Disabling Debugging for All Services Started at All Terminal Sessions

Use the undebug all all-ttycommand to turn off debugging for all services that have been started from all terminal sessions. For example if you enter this command while connected to the router through the console port on the active RP, all debug sessions started from all ports are disabled. In the following example, debugging for all services and ports is disabled and then verified:

RP/0/0/CPU0:router# undebug all all-tty

RP/0/0/CPU0:router# show debug

No matching debug flags set

Configuration Error Messages

The following sections contain information on configuration error messages:

•Configuration Failures During a Commit Operation, page 6-6

•!Configuration Errors at Startup, page 6-7

Configuration Failures During a Commit Operation

A target configuration is added to the running configuration of a router when the commit command is entered. During this operation, the changes are automatically verified by the other components in the system. If successful, the configuration becomes part of the running configuration. If some configuration items fail, an error message is returned.

To display the configuration items that failed and see the cause of each failure, type the show configuration failed command.

Note The show configuration failed command can be entered in either the EXEC mode or any configuration mode. In any mode, the configuration failures from the most recent commit operation are displayed.

In the following example, a configuration error occurs when an invalid commit operation is attempted:

RP/0/RP0/CPU0:router# configure

RP/0/RP0/CPU0:router(config)# taskgroup alr

RP/0/RP0/CPU0:router(config-tg)# description this is an example of an invalid task group

RP/0/RP0/CPU0:router(config-tg)# commit

%Failed to commit one or more configuration items. Please use 'show configuration failed' to view the errors

!To display the configuration items that failed, including a description of the error, type the

show configuration failed command:

P/0/RSP0/CPU0:router(config-tg)# show configuration failed

!! CONFIGURATION FAILED DUE TO SEMANTIC ERRORS

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.
