Cisco NCS 5700 Router Overview
The Cisco NCS 5700 series fixed-port routers provide aggregation, distributed core, and peering fabric.
The Cisco NCS 5700 series offers two types of systems. Those without external-TCAM (non-SE) rely only
on the on-chip resources available for feature scale. The second type of system is equipped with external-TCAM
(-SE) which provides an extended scale in addition to the on-chip scale. These systems provide functionality
vital to both Top of Rack (ToR) and modern spine-and-leaf architectures.
NCS-57B1
The NCS-57B1 routers provide a power-efficient package with 4.8 Terabits of 400GE/100GE optimized
forwarding capacity.
