Input/Output Controller

This section describes five different models of I/O controllers. These models are distinguished from one another by their Ethernet interface options. Table 1-22lists the I/O controllers by product number and describes their differences.

Note For a description of the configuration commands you need to configure the different interfaces on your I/O controller, refer to the Input/Output Controller Replacement Instructions document.

I/O Controller Descriptions

 

 

Product Number

Description

 

 

C7200-I/O-GE+E

1 Gigabit Ethernet and 1 Ethernet port; equipped with a GBIC receptacle for

 

 

1000 megabits per second (Mbps) operation and an RJ-45 receptacle for

 

 

10-Mbps operation. (See Figure 1-15.)

 

 

C7200-I/O-2FE/E

2 autosensing Ethernet/Fast Ethernet ports; equipped with 2 RJ-45 receptacles

 

 

for 10/100-Mbps operation. (See Figure 1-16.)

 

 

 

C7200-I/O-FE1

 

1 Fast Ethernet port; equipped with an MII receptacle and an RJ-45receptacle

 

 

for use at 100 Mbps full-duplex or half-duplex operation. Only 1 receptacle

 

 

can be configured for use at a time. (See Figure 1-17and Figure 1-18 .)

 

 

 

C7200-I/O

 

Has no Fast Ethernet port. (See Figure 1-19and Figure 1-20.)

 

 

C7200-I/O-FE-MII2

1 Fast Ethernet port; equipped with a single MII receptacle. (See Figure 1-21.)

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

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

You can also identify your I/O controller model from a terminal by using the show diag slot 0 command. (See the “Viewing Your System Configuration” section on page 4-20.)

The I/O controllers consist of the following components and options:

•Ethernet, Fast Ethernet, or Gigabit Ethernet interface options

•Dual channels for local console and auxiliary ports

The console port has full data communications equipment (DCE) functionality and the auxiliary port has full data terminal equipment (DTE) functionality.

•NVRAM for storing the system configuration and environmental monitoring logs

Note NVRAM uses lithium batteries to maintain its contents when disconnected from power. Some I/O controllers use a static RAM (SRAM) component with an external lithium battery to provide the same functionality as the NVRAM.

•Two PC Card (PCMCIA) slots that hold Flash Disks or PC Cards for storing the default Cisco IOS software image

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.
