Key Features

Advantage-Tier Feature Set

The tier adds SD-Access, IPsec, app hosting, Encrypted Traffic Analytics and network assurance on top of the Essentials feature set.

Three-Year Term

The subscription runs for 3 years, the shortest of the 3, 5 and 7-year terms Cisco offers for Catalyst 9300 switches.

1G Fiber Port Group

Cisco keeps a separate license line for 24-port 1G fiber hosts, so this subscription does not apply to copper models of the same port count.

Bundled ThousandEyes And Spaces Extend

A 3, 5 or 7-year Advantage subscription includes ThousandEyes Network and Application Synthetics and a Cisco Spaces Extend entitlement for the same term.

Software-Only Support

The Cisco DNA subscription covers software support with a 1-hour TAC response target for severity 1 and 2 requests, and does not include an ISE license.

Smart Account Entitlement

The license is recorded in the customer’s Smart Account, where Smart Licensing keeps it available to move between Catalyst 9300 switches.

Application Scenarios

Fiber Closets In Campus Buildings

In a campus building that links its access switches over SFP fiber, the subscription gives each 24-port Catalyst 9300 1G fiber switch the DNA Advantage feature set.

SD-Access Edge Switches

A campus network that builds an SD-Access fabric needs the Advantage tier on its access switches, and this subscription covers the 24-port fiber members of that fabric.

Three-Year Renewal Cycle

A site whose existing 24-port fiber Catalyst 9300 subscription is expiring can renew for 3 years and line the term up with a hardware support contract of the same length.

C9300-DNA-A-24S-3Y is the DNA Advantage, 3-year license for 24-port 1G fiber Catalyst 9300 switches, while C9300-DNA-A-24-3Y carries the same tier and term for the 24-port copper group, so the host model decides between them. Sites that run Network Essentials hardware should order C9300-DNA-E-24S-3Y instead, because a new order keeps the subscription at the same tier as the Network Stack license. A project that needs coverage beyond three years moves to C9300-DNA-A-24S-5Y, the term the configurator selects by default. Cisco publishes no downgrade PID from Advantage to Essentials, so the tier is worth settling before the order.

Ordering Checklist

  • License group: Use the 1G fiber license line, C9300-DNA-A-24S-3Y, -5Y or -7Y, for the 24-port 1G fiber hosts. Cisco keeps separate license lines for 1G fiber and copper models, and a copper 24-port PID does not match a fiber host.
  • Tier: Keep DNA Advantage, matching the -A suffix of the switch. The configurator opens on Advantage, but new orders must keep the subscription at the same tier as the Network Stack license.
  • Term: Select 3Y in place of the 5-year default. The configurator defaults to a 5-year term, so a 3-year entitlement has to be selected.
  • Smart Account: Use an existing Smart Account, or create a new one at purchase. Catalyst 9300 licenses are stored in the Smart Account, and the order cannot be placed without one.

Questions & Answers

  • How does C9300-DNA-A-24S-3Y define its 24-port coverage?

    C9300-DNA-A-24S-3Y covers 24-port 1G fiber Catalyst 9300 models with modular uplinks. The 24S scope separates this license from the corresponding 24-port copper subscription.
  • Can C9300-DNA-A-24S-3Y be assigned to a copper Catalyst 9300?

    No, C9300-DNA-A-24S-3Y is scoped to 24-port fiber Catalyst 9300 models with modular uplinks. The copper model group uses C9300-DNA-A-24-3Y instead.
  • Is a Smart Account required for C9300-DNA-A-24S-3Y?

    Yes, C9300-DNA-A-24S-3Y requires a Smart Account during purchase and uses Cisco Smart Licensing. The entitlement owner and existing subscription state should be checked for renewals or corrections.
  • Which difference separates C9300-DNA-A-24S-3Y from C9300-DNA-E-24S-3Y?

    C9300-DNA-A-24S-3Y carries DNA Advantage, while C9300-DNA-E-24S-3Y carries DNA Essentials. Both cover the 24-port fiber Catalyst 9300 model group for a 3-year term.
  • Which hardware should not use C9300-DNA-A-24S-3Y?

    C9300-DNA-A-24S-3Y should not be used for copper, 48-port, or fixed-uplink switches. It is also wrong when the approved subscription tier is DNA Essentials.
  • What role does C9300-DNA-A-24S-3Y play?

    C9300-DNA-A-24S-3Y is a 3-year Cisco DNA Advantage subscription for 24-port fiber Catalyst 9300 models with modular uplinks. It is a software entitlement, not switch hardware.
