• This step is usually preformed once.

 

 

 

• For router access, users need the Telnet server IP address and port

 

 

 

number for each RSP they access.

router.

 

 

 

 

• During the initial router setup, communicate with the router only

 

 

 

through the Console port of the primary RSP.

 

 

 

• The router Console port uses a serial cable connection to a terminal or

 

 

 

terminal server.

 

 

 

• The terminal settings are:

 

 

 

– Bits per second: 115200

 

 

 

–

Data bits: 8

 

 

 

–

Parity: None

 

 

 

–

Stop bit: 1

 

 

 

–

Flow control: None

 

 

 

• For information on the cable requirements for the Console port, see

section on page viii.

Step 3

 

 

Power on the router.

Starts the router.

 

 

 

• This step is required only if the router power is not on.

 

 

 

• For information on power installation and controls, see hardware

 

 

 

documentation listed in the “Related Documents” section on page viii.

Step 4

 

 

Identify the target RSP.

Identifies the RSP to which you connect in the next step.

 

 

 

• The Cisco ASR 9000 Series router has two RSPs: RSP0 and RSP1.

 

 

 

One is the active RSP, and the other is the standby.

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.
