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.
The ASR1000-2T+20X1GE has twenty 1 Gigabit Ethernet and two 10 Gigabit Ethernet ports built in; the ASR1000-6TGE has six 10 Gigabit Ethernet ports built in, allowing the ASR 1000 Series Routers to achieve greater Ethernet density and a lower price per port. However, this fixed configuration means that the Ethernet line cards are not compatible with the shared port adapters (SPAs) that are currently used with the SPA interface processors (SIP). Instead, the Ethernet line cards take the slot of the SPA interface processor with the twenty 1 Gigabit Ethernet and two 10 Gigabit Ethernet ports built in, or six 10 Gigabit Ethernet ports built in. Table 1 lists the differences between the fixed Ethernet line cards and the SPA interface processors.
