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 3U CompactPCI adapter is auto-
negotiation. The auto-negotiation protocol, as specified by the 100BASE-T standard,
selects the operation mode (half-duplex or full-duplex), and the auto-sensing
protocol selects the speed (10 Mbps or 100 Mbps) for the adapter.
The link speed and modes supported by the Sun Quad FastEthernet 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 Sun Quad FastEthernet 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
auto-negotiation, it advertises its capabilities over the link. The common highest
priority mode supported by both sides is selected for the link operation.
If the Sun Quad FastEthernet adapter is connected to a remote system or interface
that is not capable of auto-negotiation, your system automatically selects the speed
and half-duplex mode.
