Cisco 1921 vs. cisco 1941 vs. cisco 2901

  1. 1. Cisco 1921 vs. Cisco 1941 vs. Cisco 2901 If you wanna buy a Cisco router to set up your network, maybe you are confused with the detailed functions of these models, such as Cisco 1921, Cisco 1941 and Cisco 2901. Which one would be better for your network setup? For example, if you need one that support over 10 routing protocol such as OSPF, BGP, EIGRP, PIM-SM, IGMPv3, static IPv4 routing, static IPv6 routing; an evolutionary platform with multicore CPUs, etc. the CISCO1941W-E/K9 may be not a bad choice. So what are the main differences between the following routers: Cisco 2901, Cisco 1941 and Cisco 1921? Here we list the main differences and features of Cisco 1921, CISCO 1941 and Cisco 2901 in the following table: Cisco 1921, Cisco 1941 and Cisco 2901 Comparison CISCO 1921 Cisco 1941/Cisco 1941W Cisco 2901 Form Factor 1 RU 2 RU 1 RU Integrated WAN Ports 2 Gigabit Ethernet 2 Gigabit Ethernet 2 Gigabit Ethernet Interface slots (enhanced high-speed WAN interface card [EHWIC]) 2 2 4 Interface Slots, Network Interface Modules N/A N/A N/A Service-module slots 0 0 0 Integrated services module (ISM) slots 0 1 1 Packet-voice data-module (PVDM) slots 0 0 2 USB Ports (v2.0) 1 2 2 Default/maximum flash memory 256 MB/256 MB 256 MB/ 8 GB 256 MB/ 8 GB
