internal_100_mac Test internal loop-back at 100 Mbps within the
chip.
internal_10_phy Tests loop-back from the physical device at
10 Mbps.
internal_100_phy Tests loop-back from the physical device at
100 Mbp s.
external_10 This test requires a loop-back cable. It tests the
loop-back from the cable at 10 Mbps.
external_100 This test requires a loop-back cable. It tests the
loop-back from the cable at 100 Mbps.
autonegotiate
<speed>
(speed is one of five
options)
Tests the speed the card negotiates. This test has
five options:
0 — Tests for full autonegotiation (highest speed)
10 — Forces tes t at 10 Mbps half duplex
20 — For ce s test at 10 Mbps full dupl e x
100 — Forces test at 100 Mb ps half duplex
200 — Forces test at 1 00 Mbps full duplex
Note: Requires a hub, switch, or loop-back cable.
Als o, au tonegotiate defaults to 10M By te s if the
cable is not connected.
checksum Tests the abilitiy to calculate TCP/IP checksum.
statistics Verifies statistics gathering features of the chip.
echoer #/sender #
(where # is the
number of packets
to send)
This test requires two computers on a private
network: one as the sender, and the other as the
echoer. This test is useful for testing the network
and verifying that data is being pas sed between
the echoer and the sender.
Enter the echoer command first, and then enter
the sender command in the sender system. (This
command sequence is critical!) The two commands
work in tandem. The echoer system displays the
number of packets received and then exits. The
sender system displays a summary of packets
tran smitted and rece ived, corrupted packet s,
number of collisions, and lost packets.
pause Tests the flow controller features of the chip.
mem (default) Slave access set to memory mode.
io Slave access set to io mode.
Command Test
