NM-16ESW-1GIG Use Case
Branch Office LAN Consolidation with Integrated Switching and Gigabit Uplink
A mid-sized financial services branch deploys a Cisco ISR equipped with NM-16ESW-1GIG-1 to terminate 16 workstations, IP phones, and networked printers on 10/100Base-T ports, while leveraging the 1 GE (1000Base-T) uplink to the corporate data center over an MPLS WAN. This consolidation replaces standalone switches and routers, reducing hardware footprint by 40%, lowering power and rack-space requirements, and centralizing network management for faster provisioning and policy enforcement.
Retail Point-of-Sale Segmentation and PCI-Ready Network Architecture
A nationwide retail chain uses the NM-16ESW-1GIG-1 module in each store’s edge router to isolate POS terminals, inventory scanners, and back-office PCs into dedicated VLANs on its 16 10/100 ports. The single GE port uplinks encrypted traffic to the corporate HQ, ensuring separation of payment data and guest Wi-Fi. The result is simplified VLAN segmentation, compliance with PCI DSS requirements, and high-speed, secure backhaul without additional switching infrastructure.
Satellite Office VoIP and Video Conferencing Optimization
An international law firm outfits satellite offices with Cisco routers hosting the NM-16ESW-1GIG-1 module to connect IP phones, video endpoints, and PCs on 16 FastEthernet ports. QoS policies prioritize voice and video streams, while the gigabit uplink over SD-WAN ensures low latency to headquarters. Outcomes include crystal-clear voice/video quality, streamlined deployment of unified communications, and measurable reductions in call-setup times and jitter.

Questions & Answers
What is the Cisco NM-16ESW-1GIG network module?
The Cisco NM-16ESW-1GIG is a network module that provides 16 10/100 Ethernet switch ports and one 1 GE (1000Base-T) uplink port for compatible Cisco routers.
Which Cisco routers are compatible with the NM-16ESW-1GIG module?
The NM-16ESW-1GIG is compatible with Cisco 2800, 2900, 3800 and 3900 Series Integrated Services Routers that feature an NM slot.
How do I install the Cisco NM-16ESW-1GIG in my router?
Power off the router, slide the NM-16ESW-1GIG into an available NM slot until it clicks, secure the captive screws, then power on and verify with the show module command.
How do I configure the 16 switch ports on the NM-16ESW-1GIG?
Enter global configuration mode, select the interface range (e.g., interface range fastEthernet 0/1-16), then apply VLAN, speed, duplex, or spanning-tree settings as needed.
Does the NM-16ESW-1GIG support advanced Layer 2 features?
Yes, it supports VLANs, port security, STP/RSTP/MSTP, QoS, IGMP snooping, and dynamic MAC address learning at wire speed.
What is the maximum switching capacity of the NM-16ESW-1GIG?
The module delivers up to 10 Gbps of full-duplex switching bandwidth across its 16 10/100 ports and 1 GE uplink port.
Can I stack or cascade multiple NM-16ESW-1GIG modules?
No, the module is designed for a single NM slot per router; for higher port density, use a larger Cisco switch or additional router slots.
