C9300-24UXB-M Full Official English Specification Description

1. SKU Definition

• UX: Multi-Gigabit Smart Rate auto-sensing RJ45 ports + Cisco UPOE, maximum 60W per port via LLDP power negotiation
• B: Higher Scale Deep Buffer hardware upgrade, 32MB on-chip packet buffer plus expanded MAC/IPv4/IPv6/ACL routing table capacity versus standard UX for high-burst multicast, IP surveillance and dense Wi-Fi 6/6E AP deployments
• -M: Meraki Cloud Managed platform; managed exclusively via Meraki Dashboard, subscription term licensing (Enterprise/Advanced tier, 1/3/5/7/10-year contracts) rather than traditional Cisco perpetual Network licenses; hybrid IOS XE + Meraki cloud orchestration firmware

2. Product Overview

Port & PoE Hardware Specifications

• 24×Multi-Gigabit mGig RJ45 downlinks auto-negotiate 100Mbps/1G/2.5G/5G/10GBASE-T; every port complies with IEEE802.3af/at PoE+ plus Cisco proprietary UPOE delivering up to 60W single-port power output
• Factory preinstalled single PWR-C1-1100WAC AC modular PSU; baseline PoE power budget = 560W. Optional redundant secondary 1100WAC PSU raises total PoE budget up to 1440W; Cisco StackPower enables cross-stack power pooling to allocate full UPOE 60W to all ports across stacked chassis
• Single rear modular uplink expansion slot compatible with official C9300 uplink network modules: C9300-NM-4G (4×1G SFP), C9300-NM-4M (4×10G SFP+), C9300-NM-2Q (2×40G QSFP+), C9300-NM-8X (8×10G SFP+), flexible uplink bandwidth ranging from 1Gbps up to 40Gbps

Core Higher-Scale Hardware Performance (UXB Exclusive Specs)

• Standalone switching fabric capacity: 640 Gbps; aggregated stacking throughput up to 1120 Gbps
• Wire-rate IPv4/IPv6 forwarding rate: 476.19 Mpps; maximum stacked aggregate forwarding up to 833.33 Mpps
• Stacking: Cisco StackWise-480 with 480Gbps per-stack bandwidth; maximum 8 same-series C9300-M switches stack into one unified logical switch via dedicated stacking cables
• System hardware: 8GB DRAM +16GB onboard flash storage, three hot-swappable variable-speed redundant cooling fans; embedded Catalyst 9800 onboard wireless controller centrally manages up to 200 Cisco enterprise wireless APs
• UXB Higher-Scale Table Capability:
  • MAC address table: 64,000 entries (double standard UX’s 32,000 entries)
  • IPv4 routing table:64,000 entries; IPv6 routing table:32,000 entries; Multicast route table:16,000 entries
  • ACL/QoS table capacity:18,000 entries; Jumbo frame support up to 9198 Bytes
• Packet Buffer:32MB deep buffer (standard UX =16MB), designed to minimize packet loss under congested burst traffic and heavy multicast streaming

3. Meraki Subscription License Tier (-M Core Feature Split, No Perpetual License)

Tier 1: Meraki Enterprise Subscription (Base Licensed Functions)

1. Complete Layer2 switching suite: 802.1Q VLAN, STP/RSTP/MSTP, LACP port-channel, port security, DHCP Snooping, DAI, 802.1X/MAB wired authentication, broadcast storm control, EEE Energy Efficient Ethernet
2. Basic Layer3 routing: Static routing + RIP protocol only; limited VLAN inter-routing
3. Standard QoS marking, ingress policing, CoS/DSCP mapping, basic traffic monitoring via Meraki cloud dashboard, SNMP, centralized syslog & real-time port statistics
4. Native Meraki cloud features: Zero-Touch Provisioning(ZTP), bulk firmware upgrade, remote cable diagnostics, unified network topology visualization, cross-site configuration template replication

Tier 2: Meraki Advanced Subscription (Optional Upgraded Paid License)

Remark: Meraki license is organization-bound; co-term deployment requires all stack switches to deploy identical license tier (all Enterprise or all Advanced) in most licensing models.

4. Physical & Environmental Specifications

• Global compliance certification: UL60950-1, CE, FCC Class A, RoHS & WEEE compliant; covered under Cisco Limited Lifetime Hardware Warranty (hardware warranty unaffected by Meraki license expiry)

5. Suffix Abbreviation Summary

• UX = Multi-Gigabit 100M~10G auto-negotiate RJ45 + per-port max 60W Cisco UPOE
• B = Higher Scale Deep Buffer hardware (32MB packet buffer, expanded MAC/route/ACL table for heavy burst & multicast traffic)
• -M = Meraki Cloud-Managed model, subscription-based Enterprise/Advanced licensing, centralized Meraki Dashboard orchestration instead of traditional perpetual Network Advantage/Essentials permanent license
