Command Mode

 

Description

 

 

 

administration

 

Administration configuration mode allows you to assign system resources to RSPs.

configuration mode

From administration EXEC mode, use the configure command to enter administration configuration

 

 

 

 

submode:

 

 

RP/0/RSP0/CPU0:router(admin)# configure

 

 

RP/0/RSP0/CPU0:router(admin-config)#

 

 

Global configuration

Global configuration mode is the starting point for RSP configuration. Commands entered in this

 

 

mode affect the RSP as a whole, rather than just one protocol or interface. Global configuration mode

 

 

is also used for entering configuration submodes to configure specific elements, such as interfaces

 

 

or protocols.

 

 

To enter global configuration mode, type the configure command at the EXEC command prompt:

 

 

RP/0/RSP0/CPU0:router# configure

 

 

RP/0/RSP0/CPU0:router(config)#

 

 

Note The system prompt changes to “router(config)” to indicate that the router is now in global

 

 

configuration mode.

 

 

 

Configuration

 

From the global configuration mode you can enter more specific command modes. These are

submodes

 

available based on your access privileges and include protocol-specific, platform-specific, and

 

 

feature-specific configuration modes.

 

 

In the following example, MPLS LDP configuration mode is entered from global configuration

 

 

mode. The prompt for MPLS LDP configuration submode appears as config-ldp. The following

 

 

command syntax is used for entering configuration MPLS LDP submode:

 

 

RP/0/RSP0/CPU0:router# configure

 

 

RP/0/RSP0/CPU0:router(config)# mpls ldp

 

 

RP/0/RSP0/CPU0:router(config-ldp)#

 

 

Note The availability of any particular mode depends on the router features and the access rights

 

 

of the individual user. For example, a configuration mode for configuring access servers is

 

 

not available on most routers.

 

 

Interface configuration

The interface configuration submode is used to select and configure a hardware interface. To enter

 

 

interface configuration mode from global configuration mode, use an interface command. An

 

 

interface configuration command always follows an interface global configuration command, which

 

 

defines the interface type.

 

 

RP/0/RSP0/CPU0:router(config)# interface tunnel-te 2

 

 

RP/0/RSP0/CPU0:router(config-if)#

 

 

Router configuration

The router configuration submode is used to select and configure a routing protocol, like OSPF, or

 

 

IS-IS. The following command syntax is used for entering router configuration submode: router

 

 

protocol [protocol_options]

 

 

Replace protocol with the keyword for the protocol you want to configure. Replace protocol_options

 

 

with any keywords and arguments required for that protocol.

 

 

RP/0/RSP0/CPU0:router(config)# router ospf 100

 

 

RP/0/RSP0/CPU0:router(config-ospf)#

A9KMOD80TR, A9K24X10GETR, ASR 9000 specifications

Cisco Systems has long been a leader in networking technology, providing cutting-edge solutions for service providers and enterprise organizations alike. Among their standout products is the Cisco ASR 9000 Series Aggregation Services Routers, notably the A9K24X10GETR and the A9KMOD80TR models. These routers are engineered to deliver unmatched performance, scalability, and versatility for networks that require high bandwidth and low latency.

The Cisco ASR 9000 Series is built for the needs of today's complex service provider and enterprise networks. A significant feature of the A9K24X10GETR is its 24-port 10-Gigabit Ethernet module. This functionality allows for high-density connectivity, making it ideal for aggregating numerous connections to different parts of a network while maintaining optimal performance. Whether used for Internet service providers delivering high-speed connectivity or for enterprises looking to connect multiple branches, the A9K24X10GETR provides robust and reliable data transmission.

Further enhancing the capabilities of the ASR 9000 is the A9KMOD80TR module, which supports an extensive range of services. This module is designed to run a variety of technologies, including Layer 2 and Layer 3 services, MPLS (Multiprotocol Label Switching), and IPv6. Its ability to integrate seamlessly into existing infrastructures while providing the advanced features customers demand makes it an invaluable asset for network engineering teams.

Another cutting-edge technology present in the ASR 9000 Series is its support for eBGP (External Border Gateway Protocol), which plays a critical role in managing traffic across multiple networks. The routers are equipped with advanced telemetry features, empowering operators with real-time insights into network performance and health. Additionally, they come with integrated security features that protect against DDoS threats and other vulnerabilities.

In summary, Cisco's ASR 9000 Series, particularly the A9K24X10GETR and A9KMOD80TR, combines high-density connections, extensive service support, and advanced security and telemetry capabilities. These routers are perfect for demanding environments where reliable performance and adaptability are crucial. With their focus on innovation and performance, Cisco continues to shape the future of networking technology.
