The warning icon appears next to the instrument icon if any of
the following errors are seen.
FCS Errors - This counter increments for each frame received that
has an integral length (8-bit multiple) of 64-1518 bytes and
contains a frame check sequence error.
Undersize Frames - This counter increments each time a frame is
received that is less than 64 bytes in length, contains a valid FCS,
and was otherwise well formed. This count does not include
range or length errors.
Undersize frames may be caused by a faulty or corrupt LAN driver.
Oversize Frames - This counter increments each time a frame is
received that exceeds 1518 bytes (non-VLAN) or 1522 bytes (on a
VLAN), contains a valid FCS, and was otherwise well formed.
In general you should not see oversize frames, though their
presence is not a guarantee that the network is failing. Oversize
frames may be caused by a faulty or corrupt LAN driver.
Fragments - This counter increments for each frame received that
contains an invalid FCS and is less than 64 bytes in length. This
includes integral and non-integral lengths.
Jabbers - This counter increments for each frame that exceeds
1518 bytes in length (non-VLAN) or 1522 bytes (on a VLAN) and
contains an invalid FCS. This includes alignment errors.
Possible causes include a bad NIC or transceiver, faulty or corrupt
NIC driver, bad cabling, grounding problems, and nodes jamming
the network due to above normal collision rates.
66
Chapter 4: Network Infrastructure Tests
OneTouch Instrument
A possible solution would be to identify the node(s) that are
sending out excessive errors and replace the defective hardware.
Dropped Frames - This counter increments for each frame that is
received but is later dropped due to a lack of system resources.
Control Frames - This counter increments for each MAC control
frame received (PAUSE and unsupported) from 64 bytes to 1518
bytes (non-VLAN) or 1522 bytes (on a VLAN) in length, with a
valid CRC.
PAUSE Frames - This counter increments each time a PAUSE MAC
control frame is received that is from 64 bytes to 1518 bytes (nonVLAN) or 1522 bytes (on a VLAN) in length, with a valid CRC.
Unknown OP codes - This counter increments each time a MAC
control frame is received that is from 64 bytes to 1518 bytes (nonVLAN) or 1522 bytes (on a VLAN) in length, and contains an
opcode other than PAUSE, but the frame has a valid CRC.
Alignment Errors - This counter increments for each frame
received that is from 64 bytes to 1518 bytes (non-VLAN) or 1522
bytes (on a VLAN) in length, contains an invalid FCS, and is not an
integral number of bytes.
Alignment errors may manifest as an inability to connect to the
network or as intermittent connectivity.
Frame Length Errors - This counter increments for each frame
received in which the 802.3 length field did not match the
number of data bytes actually received (46-1500 bytes). The
counter does not increment if the length field is not a valid 802.3
length, such as an Ethertype value.
Code Errors - This counter increments each time a valid carrier is
present and at least one invalid data symbol is detected.
Carrier Sense Errors - This counter shows the number of times that
the carrier sense condition was lost or was not asserted when
attempting to transmit frames. The count increments at most
once per transmission attempt, even if the carrier sense condition
fluctuates during a transmission attempt.

Advertised Speed indicates the speed(s) offered by the port where
the analyzer is connected.
Actual Speed is the speed that was negotiated when the analyzer
connected to the network.
Advertised Duplex is the duplex capability of the port.
Actual Duplex is the duplex that was negotiated when link was
established.
Rx Pair is the wire pair on which link negotiation was offered by
the port.
Level indicates whether the voltage level of the link negotiation
signal was normal or low. Communication might not be reliable if
the level is low. If the link level is low, the warning icon appears
next to the cable icon on the HOME screen.

PoE Test
Description
Power over Ethernet (PoE) is a system for supplying electrical
power, along with data, over Ethernet cabling. When connected
to PoE Power Sourcing Equipment (PSE), the OneTouch analyzer
can emulate a Powered Device (PD). The OneTouch analyzer
negotiates and reports the advertised class, unloaded and loaded
voltage, loaded power, and the pairs used to deliver power.
Configuration
To configure the PoE test:
1 Connect Port A of the OneTouch AT analyzer to the network.
2 Ensure that a PoE device is
3 On the HOME screen, tap TOOLS .
4 Tap the Wired button.
5 Tap the Power over Ethernet button.

PoE Test
When you select class 4 an option is available for
enabling LLDP Negotiation. Most PSE requires LLDP
negotiation for class 4.
How it Works
The PoE test runs when you tap the AutoTest button on the
touchscreen or the AutoTest key
on the front panel.
The OneTouch analyzer requests the selected class (0-4) from the
PSE. Negotiation is performed for the selected class. A PSE’s
power output can be measured up to the limit specified by the
negotiated class using the OneTouch analyzer’s TruePower
feature.
Results
If the voltage is below the PSE type’s minimum, or the delivered
power is below the class’s specified maximum deliverable power,
the test will fail. If the port meets the class’s voltage and power
requirements, the test will pass.

Wi-Fi Analysis
Tap the Wi-Fi Analysis icon to analyze 802.11 networks, access
points, clients, and channels. The analyzer can be used for
troubleshooting client connectivity and locating devices.
See Chapter 8: "Wi-Fi Analysis," beginning on page 193 for
details.
Nearest Switch Test
Description
Tap the switch to identify the switch name, model, port and VLAN
of the wired connection. If SNMP is enabled, parameters such as
location, description, contact and up time as well as port receive
and transmit statistics are reported.
Configuration
To display System Group information and Statistics, they must be
available on the network via SNMP and you must configure the
OneTouch analyzer for SNMP. See “SNMP” on page 169.
How it Works
Information is displayed based on its availability via Link Level
Discovery Protocol (LLDP), Cisco Discovery Protocol (CDP), Extreme
Discovery Protocol (EDP), Foundry Discovery Protocol (FDP), and
via SNMP. LLDP, CDP, EDP or FDP is used to identify the nearest
switch, the connected port, the switch’s address, and other
information when available. The OneTouch analyzer uses SNMP
to acquire system group information and packet statistics for the
port where the OneTouch analyzer is connected.
