5. Activate the new qfe interfaces using the ifconfig command.
For each adapter interface, type the following at the command line, replacing
instance with the interface’s instance number and ip_address with the interface’s IP
address:
For example, if you wanted to activate all of the sample qfe interfaces shown in
Step 4, you would type:
Autonegotiation Protocol
A key feature of the Sun Quad FastEthernet 6U CompactPCI adapter is
autonegotiation. The autonegotiation protocol, as specified by the 100BASE-TX
standard, selects the operational mode (half-duplex or full-duplex), and the
autosensing protocol selects the speed (10 Mbps or 100 Mbps) for the adapter.
The link speed and modes supported by the Sun Quad FastEthernet 6U CompactPCI
adapter are listed as follows, in decreasing order of priority:
■ 100 Mbps, full-duplex
■ 100 Mbps, half-duplex
■ 10 Mbps, full-duplex
■ 10 Mbps, half-duplex
When the system is booted, the adapter advertises these capabilities to the link
partner at the other end of the link (a hub, switch, or another network interface card
[NIC] in a host system). If the link partner also supports autonegotiation, it
advertises its capabilities over the link. The common highest priority mode
supported by both sides is selected for the link operation.
If the adapter is connected to a remote system or interface that is not capable of
autonegotiation, your system automatically selects the speed and the half-duplex
mode.
