The Cisco 8-Port 10GE Low Queue Oversubscribed Line Card (part number A9K-8T/4-L=) is an expansion module designed to deliver enhanced port density and high-performance connectivity. This line card is equipped with eight 10 Gigabit Ethernet ports, which are ideal for high-bandwidth applications across an enterprise or service provider network. The oversubscribed architecture is specifically aimed at environments where traffic flows have predictable patterns and can tolerate some level of oversubscription without performance degradation.
With low queue buffering, this line card provides a balance between cost efficiency and performance, particularly for non-mission-critical traffic that does not require ultra-high throughput guarantees. Each of the eight ports supports 10 Gigabit Ethernet, ensuring rapid data transfer speeds. It efficiently processes traffic while conserving resources in scenarios where every packet doesn't require maximum priority.
This line card is compatible with the Cisco ASR 9000 Series routers, giving you flexibility in expanding your network’s capacity. The unit can easily integrate into an existing ASR router chassis, facilitating straightforward scalability. Additionally, this model offers carrier-grade performance that service providers and large enterprises seek for their core infrastructure deployment. Its compact design enables it to fit into a range of data centre configurations without requiring excessive space.
The line card is fitted with shared buffer memory, allocating resources dynamically depending on current traffic demands. This makes it an excellent choice for organisations needing to expand port density for normal traffic with less stringent performance requirements.
