The Cisco ISR4331-K9 is a high-performance, modular Integrated Services Router (ISR) designed for mid-sized enterprise branch offices and small campus WAN aggregation. As part of the Cisco 4000 Series, it converges advanced routing, security, voice, and application services onto a single 1RU platform. Powered by Cisco IOS XE and a multi-core CPU, it delivers scalable throughput and extensive modular flexibility for modern software-defined WAN (SD-WAN) and hybrid cloud environments.
Multi-Core Architecture: Dedicated 8-core CPU for control, data, and services planes, ensuring wire-speed performance even under heavy service loads.
Throughput Range: 100 Mbps (default) / 300 Mbps (with Performance License) / 2 Gbps (with Boost License).
High Memory: 4 GB DRAM (default), upgradable to 16 GB; 4 GB Flash (default), upgradable to 16 GB for large routing tables and feature support.
Onboard Ports:
3 x Gigabit Ethernet (GbE) ports: 1 x Combo (RJ-45/SFP), 1 x RJ-45, 1 x SFP.
Expansion Slots:
2 x NIM (Network Interface Module) slots: Supports T1/E1, ADSL/VDSL, 3G/4G LTE, and 1/10G Ethernet modules.
1 x SM-X (Enhanced Service Module) slot: For high-density switching, UCS E-Series servers, or WAN optimization.
1 x ISC (Integrated Services Card) slot: For additional security or voice modules.
Advanced Security: Integrated IOS Firewall, IPS, VPN (IPsec/SSL), and MACsec encryption for secure branch connectivity.
Cisco TrustSec: Supports security group segmentation and policy enforcement.
SD-WAN Ready: Full support for Cisco DNA SD-WAN (IWAN) for intelligent path control, application optimization, and secure cloud connectivity.
Voice Capable: Supports PVDM4 DSP modules for IP telephony, conferencing, and video transcoding.
Application Visibility: NBAR2, QoS, and EasyQoS for prioritizing business-critical applications.
Energy-Efficient: 1RU form-factor with smart cooling and low power consumption (typical 42W).
