C9300-DNA-A-48S-3Y Description

The C9300-DNA-A-48S-3Y is a Cisco DNA Advantage software subscription for 48-port Cisco Catalyst 9300 1G fiber switches with modular uplinks. It carries a 3-year term and sits in the 48-port fiber group, separate from the copper subscription line. Advantage is the tier SD-Access requires, and Cisco publishes no downgrade from Advantage to Essentials.

Key Features

Advantage-Tier Feature Set

Advantage adds SD-Access, IPsec, app hosting, Encrypted Traffic Analytics and network assurance on top of Essentials.

Fiber-Specific License Line

Cisco gives 1G fiber hosts their own 48-port license series, so a copper 48-port subscription does not apply to these switches.

Three-Year Term

The 3-year term is one of three Cisco offers, with 5 and 7-year versions of the same fiber license for longer coverage.

Matching Tier Rule

A new subscription must be the same tier as the Network Stack license on the switch, which keeps Advantage subscriptions on Network Advantage hardware.

Included Cloud Services

ThousandEyes Network and Application Synthetics and Cisco Spaces Extend are bundled with the Advantage subscription for its term.

Smart Licensing Records

Entitlements sit in the Smart Account and its virtual accounts, which lets a team assign licenses by site or department.

Application Scenarios

Fiber Aggregation Of Access Rooms

A building that terminates fiber runs from many rooms on 48-port Catalyst 9300 SFP switches uses the subscription to license each switch at the Advantage tier.

SD-Access With Fiber Downlinks

Where an SD-Access fabric reaches its endpoints over 1G fiber, the 48-port fiber switches at the edge need Advantage, which this subscription supplies.

Term Alignment With Support

A team that buys hardware support for 3 years can set the software term to match, which avoids a gap between the two contracts.

C9300-DNA-A-48S-3Y is the DNA Advantage, 3-year license for 48-port 1G fiber Catalyst 9300 switches, while C9300-DNA-A-48-3Y carries the same tier and term for the 48-port copper group, so the host model decides between them. Hardware on Network Essentials takes C9300-DNA-E-48S-3Y instead, since a new order keeps the subscription at the same tier as the Network Stack license. Terms beyond three years use C9300-DNA-A-48S-5Y, the default term in the configurator. Advantage is also the tier that SD-Access requires, and Cisco lists no downgrade PID from Advantage to Essentials.

Ordering Checklist

  • License group: Use the 1G fiber license line, C9300-DNA-A-48S-3Y, -5Y or -7Y, for the 48-port 1G fiber hosts. Cisco keeps separate license lines for 1G fiber and copper models, and a copper 48-port PID does not match a fiber host.
  • Tier: Keep DNA Advantage, matching the -A suffix of the switch. 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

  • Does Cisco Smart Licensing apply to C9300-DNA-A-48S-3Y?

    Yes, C9300-DNA-A-48S-3Y uses Cisco Smart Licensing and requires a Smart Account during purchase. The account must belong to the intended owner of the 48-port fiber entitlement.
  • How does C9300-DNA-A-48S-3Y differ from C9300-DNA-E-48S-3Y?

    C9300-DNA-A-48S-3Y provides DNA Advantage, whereas C9300-DNA-E-48S-3Y provides DNA Essentials. Both PIDs cover 48-port fiber Catalyst 9300 models for a 3-year term.
  • Which model mismatch rules out C9300-DNA-A-48S-3Y?

    C9300-DNA-A-48S-3Y is excluded when the switch is copper, 24-port, fixed-uplink, or outside the Catalyst 9300 family. A DNA Essentials requirement also changes the PID.
  • What is C9300-DNA-A-48S-3Y?

    C9300-DNA-A-48S-3Y is a 3-year Cisco DNA Advantage subscription license for 48-port fiber Catalyst 9300 models with modular uplinks. It supplies entitlement coverage rather than physical switching hardware.
  • What hardware does C9300-DNA-A-48S-3Y license?

    C9300-DNA-A-48S-3Y licenses 48-port fiber Catalyst 9300 models with modular uplinks. The 48S model group is separate from the 48-port copper license scope.
  • Which switch family is compatible with C9300-DNA-A-48S-3Y?

    C9300-DNA-A-48S-3Y is compatible with the 48-port fiber model group in the Cisco Catalyst 9300 Series. It is not a Catalyst 9300L fixed-uplink subscription SKU.
