Chapter 7 NPE-G1 and NPE-G2 Installation and Configuration Information
Configuring the Native Gigabit Ethernet Interfaces
Note The Gigabit Ethernet interfaces on the NPE-G1 and NPE-G2 do not support the Inter-Switch Link (ISL)
VLAN encapsulation protocol. We recommends that customers use the IEEE 802.1Q VLAN
encapsulation protocol as an alternative. Where an application requires the use of ISL, this can be
provided by the Fast Ethernet or Gigabit Ethernet port adapters or I/O controllers.
Note The RJ-45 port is the default media.
Changing the Media Type of the Native Gigabit Ethernet GBIC, 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
Step 1 After changing the media type, configure the speed and transmission modes to appropriately match the
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.
Note These commands are only applicable when using the RJ-45 media.
speed { 10 | 100 | 1000 | auto }
duplex { full | half | auto }
