Cisco 8100 Series Routers
The Cisco 8100 Series Routers utilizes Cisco’s new Router-on-Chip (RoC) model to deliver full routing
functionality with a single ASIC per router. The RoC architecture is distinguished from System-on-Chip (SoC)
switches by supporting large forwarding tables, deep buffers, more flexible packet operations, and enhanced
programmability.
The Cisco 8100 series routers include the following variants:
• Cisco 8102-64H - It provides 6.4 Tbps of network bandwidth with dramatically lower power consumption
than contemporary 10 Tbps systems. The Cisco 8102 Router is a fixed port, high density, two rack unit
form-factor router. Supported ports include 64 x 100G QSFP28.
• Cisco 8102-64H-O - It provides 6.4 Tbps of network bandwidth with dramatically lower power
consumption than contemporary 10 Tbps systems. The Cisco 8102 Router is a fixed port, high density,
two rack unit form-factor router. Supported ports include 64 x 100G QSFP28. The Cisco 8102-64H-O
supports the open-source network operating system SONiC (Software for Open Networking in the Cloud).
• Cisco 8101-32FH - It provides 12.8Tbps of network bandwidth. The Cisco 8101-32FH Router is a fixed
port, high density, one rack unit form-factor router. Supported ports include 32 x 400G QSFP-DD. The
functionality and installation of this router is similar to that of Cisco 8201-32FH. The Hardware Installation
Guide for Cisco 8201-32FH is available here.
