Simple Administration Configuration Session: Example

The following example shows a simple administration configuration session in which the target configuration is created and previewed in administration configuration mode:

RP/0/RSP0/CPU0:router# admin

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

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

RP/0/RSP0/CPU0:router(admin-config-sdr:test)# location 0/1/SP

RP/0/RSP0/CPU0:router(admin-config-sdr:test)# show configuration

Building configuration...

sdr test location 0/1/SP

!

end

Starting an Exclusive Configuration Session

An exclusive configuration session allows you to configure the administration configuration or an RSP and lock out all users from committing configuration changes until you are done. Other users can still create and modify a target configuration, but they cannot commit those changes to the running configuration until you exit.

During regular configuration sessions, the running configuration is locked whenever a commit operation is being performed. This automatic locking ensures each commit operation is completed before the next one begins. Other users receive an error message if they attempt to commit a target configuration while another commit operation is under way.

To start an exclusive configuration session for an RSP, connect to that RSP and type the configure exclusive command:

RP/0/RSP0/CPU0:router# configure exclusive

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

Note If the configuration is already locked by another user, the configure exclusive command fails. To view locked and unlocked configuration sessions, see the “Viewing Active Configuration Sessions” section on page 3-19.

To start an exclusive configuration session for the administration configuration, connect to the RSP and type the configure exclusive command in administration EXEC mode:

RP/0/RSP0/CPU0:router# admin

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

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

The running configuration is unlocked when the user who started the exclusive configuration session exits the configuration mode, as described in the “Ending a Configuration Session” section on page 3-31.

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.
