The Cisco 8-Port 10GE Medium Queue Oversubscribed Line Card, part number A9K-8T/4-B=, is a highly efficient expansion module designed primarily for the Cisco ASR 9000 Series Aggregation Services Routers. As an oversubscribed line card, this module provides a balance between port density and cost-effectiveness while still delivering reliable high-speed data transfer capabilities.
This line card features 8 ports of 10 Gigabit Ethernet, which are perfect for delivering robust performance in high-demand networking environments. The medium queue feature is specifically designed to optimise performance, offering suitable buffering capacity for applications where medium-sized queues suffice, ensuring smooth data flows even under substantial workloads.
The line card is also equipped to support Twinaxial (Twinax) cables with SFP+ connections, enhancing flexibility in data centre configurations. Each of the 8 ports can be managed, configured, and monitored via Simple Network Management Protocol (SNMP) or similar tools, providing administrators with detailed control and optimised network operations.
With QoS (Quality of Service) policies supported by the hardware, the A9K-8T/4-B= card can prioritise critical traffic, ensuring that lag-sensitive applications always maintain their necessary bandwidth. It also makes use of the ASR 9000's unique distributed architecture, sharing system features such as redundancy and failover reliability, which makes it ideal for large-scale deployments where uptime is essential.
The Cisco 8-Port 10GE Medium Queue Oversubscribed Line Card is a powerful extension for enterprises looking to expand their network infrastructure cost-effectively while ensuring high-speed connections and reliable operations.
