4-Port Multi-Gigabit Cisco Module 1G/2.5G/5G/10G Adaptive SD-Access & MACsec Support For Catalyst 9300
 

The Cisco C9300-NM-4M= is a high-performance 4-port Multi-Gigabit Ethernet expansion module designed for Catalyst 9300 Series switches, enabling flexible bandwidth scaling for enterprise networks. It combines multi-rate adaptability (1G/2.5G/5G/10G), SD-Access automation, and hardware-based MACsec encryption to support modern IoT, Wi-Fi 6, and high-density workloads.

Key Features & Benefits

1. Multi-Gigabit Flexibility

   • 4x 10GBASE-T ports with auto-negotiation for 1G/2.5G/5G/10G speeds, ideal for mixed-device environments (e.g., legacy IP phones + Wi-Fi 6E access points).

   • Line-rate throughput with non-blocking architecture for latency-sensitive applications (VoIP, video).

2. Enterprise-Grade Security

   • MACsec (IEEE 802.1AE) encryption for hardware-level data confidentiality on all ports.

   • Cisco TrustSec support for policy-based segmentation and compliance.

3. Software-Defined Ready

   • Cisco SD-Access compatibility for automated provisioning and zero-trust networking.

   • Programmable with APIs (Python, Ansible) for DevOps integration.

4. Simplified Scalability

   • Hot-swappable design for seamless upgrades without downtime.

   • Unified management via Cisco DNA Center.
