Cisco 4000 Series Integrated Services Routers-Series Comparison

February 9 2015 , Written by Cisco & Cisco Router, Network Switch Published on #Cisco Routers

Cisco users may have a general impression on the Cisco 4000 family. We also talked about the main features of Cisco 4000 ISR routers and the ordering guide. So in this article we will discuss the main model comparison of Cisco 4000 series that contains five platforms: the Cisco 4451, 4431, 4351, 4331, and 4321 ISRs, which differ primarily in performance capabilities and in the number of Network Interface Module (NIM) and Enhanced Service Module (SM-X) slots supported. What’s the main difference between these models? You can check the main table of Cisco 4000 model comparison.
