The interface numbering starts with zero for the GE and 10GE ports, so this line card has ports identified as
Te0/x/0/0 and a Gig0/x/0/0.
Note
For a list of the optics and connectors used by the two 10GE ports on the 2-Port 10GE + 20-Port GE combination
line and for a list of all supported SFP modules, see https://tmgmatrix.cisco.com/home.
8-Port 10-Gigabit Ethernet 2:1 Oversubscribed Line Card with XFP
The 8-Port 10GE 2:1 oversubscribed line card provides eight cages for XFP Ethernet optical interface modules
that operate at a rate of 10 Gbps. The eight XFP modules can be 10GE multimode connections. The 8-Port
10GE line card is a 40 Gbps line rate card with a maximum line rate of 8 ports at 50 percent (2-1
oversubscribed).
Oversubscription results from port pairs sharing the same Network Processor Unit (NPU). The oversubscribed
port pairs are port 0:port 4, port 1:port 5, port 2:port 6 and port 3:port 7.
The 8-Port 10GE line card is available in base, extended, and low-queue versions. All versions are functionally
equivalent, but vary in configuration scale and buffer capacity.
Each XFP cage on the 8-Port 10GE line card has an adjacent Link LED visible on the front panel. The Link
LED indicates the status of the associated XFP port, as described in Line Card LEDs, on page 138.
The following figure shows the 8-Port 10GE line card front panel and LEDs.
