Configuring the RSP Hostname

Chapter 3 Configuring General Router Features

Managing Configuration Sessions

F I N A L D R A F T — C i s c o C o n f i d e n t i a l

If you end a configuration session without committing the configuration changes, the router prompts you to save changes, discard changes, or cancel the action, as shown in the following example:

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

Uncommitted changes found, commit them before exiting(yes/no/cancel)? [cancel]:

Respond to the prompt by entering one of the following options:

•yes—Commit the configuration changes and exit configuration mode.

•no—Exit configuration mode without committing the configuration changes.

•cancel—Remain in configuration mode without committing the configuration changes.

Note In EXEC mode, the exit command logs the user out of the system.

Aborting a Configuration Session

When you abort a configuration session, any changes are discarded and the configuration session ends. No warning is given before the configuration changes are deleted.

In global configuration mode, the abort command discards configuration changes and returns to EXEC mode. In administration configuration mode, the abort command discards configuration changes and returns to administration EXEC mode. To abort a configuration session, type the abort command, as shown in the following example:

RP/0/RSP0/CPU0:router# configure

RP/0/RSP0/CPU0:router(config)# hostname host1

RP/0/RSP0/CPU0:router(config)# interface Gi 0/2/0/2

RP/0/RSP0/CPU0:router(config-if)# description this is my interface

RP/0/RSP0/CPU0:router(config-if)# ipv4 address 10.1.1.1 255.0.0.0

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

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

RP/0/RSP0/CPU0:router#

The hostname identifies an RSP on the network. Although devices can be uniquely identified by their Layer 2 and Layer 3 addresses (such as an IP address), it is often simpler to remember network devices by an alphanumeric “hostname.” This name is used in the CLI prompt and default configuration filenames and to identify the RSP on the network.

To configure the hostname, type the hostname command with the RSP name as shown in the following example:

RP/0/RSP0/CPU0:router# configure

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

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

RP/0/RSP0/CPU0:Apr 7 00:07:33.246 : config[65669]: %LIBTARCFG-6-COMMIT : Configuration committed by user 'user_a'. Use 'show configuration commit changes 1000000067' to view the changes.

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

The preceding example sets the RSP name to RP_SJ.

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.
