8. License Differentiator: Network Essentials (-E) vs Network Advantage (-A)
The suffix -E (Network Essentials) is Cisco’s entry perpetual license tier for Catalyst 9300L switches, built for cost-sensitive basic PoE wired access deployments. Key limitations compared with top-tier -A Network Advantage:
-
Restricted dynamic routing scale and no advanced routing protocols such as BGP, full EIGRP or MPLS
-
Incompatible with SD-Access fabric, TrustSec segmentation and zero-trust group-based policy control
-
Disabled advanced threat analytics and full DNA Center end-to-end automation workflows
All switches within a single StackWise stack must run identical license tiers to guarantee full stacking interoperability and consistent feature operation.
