Chapter 4 Observing System Startup and Performing a Basic Configuration

Using show Commands to Check the Installation

Loading configuration files or system images using remote copy protocol (rcp) or Trivial File Transfer Protocol (TFTP)

Reloading the operating system

Using show Commands to Check the Installation

Use show commands to identify the hardware installed in your router, to verify the operation status, to view interface configuration settings, and to troubleshoot your router configuration. The interfaces on the NPE-G1 or NPE-G2 are identified by their chassis slot number and interface port number (slot/port). The interfaces on your I/O controller are also identified by chassis slot number and interface port number (slot/port). The chassis slot number for the I/O controller is always slot0. Table 4-1lists the NPE-G, NPE-G2, and the I/O controller models, their corresponding interfaces, and the interface addressing syntax for each interface.

Fast Ethernet (MII)

Chassis slot—always 0

fastethernet 0/0

 

 

 

Interface port—0

 

 

 

 

 

 

1.Both optical and copper ports report the same syntax. For example, Gigabit Ethernet RJ-45 port 0/2 reports GigabitEthernet 0/2, as does Gigabit Ethernet GBIC port 0/2.

2.The Product Number C7200-I/O-FE does not specify MII because both an MII and an RJ-45 receptacle are included.

3.The I/O controller with the Product Number C7200-I/O-FE-MII has a single MII FastEthernet receptacle only. Although still supported by Cisco Systems, this I/O controller with a single MII receptacle is no longer an orderable product as of May 1998.

7200 VXR specifications

The Cisco Systems 7200 VXR Series is a robust and highly scalable modular router designed to meet the demands of service providers and enterprises seeking high-performance solutions for their network infrastructures. Launched as part of the Cisco 7200 series, the VXR (Virtual Extensible Routing) variant enhances capabilities while providing effective support for a wide range of applications, including Internet Protocol (IP) routing, Voice over IP (VoIP), and Virtual Private Network (VPN) configurations.

At the core of the 7200 VXR is its modular design, which enables network administrators to customize the router according to their specific needs. The router supports a variety of interface cards, processing engines, and power supply options, ensuring flexibility for diverse network environments. This modularity facilitates easy upgrades and expansions, making it ideal for growing enterprises and service providers looking to future-proof their networks.

One of the standout features of the Cisco 7200 VXR is its impressive routing performance. It can handle a high level of traffic with low latency, which is critical for bandwidth-intensive applications. The router supports a wide array of routing protocols, including Border Gateway Protocol (BGP), Open Shortest Path First (OSPF), and Integrated Intermediate System-to-Intermediate System (IS-IS), providing versatility for various network topologies.

The 7200 VXR also incorporates advanced features for enhanced security and reliability. With support for IPsec VPNs, it enables secure data transmission across untrusted networks. The router also includes features like Quality of Service (QoS) for prioritizing network traffic, ensuring critical applications receive the bandwidth they require even during peak loads.

In terms of scalability, the Cisco 7200 VXR can support hundreds of thousands of routes and MAC addresses, making it suitable for large metropolitan area networks (MANs) as well as enterprise backbone applications. It also provides the capability to support IPv4 and IPv6 networks, preparing organizations for a transition to next-generation internet protocols.

Additional characteristics of the Cisco 7200 VXR include enhanced manageability through the Cisco IOS software, which offers a comprehensive command-line interface and support for network management protocols. The router is also energy-efficient, with options for redundant power supplies that ensure continuous availability and minimal downtime in mission-critical applications.

Overall, the Cisco Systems 7200 VXR represents a powerful solution that combines performance, scalability, and security, making it an excellent choice for organizations looking to enhance their network capabilities in a rapidly evolving technological landscape.
