Node Switch Processor

The Cisco 6400 NSP provides ATM switching functionality. The NSP uses permanent virtual circuits

(PVCs) or permanent virtual paths (PVP) to direct ATM cells between the NRP and ATM interface. The

NSP also controls and monitors the Cisco 6400 system, including component NLCs and NRPs.

Node Route Processor

The Cisco 6400 supports three node route processors, designated as NRP-1, NRP-2, and NRP-2SV (see

Table1-1 for major differences):

• NRP-1—Incorporates a 100-Mbps Fast Ethernet interface for connecting into an IP network and has

processing capability for OC-3 rate of user traffic.

• NRP-2 and NRP-2SV —Provides a Gigabit Ethernet interface and sufficient processing capability

for handling OC-12 rate of user traffic.
