The Cisco L-SLASR903-M-I= is a software license designed for carrier-grade metro Ethernet and IP aggregation on Cisco ASR 903 Series Aggregation Services Routers. This metro to metro IP license activates advanced IP features on the ASR 903 platform, helping service providers and enterprise metro networks deliver scalable, resilient, and efficient Layer 3 services. With L-SLASR903-M-I=, operators can extend IP services across multiple metro sites, simplify routing policies, and improve traffic engineering without changing existing hardware. The license uses an Electronic Software Delivery (ESD / e-Delivery PAK) model, so you receive a Product Authorization Key (PAK) by email, enabling fast deployment in data centers and remote locations across Asia, Europe, Africa, and North America. As a per-device software feature license, it allows flexible capacity planning: you only license the routers that need metro IP capabilities, which is ideal for phased rollouts by distributors and system integrators. For small and medium integrators, L-SLASR903-M-I= helps standardize on a single ASR 903 hardware platform while unlocking higher service tiers through software. End users benefit from more stable routing, better use of existing links, and improved uptime for VPN, business internet, and backhaul services. Because it is tied to the Cisco ASR 903 Series, the license integrates smoothly with existing IOS XR or IOS XE workflows, central management tools, and common provisioning processes. The electronic PAK format streamlines license activation, reduces shipping time, and avoids physical media handling, which is especially useful for large regional deployments and urgent network upgrades.
