Both native Fast Ethernet/Ethernet ports and Gigabit Ethernet ports are reported as GE0/0 and GE0/1 in software. You
Note
must use the media-type command to select which media type you want to use before you configure these ports. See
"Configure the Native Gigabit Ethernet and Fast Ethernet/Ethernet Interfaces" section on page 28.

GBIC Cabling and Connection Equipment

The Gigabit Interface Converter (GBIC) port is a 1000-Mbps optical interface in the form of an SC-type duplex port that
supports IEEE 802.3z interfaces compliant with the 1000BASEX standard. Gigabit Interface Converter models WS-G5486 or
GBIC-SX=, WS-G5484 or GBIC-LX/LH=, and WS-G5487 or GBIC-ZX-SM= are supported in the Cisco 7401ASR router. For
cabling distances, specifications, and other information, see the online Cisco 7401ASR Router Installation and Configuration
Guide at http://www.cisco.com/univercd/cc/td/doc/product/core/7401/7401icg/index.htm.
All Gigabit Ethernet GBIC ports have SC-type connectors.
