Cisco Catalyst C9300LM-24T-4G-A, 1RU stackable Meraki cloud-managed Layer3 non-PoE Gigabit access switch, 24-port 10/100/1000BASE-T RJ45 data-only downlinks, 4 fixed 1G SFP uplink interfaces, StackWise-320 stacking support, factory pre-installed 350W AC power supply, single-pane Meraki Dashboard cloud management for multi-site office, classroom and branch wired networks with PCs, printers and servers requiring 1G fiber aggregation uplinks.

3. Complete Product Overview Paragraph

The Cisco Catalyst C9300LM-24T-4G-A is a compact data-only fixed-uplink stackable Layer 3 edge switch within the Catalyst 9300LM Meraki cloud-managed portfolio, designed for corporate offices, K-12 education classrooms, small branch server closets and desktop workgroup deployments with zero PoE-powered endpoints. Equipped with 24 standard non-PoE Gigabit copper RJ45 downlink ports and four onboard 1G SFP fiber uplink ports, this chassis shares identical Layer 2/Layer 3 hardware forwarding performance with on-prem IOS XE C9300L-24T switches, yet all configuration, firmware upgrades, real-time monitoring, alerting and security policy management are centralized exclusively via the Meraki cloud dashboard. It supports StackWise-320 stacking technology to aggregate up to 8 identical C9300LM switches into a single unified logical switching stack, features dual hot-swappable 350W AC power supply bays for power redundancy, and delivers native cross-device unified policy orchestration alongside Meraki MR wireless access points and MX security gateways in one cloud console. Meraki zero-touch provisioning (ZTP), remote cable diagnostics, cross-site topology mapping and Adaptive Policy zero-trust segmentation are core native functions exclusive to all C9300LM cloud-managed switches.

7. Meraki Cloud Native Layer 3, Security & Orchestration Features

Routing Capabilities (Controlled by Meraki Subscription Tier)

Static IPv4/IPv6 routing, RIP, OSPFv2/v3, VRRP gateway redundancy, wire-speed inter-VLAN routing, PIM sparse-mode stub multicast routing. Enterprise license enforces a 1,000 OSPF learned route limit; Advanced license removes OSPF route scale limitations.

Cloud-Managed Enterprise Security

IEEE 802.1X multi-domain/multi-host authentication, MAB MAC bypass authentication, DHCP snooping, Dynamic ARP Inspection (DAI), IP Source Guard, CoPP control-plane policing, hardware Secure Boot & Trust Anchor Module, granular RBAC multi-admin dashboard permissions, TLS/SSH encrypted communication between switch and Meraki cloud, end-to-end Adaptive Policy group-based traffic segmentation (requires Meraki Advanced subscription license).

Meraki Exclusive Cloud Automation & Visibility

Zero-touch provisioning (ZTP) out-of-box automatic registration to Meraki organization, global bulk firmware scheduling and staged upgrade deployment, live remote cable testing without on-site IT technicians, real-time cross-site network topology mapping, unified wired/wireless policy synchronization with Meraki MR access points and MX security gateways, centralized cloud-hosted event logging, full IPFIX traffic analytics, cross-device fault alerting via email/SMS notifications, on-demand remote packet capture for offline fault troubleshooting.

8. Meraki-M Subscription License Tier Differentiation

All C9300LM series switches require renewable term-based Meraki Catalyst subscription licenses (1/3/5/7/10-year terms), split into two functional tiers:

1. Enterprise License (Base Tier)
   Complete Layer 2 switching, limited OSPF route scale, standard edge security functions, cloud monitoring and ZTP automation; Adaptive Policy segmentation and Encrypted Traffic Analytics (ETA) are disabled.
2. Advanced License (Full Feature Tier)
   Unlimited dynamic routing table capacity, Adaptive Policy zero-trust security segmentation, Encrypted Traffic Analytics (ETA), full IPFIX flow telemetry, complete cross-domain wired-wireless fabric policy orchestration, 256-bit AES MACsec link encryption support.
   Key difference vs on-prem C9300L (-E/-A IOS XE models): C9300LM-M hardware relies on time-limited cloud subscription licensing, while C9300L uses permanent perpetual IOS XE licenses without mandatory cloud connectivity. All stack members must deploy matching Meraki license tiers to ensure full stacking interoperability and consistent feature operation.

9. Datasheet Short Summary Paragraph
