Testing Twisted-Pair Cabling

Network cables that fail to provide a link or provide an unreliable link between
the access point and the connected network device may not be compatible
with the IEEE 802.3 Type 10Base-T, or 100Base-TX standards. The twisted-pair
cables attached to the Access Point 420wl must be compatible with the appro-
priate standards. To verify that your cable is compatible with these standards,
use a qualified cable test device.
Testing Access Point-to-Device Network
Communications
You can perform the following communication tests to verify that the network
is operating correctly between the access point and any connected device that
can respond correctly to the communication test.
Link Test -- a physical layer test that sends IEEE 802.2 test packets to any
device identified by its MAC address
Ping Test -- a network layer test used on IP networks that sends test
packets to any device identified by its IP address
These tests can be performed through the access point's console interface
from a terminal connected to the access point or through a Telnet connection.
For more information, see the Management and Configuration Guide, which
is on the Documentation CD-ROM that came with your access point.
These tests can also be performed from an SNMP network management
station running a program that can manage the access point.

Testing End-to-End Network Communications

Both the access point and the cabling can be tested by running an end-to-end
communications test -- a test that sends known data from one network device
to another through the access point. For example, if you have two PCs on the
network between which you can run a Ping test through the access point, you
can use this test to verify that the entire communication path between the two
PCs is functioning correctly.
