The Cisco 1921 Integrated Services Router (ISR) is a compact, high-performance edge device designed for small to mid-size branch offices that demand enterprise-grade security, flexible connectivity, and scalable services. Building on the proven Cisco 1841 ISR platform, the 1921 delivers a robust foundation for data, voice, and security services within a single, reliable platform. It features embedded hardware encryption acceleration to offload cryptographic tasks from the main processor, ensuring secure, high-speed VPNs and encrypted data paths without compromising performance. The 1921 also offers optional firewall, intrusion prevention system (IPS), and advanced security services that empower organizations to enforce strict network policies at the network edge, protecting against evolving threats while maintaining agility in a dynamic business environment.

  • Secure, accelerated encryption: Embedded hardware encryption acceleration speeds up VPNs and encrypted traffic, reducing CPU load and delivering faster, more secure site-to-site and remote-access connections.
  • Optional security stack: Choose firewall, intrusion prevention, and additional security services to harden the network perimeter without adding complexity or trade-offs in performance.
  • Modular, scalable design: The Cisco 1921 supports flexible WAN connectivity and expansion through service modules, enabling you to scale throughput and features as your network grows.
  • Enterprise-grade management: Cisco IOS Software provides familiar administration, robust policy control, and seamless integration with Cisco security architectures and management tools.
  • Ideal for branch offices: A compact form factor, energy efficiency, and reliable operation make it a dependable gateway for voice, data, and security services at the edge.

Technical Details of Cisco 1921 Integrated Services Router

Technical details for the Cisco 1921 ISR are sourced from the specifications section of the product catalog on Synnex using the UPC or SKU as reference. Because configurations vary by model and licenses, exact figures such as aggregate routing throughput, VPN throughput, memory size, interface mix, and expansion options will differ. The following categories summarize the key specifications you can expect to find in the official spec sheets and catalog entries:

  • Throughput and performance: Aggregate and VPN throughput capabilities, including the impact of hardware encryption acceleration on overall performance.
  • Interfaces and expansion: Built-in Ethernet and serial interfaces with slots or slots-based modules for additional WAN/LAN connectivity and services.
  • Security features: Hardware-accelerated encryption, optional firewall, IPS, and other advanced security services integrated with Cisco IOS.
  • Management and software: Cisco IOS Software with CLI, Cisco Configuration Professional, and support for monitoring, logging, SNMP, NetFlow, and secure remote management.
  • Power, reliability, and environment: Power requirements, temperature ranges, and reliability features appropriate for branch office deployments.

Because the Cisco 1921 ISR lineup includes various configurations and licensing options, customers should consult the Synnex catalog entry for UPC/SKU details to obtain precise values for throughput, memory, interface counts, and supported service modules. In practice, you can expect a device designed to balance performance with a broad feature set, enabling secure, scalable service delivery at edge sites while maintaining investment protection through modular growth pathways.

How to install Cisco 1921 Integrated Services Router

  • Plan your deployment by selecting the appropriate WAN interfaces, security features, and license options that align with your branch office needs and growth projections.
  • Unbox, place the router in a secure, well-ventilated location, connect power, and establish initial console access using the RJ-45 console port (or USB console, if available) to begin configuration.
  • Power on the device and access the Cisco IOS CLI or a graphical management tool such as Cisco Configuration Professional for the initial setup. Configure device naming, administrator credentials, and management access controls before enabling services.
  • Enable and configure required services, including routing protocols, VPNs, firewall rules, IPS settings if desired, and QoS policies to prioritize voice and time-sensitive data.
  • Apply software updates and licenses as needed, save the configuration, and validate connectivity and security posture with test traffic, monitoring tools, and baseline security checks to ensure a proper, repeatable deployment.

Good for a dog who likes to chew
Size: Small, Color: Black
I bought this for our 7mo puppy. She loves to fetch the ball and chew on the tabs. The tabs are sturdy if you have a dog who loves to chew. Perfect size for our girl. It is a great for when she has pent up energy. It's below zero where we are so finding an indoor game is essential.

Heavy chewer approved.
Style: Ball, Size: Medium (Pack of 1)
My pomsky will destroy a toy in minutes. Ropes, and the "indestructible" nylon type stuffs are no match for my furry shark. This ball has stood up to him like David. He loves the crunch and it is so much more tolerable than a squeaker. These will be a staple in his toy box - Chuckit toys are really the most durable dog toys I have found in three years.

Dogs love them
Style: Ball, Size: Medium (Pack of 2)
Our dogs love these. What’s great is that you can add more plastic (like from water bottles) if the plastic starts to fall out from the center. If you have a chewer, though, these won’t last you long. Our shepherd mix loves these and then starts to pull the rubber apart the more she plays with it. Our other dogs treat it normally, though, and those ones last forever. They also get some decent height when bounced, and they make a unique whistling noise when thrown.
