When using the GBIC media, there is also the additional negotiation auto command that is used to enable the IEEE 802.1z Gigabit Ethernet (1000 Mbps) autonegotiation protocol.

Step 2 To turn the autonegotiation feature off (it is on by default), issue the interface command no negotiation auto. This is useful for connecting to other Gigabit Ethernet equipment that does not support 802.1z autonegotiation.

Note The autonegotiation feature is not supported when using the rj-45 media type and will be ignored if implementation is attempted

If you change from the GBIC or SFP to the RJ-45 media type, you must set speed and duplex after you have executed the media-typecommand to ensure the interface will operate in the correct mode.

The media-typeGBIC or media-type SFP mode will always default to 1000 Mbps. Both full-duplex and half-duplex operation are supported in this mode.

	The following shows a typical configuration for the three Gigabit Ethernet interfaces on the NPE-G1. In
	this example, the first interface is configured for the GBIC media type, the second interface is configured
	for the RJ-45 media type, and the third interface is not used.
	interface GigabitEthernet0/1
	ip address 10.198.75.35 255.255.255.240
	load-interval 30
	no keepalive
	duplex full
	speed 1000
	media-type gbic
	no negotiation auto
	no cdp enable
	no shutdown
	!
	interface GigabitEthernet0/2
	ip address 10.179.16.2 255.255.255.240
	duplex auto
	speed auto
	media-type rj45
	no cdp enable
	no shutdown
	!
	interface GigabitEthernet0/3
	no ip address
	shutdown
	duplex auto
	speed auto
	media-type rj45
	no negotiation auto
	no cdp enable

Note	At the very minimum, an interface must be configured with the ip address, media-type, and speed
	commands before it can be enabled using the no shutdown command. Other interface commands might
	be needed, depending on the nature of the connected network.

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.
