Cisco 2 Port Gigabit Ethernet 1024Mbit/s networking card

2-Port Fast Ethernet Shared Port Adapter The following is a list of some of the significant hardware and software features supported by both the 4-Port 10/100 Fast Ethernet SPA and the 2-Port 10/100/1000 Gigabit Ethernet SPA:

- Autonegotiation of speed, duplex, and IEEE 802.3x flow control (pause frames) when using both copper (RJ45) and fiber (SFP) media types. In copper mode, 10/100/1000 speeds and full/half duplex are advertised during autonegotiation. In fiber mode, only 1000-Mbps speed and full duplex are advertised. The Ethernet pause frame capability is also advertised.

- IEEE 802.3x flow control and asymmetric flow control

- Local (internal) and external loopback
