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.
Feature Summary
Packet Layer
•
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)
Ethernet Upper Layers
•Media Access Control (MAC) with full-duplex operation
•8B/10B encoding/decoding
•1000Base-SX multimode, compliant with IEEE 802.3z specifications
•Optional 1000base-LX or 1000base-ZX single-mode interface, compliant with IEEE 802.3z specifications
Physical Layer
•SC duplex connectors
Software Features
•Auto-negotiation
•Flow control (transmit)
•Precedence setting/mapping
•Access Control List (ACL)
