The Cisco ASR 1000 Series Fixed Ethernet Line Card (ASR1000-2T+20X1GE) is a fixed-port Ethernet line card for the Cisco ASR 1000 Series Aggregation Services Routers. The line card is capable of 40-Gbps full-duplex traffic forwarding using a fixed-port interface design. This line card has twenty 1 Gigabit Ethernet ports and two 10 Gigabit Ethernet ports (Figure 1).
The Small Form-Factor Pluggable (SFP) and 10-Gbps SFP (XFP) modules allow you to configure the line card for different media types (copper or fiber) and different optical requirements (single- or multimode fiber), as available. The line cards have one power LED, one line-card status LED, and 22 port or link-status LEDs.

Other aspects of the Cisco ASR 1000 Series Fixed Ethernet Line Card (ASR1000-2T+20X1GE) include:
• SyncE
• Low price per port
• Rich Ethernet Layer 2, Layer 3, IP, IPv6, and Multiprotocol Label Switching (MPLS) packet-processing capabilities as previously provided on Cisco ASR 1000 platforms
• Rich quality-of-service (QoS) functions:
– Ingress and egress QoS as previously provided on Cisco ASR 1000 platforms
– Egress queuing capability as previously provided on Cisco ASR 1000 platforms
– High- and low-priority lanes to Cisco ASR 1000 Series Embedded Services Processor (ESP) for high-priority, low-latency forwarding
The Cisco ASR 1000 Series Fixed Ethernet Line Cards have the twenty 1 Gigabit Ethernet and two 10 Gigabit Ethernet ports built in, allowing the Cisco ASR 1000 Series Routers to achieve greater Ethernet density and a lower price per port. However, this fixed configuration means that the Ethernet line card is not compatible with the Shared Port Adapters (SPAs) that are currently used with the SPA Interface Processor (SIP). Instead, the Ethernet line card takes the slot of the SIP with the twenty 1 Gigabit Ethernet and two 10 Gigabit Ethernet ports built in. Table 1 lists the differences between the Cisco ASR 1000 Fixed Ethernet Line Card and the Cisco ASR 1000 SPA Interface Processor.
