Cisco 12000 Series Router Gigabit Ethernet Line Card
The Gigabit Ethernet line card is the first Ethernet-based product for the Cisco 12000 Series, providing a cost-effective, high-bandwidth solution between colocated Cisco 12000 Series Routers or between Cisco 12000 Series Routers and IP-related equipment such as edge routers, gigabit Ethernet switches, and network servers. The new line card can be configured with one of two interface types: a 1000Base-SX multimode fiber interface with 550-meter reach or a 1000Base-LH single-mode fiber interface for up to 10-km reach.
•Multiple virtual output queues, eliminating head-of-line blocking
•512-KB burst buffers, which smooth out the arriving packet bursts
•256-MB default packet buffer memory to maximize TCP goodput.
•A forwarding table that can accommodate up to one million forwarding entries
•Application-specific integrated circuit (ASIC)-based queuing
•Quality-of-service (QoS) support
•Configurable with up to 256 MB of code and route-table memory
•Default line card packet buffer memory of 128 MB/128 MB (TX/RX)

The single port Gigabit Ethernet line card is orderable and available today.
Note: The Cisco 12000 Series Router GE cards must be configured with either GBIC-SX-MM, GBIC-LH-SM or GBIC-ZX-SM modules. No third-party GBIC is currently approved by Cisco Systems.
1. When filling in the Cisco 12000 Series Router GE sales order DO NOT use the following 7500 GBIC components: (GBIC-SX, GBIC-SX=, GBIC-LX, GBIC-LX=).
2. When employing the GSR12008 or GSR12012 with one or more GE line cards please ensure that the system is configured with a full switching fabric.
3. GE-GBIC-SC-B and the GBIC part numbers can be ordered seperately as spares.
4. GE-SX/LH-SC(=) Does not support ECC.
