quick Answer: C9600 and C8500 have no Essentials tier, and C9550 and C9610 Networking Subscriptions are Advantage only. On those platforms the smallest line is Advantage at the shortest term, not a fight to invent an Essentials SKU. Say that in the bid so Advantage does not look like padding.

Wireless on Catalyst 9100 follows the same spirit for a new 9800 deployment: a DNA term per AP at purchase, with the AireOS perpetual-license case and EWC DNA-OPTOUT as the narrow exits. The 9800 itself does not need a separate AP license on top. Do not buy a second controller license because a spreadsheet has an empty cell.
