Adding a Filter at the --More-- Prompt

Note Filtering is available for submodes, complete commands, and anywhere that <cr> appears in the “?” output.

You can specify a filter at the --More--prompt of a show command output by entering a forward slash (/) followed by a regular expression. The filter remains active until the command output finishes or is interrupted (using Ctrl-Z or Ctrl-C). The following rules apply to this technique:

•If a filter is specified at the original command or previous --More--prompt, a second filter cannot be applied.

•The use of the keyword begin does not constitute a filter.

•The minus sign (–) preceding a regular expression displays output lines that do not contain the regular expression.

•The plus sign (+) preceding a regular expression displays output lines that contain the regular expression.

In the following example, the user adds a filter at the --More--prompt to show only the lines in the remaining output that contain the regular expression “ip.”

RP/0/RSP0/CPU0:router# show configuration running begin line

Building configuration...

line console exec-timeout 120 120

logging trap --More--

/ip filtering...

ip route 0.0.0.0 255.255.0.0 Gi0/2/0/0 interface Gi0/2/0/0

ip address 172.19.73.215 255.255.0.0 end

Tip On most systems, Ctrl-Z can be entered at any time to interrupt the output and return to EXEC mode.

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.
