Frequently Asked Questions
What primary functions does the Cisco A9K-2T20GE-B line card provide for ASR 9000 Series routers? +
The A9K-2T20GE-B is a high-density Ethernet line card designed to expand port connectivity for Cisco ASR 9000 Series routers. It facilitates multi-service edge routing, providing a scalable solution for high-bandwidth aggregation, IP/MPLS core routing, and edge services within demanding service provider or large enterprise network environments.
How many ports are available on the A9K-2T20GE-B module and what media types are supported? +
This line card features a combination of 2 Gigabit Ethernet (GE) ports and 20 Gigabit Ethernet ports, offering versatile connectivity options for diverse network requirements. It supports various Small Form-Factor Pluggable (SFP) optics, allowing administrators to select the appropriate fiber or copper interfaces to match their existing cabling infrastructure and reach requirements.
Can the A9K-2T20GE-B be deployed in existing ASR 9000 chassis configurations? +
Yes, this module is specifically engineered to be hot-swappable within the Cisco ASR 9000 Series modular chassis. It allows for seamless capacity expansion without requiring a total system shutdown, making it an ideal choice for growing networks that need to maintain high availability while scaling their routing capacity.
What is the performance profile of the A9K-2T20GE-B for heavy-duty routing tasks? +
The A9K-2T20GE-B is built to handle intensive traffic loads, utilizing sophisticated hardware-based packet forwarding to ensure wire-speed performance. Its architecture is optimized for low-latency delivery, effectively supporting latency-sensitive applications like VoIP, video streaming, and real-time cloud services across high-capacity service provider network backbones.
How does this line card handle management and traffic prioritization? +
Management is integrated directly into the Cisco IOS-XR operating system, providing a consistent command-line interface and feature set across your entire router stack. The card supports robust Quality of Service (QoS) mechanisms, including traffic shaping, policing, and sophisticated queuing strategies to ensure mission-critical data takes precedence during periods of high congestion.
Does the A9K-2T20GE-B support Layer 2 and Layer 3 VPN services? +
Absolutely. This line card is fully capable of supporting advanced Layer 2 and Layer 3 MPLS VPN services. It is designed to work within an integrated environment where virtualization and segment routing are essential, ensuring your network can accommodate diverse tenant requirements and complex traffic engineering topologies with ease.
What considerations should I make regarding power and cooling for this line card? +
Because the A9K-2T20GE-B provides significant throughput, it requires adequate power and cooling capacity within the host chassis. Before installation, verify your current power supply unit load and chassis cooling capabilities to ensure the environment stays within operational thermal thresholds, thereby maintaining long-term component reliability and preventing unexpected thermal throttling.
Are there specific licensing requirements to activate the ports on the A9K-2T20GE-B? +
Licensing for Cisco ASR 9000 line cards is typically tied to the specific software features you intend to run, such as advanced routing protocols or security features. We recommend checking your current Cisco IOS-XR entitlement status and feature packages to ensure all desired capabilities are correctly provisioned after physical installation of the hardware.
