The Cisco 3900 Data License (SL-39-DATA-K9) is a perpetual software entitlement that unlocks advanced data throughput and routing features on Cisco 3900 Series ISR routers.
The SL-39-DATA-K9 license is supported on all Cisco 3900 Series ISR G2 routers (e.g., 3925, 3945) running Cisco IOS XE software with the appropriate license package.
SL-39-DATA-K9 activates advanced Layer 3 routing, high-performance data forwarding, MPLS, QoS and other data-centric features on Cisco 3900 routers.
You can order SL-39-DATA-K9 through authorized Cisco partners or directly via the Cisco Commerce portal using the SKU SL-39-DATA-K9.
Upload the .lic file to flash, issue the 'license install flash:SL-39-DATA-K9.lic' command, then reload the router to activate the Data License.
The SL-39-DATA-K9 license is perpetual, providing permanent access to data features without recurring license fees.
Yes. You can migrate SL-39-DATA-K9 to performance-on-demand or security K9 licenses via Cisco’s license upgrade portal.
SL-39-DATA-K9 is a perpetual data feature license, while performance-on-demand is a time-limited license that temporarily boosts router throughput.
A service contract (e.g., SMARTnet) is not required for activation but is highly recommended for ongoing software updates and technical support.
Execute 'show license all' or 'show platform hardware throughput level' in CLI to confirm the SL-39-DATA-K9 license status and throughput level.
Without SL-39-DATA-K9, your Cisco 3900 router operates at base throughput limits, causing traffic shaping or packet drops if you exceed that threshold.
No. Technical support requires a valid Cisco support contract; the SL-39-DATA-K9 license itself does not include support services.
Yes. Cisco allows perpetual licenses to be transferred between devices via the Cisco Software Licensing Portal following the standard transfer process.
SL-39-DATA-K9 is perpetual and does not require renewal. Separate support contracts (SMARTnet) may be renewed independently.
Official documentation is available on Cisco’s website under the Cisco 3900 Series licensing section and the Cisco IOS XE Software Configuration Guides.
