Product Overview

The Cisco ® 7304 Router is designed for the network edge where high-performance IP services are required to enable profitability, service differentiation, and business agility. It is widely positioned as a WAN aggregation router in enterprise and high-end customer-premises-equipment (CPE) deployments or as a low-end provider-edge router in service provider deployments (Figure 1).

Figure 1. Cisco 7304 NSE-150 Network Services Engine

The Cisco 7304 NSE-150 is the forwarding engine or route processor for the Cisco 7304; it uses Parallel Express Forwarding (PXF) technology to deliver hardware-accelerated network services with up to 3.5-Mpps forwarding rate; it also has an 800-MHz microprocessor CPU to support a rich feature set in Cisco IOS ® Software with high performance and scalability. With the four onboard Gigabit Ethernet ports, it also increases the overall port density of the platform and maximizes the value of customers' investments. Detailed features are described in Table 1.

Table 1. Features of Cisco 7304 NSE-150



Hardware-accelerated features with up to 3.5-Mpps forwarding rate

• Cisco Express Forwarding, Turbo ACL, NetFlow v8, Multiprotocol Label Switching (MPLS), MPLS VPN, Network Address Translation (NAT), generic routing encapsulation (GRE), quality of service (QoS), IP Multicast, etc.

High performance and scalability of control-plane features

• 800-MHz microprocessor that allows non-PXF accelerated features to run at 800 kpps
• Increased scalability of control-plane features with 2-Gb memory

Backward compatibility

• Provides investment protection through backward compatibility

Note: Products that reached end-of-sale status before Cisco IOS Software Release 12.2(31)SB2 will not be supported on the NSE-150.

Support for Cisco IOS Software

• Supports a wide range of IP and non-IP network services, including QoS, MPLS, IPv6, IP Multicast, etc.

High availability

• Provides optional redundant-processor support for the industry's most compact, fully redundant, high-availability solution, improving network resiliency, management, and costs

Four fixed onboard Gigabit Ethernet ports

• Maximizes LAN connectivity and performance without taking up slot capacity

2 GB of synchronous dynamic RAM (SDRAM)

• Offers more scalability on features: routing table, Forwarding Information Base (FIB) table, IPv6 features, etc.


• Enables maximum investment protection and flexibility by allowing customers to upgrade to the NSE-150 network services engine or future Cisco 7304 processors

Dedicated management for 10-/100-Mbps Ethernet

Reduces costs and protects port density of the chassis

Two USB ports

Provides a large, removable storage for files (not enabled at first-customer-shipment [FCS] time, and the support will be available in future releases)

Digital diagnostics on Small Form-Factor Pluggable (SFP) interface

• Provides a powerful tool that monitors many manageable parameters, including optical transmit and receive power, voltage and temperature measurement, and factory parameters

Mean time between failure (MTBF)

• 89,718 hours

New Features

With the introduction of the Cisco NSE-150, the following is offered (refer to Table 1 for details):

• Improved processing power for the control-plane functions (for example, routing protocols and statistics collection)

• Improved processing power for route processor-processed data traffic (for example, traditional protocol traffic such as X.25)

• Increased route-processor and PXF memory to enable more scalability (routing table, FIB table, etc.)

• Additional port density through onboard Gigabit Ethernet ports (two more onboard Gigabit Ethernet ports compared to NSE-100)

• USB interfaces to provide a large removable file storage

• Support for up to 16,000 IDBs, whereas NSE-100 supports 4,000 IDBs and NPE-G100 supports 8,000 IDBs

Upgrade Paths

The Cisco 7304 NSE-150 is part of the Cisco Technology Migration Program (TMP). Customers are encouraged to review their networking requirements and to use the TMP to upgrade from previous generations of Cisco 7304 Series network processing engines to the Cisco 7304 NSE-150. Refer to and contact your local Cisco account representative related to the TMP.


The Cisco 7304 Series NSE-150 is available and supported as of Cisco IOS Software Special Release 12.2(31)SB2.
The Cisco 7304 Series NSE-150 is supported in the Cisco 7304 chassis.
