2. Product Overview

Cisco Catalyst C9300X-24HXB-M is a 1U rack-mount Layer 3 stackable enterprise access switch running Cisco IOS XE optimized for high-density Wi-Fi deployment, smart building automation and IP surveillance access networking. It combines robust Catalyst 9300X switching hardware with Meraki zero-touch cloud orchestration; StackWise-1T high-speed stacking and StackPower+ cross-chassis power pooling are native onboard. The -B bulk variant is pre-configured with unified factory default settings for large-scale bulk project rollout to reduce on-site configuration workload.

Port & UPOE+ Power Specifications

24×Multi-Gigabit copper downlink ports auto-ranging from 100Mbps up to 10Gbps; every port fully supports 90W IEEE802.3bt UPOE+ power outputCisco
Preinstalled factory single PWR-C1-1100WAC universal AC PSU; baseline available PoE budget =735W. Optional hot-swappable redundant second 1100WAC PSU raises total PoE budget to 1590W; StackPower+ enables cross-stack power resource sharing across stacked devices to allocate full 90W UPOE+ to high-power endpointsCisco
Single rear modular uplink expansion slot supporting official C9300X dedicated uplink modules: C9300X-NM-8X(8×10G SFP+), C9300X-NM-4Y(4×25G SFP28), C9300X-NM-2Q(2×40G QSFP+), C9300X-NM-1C(1×100G QSFP28), flexible uplink bandwidth coverage from 1Gbps to 100Gbps

Core Hardware Performance Parameters

Standalone switching fabric capacity:880 Gbps; aggregated stacking throughput via StackWise-1T up to 1880 Gbps
Wire-rate standalone IPv4/IPv6 forwarding rate:654.76 Mpps; maximum full-stack aggregated forwarding throughput:1398.8 Mpps
Stacking architecture: StackWise-1T with 1000Gbps per-stack backplane bandwidth; maximum 8 identical C9300X-series switches can be stacked into one logical switching entity, supporting NSF/SSO sub-50ms non-stop forwarding failover protectionCisco Meraki
Core system hardware: Quad-core x86 processor, 16GB DRAM +16GB onboard flash storage, three variable-speed hot-swappable cooling fans; embedded onboard Catalyst 9800 wireless controller supports centralized management of up to 200 Cisco enterprise wireless access points
Forwarding table scale: MAC address table:96,000 entries; IPv4 route table:96,000 entries; IPv6 route table:48,000 entries; Multicast route table:24,000 entries; TCAM ACL/QoS table:24,000 entries; Jumbo frame support up to 9198 Bytes; 48MB deep packet buffer for burst multicast and high-concurrency user traffic

3. Meraki Cloud-Managed (-M) Feature Set (License Subscription Dependent)

All switch functions are unlocked via valid Meraki Enterprise or Advanced term subscription license (1/3/5/7/10-year optional term); no perpetual Network Advantage/Essentials permanent license preloaded on hardware, cloud subscription governs all feature entitlements.

Full Layer 2 Features under Meraki Subscription

4094 VLAN, RSTP/MSTP, LACP port-channel aggregation, port security, DHCP Snooping, DAI Dynamic ARP Inspection, 802.1X/MAB/CWA wired authentication, broadcast storm suppression, EEE Energy Efficient Ethernet, full CoS/DSCP QoS mapping, mDNS gateway for BYOD service discovery.

Complete Layer 3 Routing Suite

Inter-VLAN SVI routing, static routing, RIP/RIPng, OSPF, EIGRP, BGP, IS-IS, VRRP/HSRP, full PIM-SM/SSM multicast routing, SD-Access EVPN/VXLAN ready deployment; Adaptive Policy SGT traffic segmentation natively supported via Meraki cloud dashboard configuration.

Premium Security & Analytics Functions

Hardware-based MACsec link encryption, ETA Encrypted Traffic Analytics, Flexible NetFlow/IPFIX telemetry, TrustSec SGT segmentation, advanced hardware ACL filtering, zero-trust access control, all configurable centrally from Meraki cloud portal.

Manageability Mode Exclusive for -M Variant

Primary management via Meraki cloud dashboard (zero-touch provisioning, centralized config, real-time telemetry, automated firmware upgrade); backup local access via CLI console, SNMPv3, HTTPS; RESTCONF/YANG/NETCONF API available for third-party orchestration; no local IOS-XE standalone license activation required.

Bulk (-B) Supplement Note: Factory unified preloaded baseline startup-config for large batch shipment; all hardware capability fully consistent with standard non-bulk C9300X-24HX-M, only pre-defined base configuration differs for bulk project rollout.
