Cisco 1900, 2900, and 3900 Series Integrated Services Routers (ISR G2) are widely deployed in branch offices, enterprise networks, and distributed business environments. Models include the 1921 & 1941, 2901, 2911, 2921 & 2951, and 3925, 3945, 3925E & 3945E — spanning entry-level to high-performance branch routers supporting modular services, embedded security, and advanced WAN capabilities.

Unlike the newer ISR 4000 series with universal IOS XE images, ISR G2 routers use separate IOS feature sets activated by software licenses. The base IP Base image is included with the hardware. Additional technology packages — Security (SEC), High Security (HSEC), Data, Unified Communications (UC), and Application Experience (AppX) — unlock advanced networking, security, voice, and application optimization without replacing hardware.

This collection covers all ISR G2 license types across all three platform families. All licenses are genuine Cisco licenses delivered electronically via email within 24 hours.

Frequently Asked Questions

What license types are available for Cisco 1900, 2900, and 3900 routers?
Five license types are available: Security (SEC) for VPN/firewall/IPS, High Security (HSEC) to remove crypto throughput limits (2900/3900 only), Data for MPLS/BGP/advanced routing, Unified Communications (UC) for voice/CME/SRST (2900/3900 only), and AppX (APP) — an all-in-one bundle of DATA+UC+WAAS.
Which Cisco ISR G2 router models are supported?
All ISR G2 models across three platform families are supported: 1900 series (1921, 1941/1941W), 2900 series (2901, 2911, 2921, 2951), and 3900 series (3925, 3945, 3925E, 3945E). Each license SKU is series-specific — for example, L-SL-19-SEC-K9 for 1900 series and L-SL-39-SEC-K9 for 3900 series.
How are ISR G2 licenses different from ISR 4000 licenses?
ISR G2 (1900/2900/3900) routers use separate IOS feature sets activated by software licenses, requiring different IOS images per feature package. ISR 4000 routers use a single universal IOS XE image with software-activated licenses. G2 licenses are platform-specific: L-SL-19-* for 1900, L-SL-29-* for 2900, L-SL-39-* for 3900 series.
How are Cisco ISR G2 licenses delivered after purchase?
All licenses are genuine Cisco license files delivered electronically via email within 24 hours. After purchase, run show license udi on your router, send us the output, and you'll receive the license file for instant CLI activation. Free installation support is included.
