1921 ISR Specs


Sticker price is a little higher on the 1921 series integrated routers compared to competitors. However, companies who invest in a Cisco router will immediately begin to see ROI due to the increased efficiency and security inherent in these products.

Companies find solace in Cisco’s years of experience and router testing, usually finding that an investment now guarantees reliable years of performance ahead.

Cisco also provides investment protection because IT can:

  • Reuse several existing modules supported on the original ISRs.
  • Enjoy Cisco IOS Software features that are carried forward from original routers and delivered in the Universal image.
  • Flexibly configure network as business evolves and grows.


1921 series routers include access to Cisco’s IOS software Security tech package, which offers admins increased visibility, granting advanced threat detection and protection.

Companies with collaborative communications enjoy the 1921 series’ enhanced protection features like group-encrypted transport VPN, dynamic multipoint VPN (DMVPN)  and easy VPN (EzVPN).


With a single Cisco IOS Software Universal image, businesses can quickly deploy added features without having to download a new image, and companies can deploy a 1900 series router in a high-speed WAN environment with concurrent services enabled up to 15 Mbps.


Great for companies with smaller IT budgets that expect future growth, the 1921 is scalable as needed, allowing IT to add new interfaces as needed.

A large default memory supports new capabilities, and routers’ modular architecture offers optimal performance as companies grow. The modular interfaces also offer increased bandwidth, diverse connection options and network resiliency.


With 3G wireless WAN access, the 1900 series ISRs combine traditional enterprise functions with mobile capabilities. Routers can replace or work with landline infrastructure like dial-up, Frame Relay and ISDN.

Cisco 1921 ISR Review

“Put one at each of our dealerships. they are connected via our ISP’s network running OSPF. We pump all of our dealerships’ traffic over them and they perform well and are very stable. We used them to replace unstable VPN gear. When we did use them as VPN routers they performed very well also. Cisco is my go to for network equipment.”
