Configuring the Native Gigabit Ethernet Interfaces

The NPE-G2 and NPE-G1 report both the RJ-45 and SFP or GBIC GE interface ports as GigabitEthernet
0/1, GigabitEthernet 0/2, and GigabitEthernet 0/3. Before configuring either interface, you must first use
the media-type interface command to select the media type, either the GBIC (gbic) for NPE-G1 or SFP
(sfp) for NPE-G2, RJ-45 (rj45) port.
The RJ-45 port is the default media.
Note
Changing the Media Type of the Native Gigabit Ethernet GBIC or SFP or RJ-45 Ports
To be able to use a particular media port, use Cisco IOS to select the media type. This is done by using
the media-type interface command:
media-type { gbic | sfp | rj45 }
Example:
interface GigabitEthernet 0/1
media-type rj45
end

Configuring the Interface Transmission and Speed Modes

After changing the media type, configure the speed and transmission modes to appropriately match the
Step 1
new interface characteristics. Changing the speed and duplex of an NPE-G1 or NPE-G2 Gigabit Ethernet
interface is done using the speed and duplex interface commands.
These commands are only applicable when using the RJ-45 media.
Note
speed { 10 | 100 | 1000 | auto }
duplex { full | half | auto }
The following speed/duplex settings are supported:

Speed
10, 100, 1000, auto
1000, auto(2)
If you are using the no negotiation auto command, the speed and duplex should be set to a value
other than auto for correct operation.
The only available speed in the no autonegotiation mode is 1000 Mbps; there is no difference
whether 1000 or auto is selected.
