Command Mode

 

Description

 

 

 

Router submode

 

Router configuration submodes are accessed from router configuration mode. The following

configuration

 

command syntax is used for entering router address family configuration submode:

 

 

 

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

 

 

 

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

ROM Monitor

 

The ROM Monitor is a bootstrap program that initializes the hardware and boots the system when a

(ROMMON) mode

router is powered on or reset. ROM Monitor mode is also known as “ROMMON,” which reflects the

 

 

 

CLI prompt for the mode.

 

 

 

rommon B1>

 

 

 

During normal operation, users do not interact with ROMMON. This mode is accessed only by

 

 

 

manually interrupting the boot process and placing the system in ROMMON. Once in ROMMON,

 

 

 

you can perform ROM Monitor tasks, including reinstallation of the Cisco IOS XR Software,

 

 

 

password recovery, and other diagnostic tasks.

 

 

 

The ROM Monitor CLI mode is accessible only from a terminal connected directly to the Console

 

 

 

port of the primary RSP, a terminal-modem connection to the AUX port, or through a terminal server.

 

 

 

See Cisco ASR 9000 Series Aggregation Services Router ROM Monitor Guide for information and

 

 

 

instructions on using ROM Monitor mode.

 

 

 

 

Entering EXEC Commands from a Configuration Mode

EXEC commands can be executed from any configuration mode by preceding the command with the do keyword. Executing EXEC commands from a configuration mode allows you to view the state of the system without exiting the configuration mode. For example:

RP/0/RSP0/CPU0:router(config)# do show version

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.
