A9K-2T20GE-L is the Cisco ASR 9000 2-port 10GE, 20-port GE Low Queue combo line card. It needs XFPs for the two 10GE ports and SFPs for the twenty GE ports, which run at 100 or 1000 Mbps. It runs Cisco IOS XR Software and needs release 3.9.1 or later.
The L in the part number marks the low-queue version. It has 8 queues per port, 8,000 policers and 4,000 Ethernet flow points (EFPs). Cisco says the low, medium and high queue cards provide the same features and performance and differ in scale.
The medium-queue A9K-2T20GE-B has 96,000 to 192,000 queues, 64,000 to 128,000 policers and 16,000 EFPs, and needs release 3.9. The high-queue A9K-2T20GE-E has 376,000 to 512,000 queues, 256,000 to 512,000 policers and 32,000 EFPs, and also needs release 3.9. Cisco notes that scale depends on hardware and software.
Other ASR 9000 line cards are in the Cisco modules category, including the A9K-4X100GE-SE 4-port 100GE service edge line card.
