The NPUI-20 consists of the following planes:
l
Control and management plane
Through the management channels between MPUs and NPUI-20s, the MPUs can manage
NPUs and associated subcards, and transmit routing protocol data.
l
Data forwarding plane
The NPUI-20s are responsible for service processing in the entire system, and are connected
to all subcards through data channels.
An NPUI-20 provides two 10G Ethernet optical interfaces that can work in the WAN or
LAN mode and can be installed with XFP optical modules.
