Interpreting messages in the Event Log
Each line in the Event Log of a module Home page begins with a time and date stamp. However, some of
these lines wrap as a combined result of window width, browser preferences and line length. You may
find this tab easiest to use if you expand the window till all lines are shown beginning with time and date
stamp.
Time and Date Stamp
The time and date stamp reflect one of the following:

GPS time and date directly or indirectly received from the CMM4.

NTP time and date from a NTP server (CMM4 may serve as an NTP server)

The running time and date that you have set in the Time & Date web page.
Page 9-29
Chapter 9: Operation
System information
Note
In the Time & Date web page, if you have left any time field or date field unset and clicked
the Set Time and Date button, then the time and date default to 00:00:00 UT :
01/01/00.
A reboot causes the preset time to pause or, in some cases, to run in reverse. Additionally, a
power cycle resets the running time and date to the default 00:00:00 UT : 01/01/00.
Thus, whenever either a reboot or a power cycle has occurred, must reset the time and date
in the Time & Date web page of any module that is not set to receive sync.
Event Log Data Collection
The collection of event data continues through reboots and power cycles. When the buffer allowance for
event log data is reached, the system adds new data into the log and discards an identical amount of the
oldest data.
Each line that contains the expression WatchDog flags an event that was both:

considered by the system software to have been an exception

recorded in the preceding line.
Conversely, a Fatal Error () message flags an event that is recorded in the next line. Some exceptions
and fatal errors may be significant and require either operator action or technical support.

Messages that Flag Abnormal Events
The messages listed below flag abnormal events and, case by case, may signal the need for corrective

Viewing the Layer 2 Neighbors
In the Layer 2 Neighbors tab, a module reports any device from which it has received a message in Link
Layer Discovery Protocol within the previous two minutes. Given the frequency of LLDP messaging, this
means that the connected device will appear in this tab 30 seconds after it is booted and remain until two
minutes after its shutdown.

Interpreting Bridging Table statistics
If NAT (network address translation) is not active on the SM/BHS, then the Bridging Table page provides
the MAC address of all devices that are attached to registered SMs/BHS (identified by LUIDs).
The SM/BHS management MAC addresses are also added in bridge table upon SMs/BHS registration.
These entries will be remove automically from the table once SMs/BHS is de-registered. This alleviates
the arp cache > bridge cache timeout problems.
The bridging table allows data to be sent to the correct module as follows:

For the AP/BHM, the uplink is from RF to Ethernet. Thus, when a packet arrives in the RF interface to
the AP/BHM, the AP/BHM reads the MAC address from the inbound packet and creates a bridging
table entry of the source MAC address on the other end of the RF interface.

For the SM/BHS, the uplink is from Ethernet to RF. Thus, when a packet arrives in the Ethernet
interface to one of these modules, the module reads the MAC address from the inbound packet and
creates a bridging table entry of the source MAC address on the other end of the Ethernet interface.
Figure 198 Bridging Table page
The Bridging Table supports up to 4096 entries.
Interpreting Translation Table statistics
When Translation Bridging is enabled in the AP, each SM keeps a table mapping MAC addresses of
devices attached to the AP to IP addresses, as otherwise the mapping of end-user MAC addresses to IP
addresses is lost. (When Translation Bridging is enabled, an AP modifies all uplink traffic originating from
registered SMs such that the source MAC address of every packet is changed to that of the SM which
bridged the packet in the uplink direction.)

Note:
PMP 450 AP running in Gigabit Ethernet Mode displays error
“RcfFifoNoBuf” which indicates packet loss.
For 450 AP platforms, if ethernet auto-negotation is set to

This field displays how many late collisions occurred on the Ethernet
controller. A normal collision occurs during the first 512 bits of the frame
transmission. A collision that occurs after the first 512 bits is considered a late
collision.
Caution
A late collision is a serious network problem because the frame being
transmitted is discarded. A late collision is most commonly caused by
a mismatch between duplex configurations at the ends of a link
segment.

inoctets Count
This field displays how many octets were received on the interface, including
those that deliver framing information.
inucastpkts Count
This field displays how many inbound subnetwork-unicast packets were
delivered to a higher-layer protocol.

indiscards Count
This field displays how many inbound packets were discarded without errors
that would have prevented their delivery to a higher-layer protocol. This stat is
pegged whenever corrupt data is received by software or whenever the RF
Software Bridge queue is full.
Corrupt data is a very unusual event because all packets are CRC checked
by hardware before being passed into software.
The likely case for indiscards is if the RF bridge queue is full. If this is the
case the radio is most likely PPS limited due to excessive small packet traffic
or a problem at the Ethernet interface. If there is a problem at the Ethernet
interface there is likely to be discards at the Ethernet as well.

Different types of Sounding states are:

UNKNOWN: VC has recently registered to the AP but not registered with the channel manager yet.

NEW: VC has been registered with the channel manager and will soon transition to ASSESSING.

ASSESSING: AP will instruct SM to take the channel measurements. Channel estimates and spatial
frequencies will be calculated.

TRACKING: Valid measurements resulted in good channel estimates and spatial frequency. This VC can
now be used for MU-MIMO.

INVALID: Inconsistent measurements resulting in no channel estimate or spatial frequency. This VC cannot
be used for MU-MIMO and it will ultimately be re-assessed.

Generally if VC is UNTRUSTED, this means something went wrong. The fault codes can help to describe what is
wrong with this channel (If VC is TRACKING this will generally indicate 0 (SOUNDING_FAULT_NONE)).
Error codes are:

SOUNDING_FAULT_VC_CEST: Channel Estimate Error, could be due to issues with the channel..

SOUNDING_FAULT_NULLING_SNR: Channel Estimate Error, could be due to issues with the channel.

SOUNDING_FAULT_SM_ERROR: SM returned Error code when taking channel measurements.

SOUNDING_FAULT_CHANNEL_DISTORTION: Channel Distortion is beyond tolerance, could be due to
issues with the channel.

SOUNDING_FAULT_UNSTABLE_SF: Inconsistent Spatial Frequency, could be due to issues with the
channel.

SOUNDING_FAULT_SF_DEVIATION: Inconsistent Spatial Frequency, could be due to issues with the
channel.

SOUNDING_FAULT_INTERNAL_ERROR: Could be due to incompatible software (AP – SM), or other
catastrophic software issue.

Attribute
Meaning
Responses
Number of sounding responses (full VC assessments or condensed nulling)
sent from the SM to the AP
Responses
Suppressed
Number of sounding requests suppressed by the SM.
The reason why a sounding response is suppressed is because the error
calculated during the sounding process is lower than the threshold set by the
AP. In this case, the SM does not need to transmit a sounding response to
the AP
Errors
Number of errors in the sounding process at the SM
Examples of events that count as errors:

Sounding type is not supported

IQ capture not enabled: for example, if sounding requested too soon after
SM boot

IQ capture did not complete

Sounding processing took too long
Version Mismatch
Number of sounding requests with mismatched version numbers
The Sounding Acquisition Command contains a version number. The SM
checks its own version number and flags any mismatch. Currently, AP and
SMs use V1.
Max Request Interval
Largest time between two sounding requests received from the 450m AP
Avg Request Interval
Average time between two sounding requests received from the 450m AP

Table 229 Data VC page attributes
Attribute
Meaning
Subscriber
This field displays the LUID (logical unit ID), MAC address and Site Name of
the SM/BHS. As each SM or BHS registers to the AP/BHM, the system
assigns an LUID of 2 or a higher unique number to the SM/BHS. If a SM/BHS
loses registration with the AP/BHM and then regains registration, the SM/BHS
retains the same LUID.
VC
This field displays the virtual channel number. Low priority channels start at
VC18 and count up. High priority channels start at VC255 and count down. If
one VC is displayed, the high-priority channel is disabled. If two are
displayed, the high-priority channel is enabled.

Inbound Statistics,
discards
This field displays how many inbound packets were discarded without errors
that would have prevented their delivery to a higher-layer protocol. Inbound
discard statistics are incremented similar to the indiscards stat on the RF
control block stats page. The sum of all data VC indiscards must be close to
the RF control block in discards. If indiscards are evenly distributed across
SMs, then the radio is PPS limited due to either excessive small packet
transmissions, or a problem at the Ethernet link. If indiscards are contained to
one or a few SMs, then there is likely a problem at or underneath the SM
which is incrementing the count.

Outbound Statistics,
errors
This field displays how many outbound packets contained errors that
prevented their transmission.
Queue Overflow
This is a count of packets that were discarded because the queue for the VC
was already full. If Queue Overflows are being seen across most or all SMs,
then there is either an interferer local to the AP or the APs RF link is at
capacity. If Queue Overflows are being seen at one or only a few SMs, then it
is likely that there is a problem with those specific links whether it is
insufficient signal strength, interferer, or a problem with the actual SM
hardware.
High Priority Queue
This is a count of packets that were received on high priority queue.

Interpreting Throughput statistics
The 450 Platform Family has a Statistics > Throughput page which shows historical information about
sector or backhaul throughput and packet discards. This page is applicable for AP and BHM modules.
This information can be useful to identify an overloaded sector or heavy bandwidth users. This page also
shows the user throughput in terms of data rate (kbps) and packet rate (packets per second, or PPS), as
well as the average packet size during the sample period.
Operators may set the AP/BHM to send an SNMP trap when it detects an RF overload condition based
on a configurable threshold.
The following configuration parameters are available on the Throughput tab GUI pane and a radio reboot
is not required when configuring these parameters:
Table 230 RF overload Configuration attributes – AP/BHM
Attribute
Meaning
Throughput Monitoring
This enables or disables the monitoring of sector throughput and packet
discards. This parameter is disabled by default.
SNMP Trap on RF
Overload
This enables or disables the sending of an SNMP trap when an AP/BHM
overload condition is reached (based on Downlink RF Overload Threshold).
Downlink RF Overload
Threshold
This parameter determines the overload threshold in percent of packets
discarded that triggers the generation of an SNMP trap.
Downlink RF Link
Status
This field displays the status of the capacity of the RF link.
Time Period Length
These two configuration parameters determine what set of collection samples
to show on the GUI display. The Time Period Length can be set from one to
three hours. Time Period Ending allows the operator to set the end time for
the set of collection samples to display.
Time Period Ending
Below the configuration settings are three tables that display the statistics that are collected.
Board Performance statistics
This table contains a row that corresponds to each 1 minute statistics collection interval. Each row
contains the following data aggregated for the entire AP/BHM:
Page 9-6

Board Throughput statistics
This table contains a row that corresponds to each one minute statistics collection interval. This table may
be used to determine if there are problems with any of the interfaces. For example, if the Ethernet in
packets is much higher than the RF out packets it could indicate a denial of service (DoS) attack on the
AP/BHM. Each row contains the following data aggregated for the entire AP/BHM:

RF Interface Queue during the collection interval
Discards % (in/out) – Percent of the total packets received / transmitted that had to be discarded
during the collection interval
LUID RF Throughput statistics
This table contains a row that corresponds to each active LUID served by the AP/BHM. Note that an LUID
may be assigned 1 or 2 VCs. If the LUID is assigned 2 VCs, then the data in the table is the sum of the
activity for both VCs. This table may be used to determine which LUIDs are experiencing overload so that
corrective action can be taken (i.e. fixing a poor RF link or moving a heavily loaded link to a less
congested AP/BHM). Each row contains counters and statistics related to the RF Interface that are
updated once per minute:

Inbound Statistics - Statistics collected at the RF Interface for the Uplink:

System statistics
Interpreting Overload statistics
The Statistics > Overload page displays statistics on packet overload and resultant packet discards.
Unlike the other fields, the Total Packets Overload Count is expressed in only this page. It is not a count
of how many packets have been lost, but rather of how many discard events (packet loss bursts) have
been detected due to overload condition.
This statistics page is applicable for all modules (AP/SM/BHM/BHS) and explained in Table 231.
Table 231 Overload page attributes – AP/SM/BHM/BHS
Attribute
Meaning
Total Packets
Overload Count
This field represents the sum of all RF and Ethernet in/out discards.
Ethernet In Discards
This field represents the number of packets tossed due to the Ethernet queue
being full. If a climb in this stat accompanies a climb in RF Out Discards stat,
then most likely the board is at RF capacity either due to traffic exceeding the
RF pipe, or interference temporarily limiting the RF throughput. If this stat
climbs without the RF Out Discards stat climbing, then the radio is most likely
PPS limited.
Ethernet Out Discards
This field represents the number of packets tossed due to an Ethernet out
overload. This stat must not climb in normal operation because the Ethernet
link is much higher capacity than the RF link. If this stat is incrementing, then
either the Ethernet link is established at a low speed (i.e. 10Mbps – half
duplex), or there is a problem with cabling/Ethernet hardware.
RF In Discards
This field indicates the number of packets tossed due to no resources
available within the radio to process them. This stat also must not be
increasing because the system is designed to shed packets on the RF Out
interface. If this stat is incrementing the board, it is most likely congested due
to high PPS rate in combination with an Ethernet Out problem, which limits
packet flow off the device.
Page 9-9
Chapter 9: Operation
RF Out Discards
System statistics
This field indicates the number of packets tossed due to RF link at capacity.
This stat will increase whenever the RF link is at capacity. When the internal
FPGA RF input queue overflows, this stat is incremented. If this stat is seen
to be incrementing at the AP, then the sector is congested. If seen at the SM,
the number of Contention Slots must be looked at to ensure that enough
Contention Slots are allocated to allow for bandwidth requests to be seen at
the AP.
Note
450m Overload:
The 450m Series AP is designed to handle high load in terms of high throughput and high
PPS. In terms of throughput, 450m is designed to achieve 3x or more throughput
improvement over 450 and 450i Series products. In terms of packets per second (PPS),
450m is designed to handle up to 100k PPS.
Overload occurs when the offered load exceeds the above limits. When overload occurs,
450m will start discarding packets and TCP throughput will degrade due to packet loss.
It’s worth noting that Frame Utilization statistics (Statistics > Frame Utilization tab: Frame
Utilization: Downlink and Uplink) are not necessarily indicative of overload condition. They
show how much the TDD frame is utilized. High frame utilization depends on:

High traffic during busy periods: those statistics will be close to 100% and almost all
slots will be utilized. In this case if the Overload statistics show that packets are
discarded then this is an indication of overload condition.

High percentage of VCs with low modulation with moderate traffic. Those VCs will
require more slots to service them (due to low modulation) and the frame utilization will
be high. In this case the TDD frame is fully utilized but the system is at low capacity and
is not in an overload condition.
450m has higher PPS than 450 and 450i and supports higher throughput through spatial
multiplexing, therefore when a 450m replaces an overloaded 450 or 450i AP the 450m will
not be overloaded under the same conditions but the frame utilization may still show close to
100%; this should not alarm the customer. The overload statistics shall be monitored on
450m to see if it is overloaded or not.
Interpreting DHCP Relay statistics
The Statistics > DHCP Relay page displays requests and replies received, relayed and discarded when
the AP is configured as a DHCP relay. Typically, in a working DHCP relay configuration a one-to-one ratio
is established between requests and replies that are received and relayed. This statistics page is only
applicable for PMP (AP and SM modules) and it is explained in Table 232.

This forms the first step of identifying the TDD frame utilization information. If the user finds excessive
utilization based on this stats, the second step would be to take several actions like sectorization, tuning
the uplink/downlink ratio etc. to improve RF channel utilization. Efficient use of the TDD frame will help to
achieve optimum performance of link.

Frame Utilization Interval
Statistics Display interval
This allows to configure timer interval to monitor and display the
frame utilization statistics. It can be configured for 1 minute (low
interval), 5 minutes (medium interval) or 15 minutes (high interval)
based on requirement.
MU-MIMO Utilization
Spatial Utilization
This is a table (32 rows) that lists frame utilization for each spatial
frequency (SF) range with following information:

Spatial frequency: Range of spatial frequency for each bin.
Each bin includes 32 consecutive spatial frequency values.

Azimuth (degrees): Azimuth range in degrees corresponding to
the spatial frequencies of the bin. The zero degree azimuth is
boresight.
Note:
Some SF ranges correspond to multiple azimuth ranges.
This is due to the fact that for some spatial frequencies
the AP generates beams in multiple azimuth directions.
The SM can be physically located in any of the azimuth
ranges.
Spatial Utilization

Instantaneous (%): Frame utilization for the SF bin, updated
every 500 ms. The frame utilization percentage accounts for all
traffic, both sector mode and MU-MIMO transmissions.

Total (%): Average utilization in the SF bin for the past 1/5/15
minutes, as selected in the Statistics Display Interval.

Max (%): Maximum Instantaneous utilization in the 1/5/15 minute
interval

Min (%): Minimum Instantaneous utilization in the 1/5/15 minute
interval

VCs in Range: List of VCs with spatial frequency falling in the
bin.
Note:
The size of each SF bin is smaller than the beam
generated by the AP during a MU-MIMO transmission.
This means that when a VC in a bin is scheduled for a
MU-MIMO transmission, the adjacent bins also receive
the signal, and the transmission is counted towards their
utilization as well. Bins with consistent low utilization
indicate the areas of the sector where more SMs could
be installed, or the customers that could be offered
higher data plans.

Grouping
Instantaneous Distribution
System statistics
This specifies the distribution of group size for the past 1/5/15
minutes. For each group size, from 0 to 7, the table shows the
percentage of slots using that group size.

A group size of 0 corresponds to unused slots.

A group size of 1 corresponds to sector mode transmissions
(ungrouped).

A group size of 2 to 7 corresponds to MU-MIMO transmissions.
This table is updated every 500 ms and displays the following:

Group: Each row corresponds to the top (most active) 1, 2, 4, 8,
16, 32, 64, 128, and 256 VCs.

Median Slot Count: Median value of the average number of slots
scheduled for the VCs in each group in the past 500 ms.

VCs in Group: List of VCs belonging to each bin where each bin
includes all VCs listed in preceding rows along with the VCs
listed in the corresponding row.
For example, the row labeled “Top 32 VCs” considers up to 32
VCs, which are: one VC listed in “Top VC” row, plus one VC
listed in “Top 2 VCs” row, plus 2 VCs listed in “Top 4 VCs” row,
plus four VCs listed in “Top 8 VCs” row, plus 8 VCs listed in “Top
16 VCs” rows, plus up to 16 VCs listed in “Top 32 VCs” row. If
the number of VCs in the sector is less than 32, this row will
include less than 16 VCs; if the number of VCs in the sector is
equal to or greater than 32, this row will include 16 VCs.
Note:
For best MU-MIMO operation, the distribution of the
median values in this table should be as close to flat as
possible. If many VCs are equally active, there is a
higher probability of being able to group their
transmissions. If only a few VCs are active, the
probability of grouping transmissions is lower, and both
the Average MU-MIMO Group size and the Multiplexing
Gain are expected to be lower.
Average MU-MIMO Group

System statistics
Canopy MAC
Acknowledgment Utilization
This specifies the portion of the Sector Utilization used for
acknowledgments transmission.
Broadcast/Multicast
Utilization
This specifies the portion of the Sector Utilization used for broadcast
and multicast transmissions.
Multiplexing Gain
This specifies the ratio between the number of logical slots and the
number of physical slots used.
A physical slot is an OFDM symbol. In non MU-MIMO mode, each
logical slot is sent during one physical slot. In MU-MIMO mode a
number of logical slots are sent during a physical slot, equal to the
number of VCs in the group. A logical slot carries new information; if
data is repeated in a group, because some VCs have more data to
send then others, then the repeated transmissions are not counted as
a logical slots.
Without MU-MIMO operation, the multiplexing gain would always be
equal to 1.
With MU-MIMO operation, this number accounts for parallel
transmissions to multiple users in the MU-MIMO group.
The difference between the Average MU-MIMO Group Size and the
Multiplexing Gain is that the Average MU-MIMO Group Size only
considers the MU-MIMO groups, and it averages the number of VCs
in the Group. The Multiplexing Gain also considers non MU-MIMO
transmissions, which are counted as groups of size 1.
Frame Utilization
Downlink
This indicates the percentage of downlink data slots used against the
maximum number of slots possible in the configured interval.
Uplink
This indicates the percentage of uplink data slots used against the
maximum number of uplink slots possible in the configured interval.
Bandwidth Requests
The "Bandwidth Request" is a message sent from the SM to the AP
asking to be scheduled for bandwidth to send in the uplink. This gets
transmitted in the unscheduled portion of the uplink. Unscheduled
uplink is defined as Contention Slots + unscheduled uplink slots.
Since this is sent in the unscheduled portion of the uplink, it will result
in collisions when SMs randomly pick the same slot.
The "Bandwidth Request Missed" metrics are to add data to know
how many of requests are colliding. If it is near 100%, then near all of
the SM’s bandwidth requests are getting through to the AP, so this a
is near perfect scenario. If it is significantly less than that, you may be
experiencing uplink latency as your SMs are attempting to request
bandwidth and are unable to do so.
Also note that if it is consistently at 100% the AP may be able to
reduce its contention slots to a lower value and gain more data slots.

Radio Recovery
This section describes:

How to recover a PMP/PTP 450i and PMP 450m Series ODUs from configuration errors or software
image corruption

How to override a PMP/PTP 450 Series ODUs from forgotten IP address and password to factory
default
Radio Recovery Console– PMP/PTP 450i/450b and
PMP 450m
Recovery mode allows to restore IP address and password. Also, it allows new main application software
to be loaded even when the integrity of the existing main application software image has been
compromised. The most likely cause of an integrity problem with the installed main application software is
where the power supply has been interrupted during a software upgrade.
Note
When Recovery has been entered through a power on/off/on cycle, the ODU will revert to
normal operation if no web access has been made to the unit within 30 seconds. This
prevents the unit remaining inadvertently in recovery following a power outage.
Options in recovery mode are:

Boot with normal operation

Boot with default Canopy system software settings

Load a previous SW image
The last most recent software images loaded to the board are retained. However the factory image is not
retained.
Boot with default Canopy system software settings (similar to the hardware Default Plug based on 450
Platforms Family).
Note
The unit may enter recovery console automatically, in response to some failures.
Note
Once the unit has entered recovery, it will switch back to normal operation if no access has
been made to the recovery web page within 30 seconds.
Use below procedure to enter in recovery console manually.

out (about 1 - 2 seconds).
When the unit is in recovery mode, access the web interface by entering the default IP
address 169.254.1.1. The Recovery Image Warning page is displayed.
Review the Boot Selection (Table 244).

Radio Recovery
Note
The radio enters recovery mode when a short power cycle is used. The radio will boot
normally if power has been removed for a longer period (typically 5 - 10 seconds).
Default Mode (or Default/Override Plug) - PMP/PTP 450
Series
The default modeallows to temporarily override some PMP/PTP 450 Series ODU settings and thereby
regain control of the module by powering the module on with the Default Plug inserted into the unit’s
synchronization (RJ11) port.
This override plug is needed for access to the module in any of the following cases:

You have forgotten either
o the IP address assigned to the ODU.
o the password that provides access to the ODU.

The ODU has been locked by the No Remote Access feature.

You want local access to a module that has had the 802.3 link disabled in the Configuration page.
You can configure the module such that, when it senses the override plug, it responds by either

resetting the LAN1 IP address to 169.254.1.1, allowing access through the default configuration
without changing the configuration, whereupon you will be able to view and reset any non-default
values as you wish.

resetting all configurable parameters to their factory default values.
Note
The Default Plug is available from Best-Tronics Manufacturing, Inc.
See http://www.best-tronics.com/cambium.htm as Part BT-0583 (RJ-11 Default Plug).
Alternatively, you can fabricate an override plug. See Override plug cable on page 5-15 for
pinout.

Radio Recovery
Using the Default/Override Plug
The following section details usage of the override plug to regain access to PMP/PTP 450 Series ODU.
Note
While the override plug is connected to a PMP/PTP 450 Series ODU, the ODU can neither
register nor allow registration of another ODU.
Note
Since the 900 MHz SM is based on the 450 Series, it only supports the "Default Plug" mode
of overriding.
Use below procedure to enter in default mode manually.
Procedure 36 Default mode
Insert the override plug into the RJ-11 GPS utility port of the module.
Power cycle by removing, then re-inserting, the Ethernet cable.
RESULT: The module boots with the default IP address of 169.254.1.1, password fields
blank, and all other configuration values as previously set.
Wait approximately 30 seconds for the boot to complete.
Remove the override plug.
Set passwords and IP address as desired.
Change configuration values if desired.
Click the Save Changes button.
Click the Reboot button.

FCC specific information
FCC compliance testing
With GPS synchronization installed, the system has been tested for compliance to US (FCC)
specifications. It has been shown to comply with the limits for emitted spurious radiation for a Class B
digital device, pursuant to Part 15 of the FCC Rules in the USA. These limits have been designed to
provide reasonable protection against harmful interference. However the equipment can radiate radio
frequency energy and, if not installed and used in accordance with the instructions, may cause harmful
interference to other radio communications. There is no guarantee that interference does not occur in a
particular installation.
Note
A Class B Digital Device is a device that is marketed for use in a residential environment,
notwithstanding use in commercial, business and industrial environments.
Note
Notwithstanding that Cambium has designed (and qualified) the 450 Platform Family ODUs
to generally meet the Class B requirement to minimize the potential for interference, the 450
Platform Family ODU range is not marketed for use in a residential environment.

This chapter contains procedures for identifying and correcting faults in a 450 Platform Family link. These
procedures can be performed either on a newly installed link, or on an operational link if communication is
lost, or after a lightning strike.
The following topics are described in this chapter:

General troubleshooting procedure on page 11-2

Troubleshooting procedures on page 11-5

Power-up troubleshooting on page 11-13


General troubleshooting procedure
General troubleshooting procedure
General planning for troubleshooting
Effective troubleshooting depends in part on measures that you take before you experience trouble in
your network. Cambium recommends the following measures for each site:

Identify troubleshooting tools that are available at your site (such as a protocol analyzer).

Identify commands and other sources that can capture baseline data for the site. These may include:
o Ping
o Tracert or traceroute
o Link Capacity Test results
o Throughput data
o Configuration tab captures
o Status tab captures
o Session logs
o Web browser used

Start a log for the site.

Include the following information in the log:
o Operating procedures
o Site-specific configuration records
o Network topology
o Software releases, boot versions and FPGA firmware versions
o Types of hardware deployed
o Site-specific troubleshooting processes
o Escalation procedures

Capture baseline data into the log from the sources listed above
Page 11-2
Chapter 11: Troubleshooting
General troubleshooting procedure
General fault isolation process
Effective troubleshooting also requires an effective fault isolation methodology that includes the following:

Attempting to isolate the problem to the level of a system, subsystem, or link, such as
o AP to SM
o AP to CMM4
o AP to GPS
o Backhaul(BH)
o Backhaul(BH) to CMM4
o Power

Researching Event Logs of the involved equipment

Interpreting messages in the Event Log

Answering the questions listed in the following sections.

Reversing the last previous corrective attempt before proceeding to the next.

Performing only one corrective attempt at a time.
Questions to help isolate the problem
When a problem occurs, attempt to answer the following questions:

What is the history of the problem?
o Have we changed something recently?
o Have we seen other symptoms before this?

How wide-spread is the symptom?
o Is the problem on only a single SM? (If so, focus on that SM.)
o Is the problem on multiple SMs? If so
is the problem on one AP in the cluster? (If so, focus on that AP)
is the problem on multiple, but not all, APs in the cluster? (If so, focus on those APs)
is the problem on all APs in the cluster? (If so, focus on the CMM4 and the GPS signal.)

Based on data in the Event Log
o does the problem correlate to External Hard Resets with no WatchDog timers? (If so, this
indicates a loss of power. Correct your power problem.)
o is intermittent connectivity indicated? (If so, verify your configuration, power level, cables and
connections and the speed duplex of both ends of the link).
o does the problem correlate to loss-of-sync events?

Are connections made via shielded cables?

Does the GPS antenna have an unobstructed view of the entire horizon?

Has the site grounding been verified?
Secondary Steps
After preliminary fault isolation is completed through the above steps, follow these:

Module has lost or does not establish connectivity
To troubleshoot a loss of connectivity, perform the following steps:
Procedure 37 Troubleshooting loss of connectivity
Isolate the end user/SM from peripheral equipment and variables such as routers,
switches and firewalls.
Set up the minimal amount of equipment.
On each end of the link:

Check the cables and connections.

Verify that the cable/connection scheme—straight-through or crossover—is correct.

Verify that the LED labeled LNK is green.

Access the General Status tab in the Home page of the module.

Verify that the SM is registered.

Verify that Received Power Level is -87 dBm or higher.

Access the IP tab in the Configuration page of the module.

Verify that IP addresses match and are in the same subnet.

If RADIUS authentication is configured, ensure that the RADIUS server is operational
Page 11-5
Chapter 11: Troubleshooting
Troubleshooting procedures
On the SM end of the link:

Verify that the PC that is connected to the SM is correctly configured to obtain an IP
address through DHCP.

Execute ipconfig (Windows) or ifconfig (linux)

Verify that the PC has an assigned IP address.
On each end of the link:

Access the General tab in the Configuration page of each module.

Verify that the setting for Link Speeds (or negotiation) matches that of the other
module.

Access the Radio tab in the Configuration page of each module.

Verify that the Radio Frequency Carrier setting is checked in the Custom Radio
Frequency Scan Selection List.

Verify that the Color Code setting matches that of the other module.

Access the browser LAN settings (for example, at
Tools > Internet Options > Connections > LAN Settings in Internet Explorer).

Verify that none of the settings are selected.

Access the Link Capacity Test tab in the Tools page of the module.

Perform a link test

Verify that the link test results show efficiency greater than 90% in both the uplink and
downlink

Execute ping.
Verify that no packet loss was experienced.
Verify that response times are not significantly greater than

4 ms from AP to SM

15 ms from SM to AP
Replace any cables that you suspect may be causing the problem.
Note
A ping size larger than 1494 Bytes to a module times out and fails.
However, a ping of this size or larger to a system that is behind a Canopy
module typically succeeds. It is generally advisable to ping such a system,
since Canopy handles that ping with the same priority as is given all other
transport traffic. The results are unaffected by ping size and by the load on
the Canopy module that brokers this traffic.
After connectivity has been re-established, reinstall network elements and variables that
you removed in Step 1.

NAT with DHCP Client (DHCP selected as the Connection Type of the WAN interface) and DHCP
Server

NAT with DHCP Client (DHCP selected as the Connection Type of the WAN interface)

NAT with DHCP Server

NAT without DHCP
To troubleshoot a loss of connectivity for a SM configured for NAT/DHCP, perform the following steps.
Procedure 38 Troubleshooting loss of connectivity for NAT/DHCP-configured SM
Isolate the end user/SM from peripheral equipment and variables such as routers,
switches and firewalls.
Set up the minimal amount of equipment.
On each end of the link:

Check the cables and connections.

Verify that the cable/connection scheme—straight-through or crossover—is correct.

Verify that the LED labeled LNK is green.
At the SM:

Access the NAT Table tab in the Logs web page.

SM Does Not Register to an AP
To troubleshoot a SM failing to register to an AP, perform the following steps.
Procedure 39 Troubleshooting SM failing to register to an AP
Access the Radio tab in the Configuration page of the SM.
Note the Color Code of the SM.
Access the Radio tab in the Configuration page of the AP.
Verify that the Color Code of the AP matches that of the SM.
Note the Radio Frequency Carrier of the AP.
Verify that the value of the RF Frequency Carrier of the AP is selected in the Custom
Radio Frequency Scan Selection List parameter in the SM.
In the AP, verify that the Max Range parameter is set to a distance slightly greater than
the distance between the AP and the furthest SM that must register to this AP.
Verify that no obstruction significantly penetrates the Fresnel zone of the attempted link.
Access the General Status tab in the Home page of each module.
10
Remove the bottom cover of the SM to expose the LEDs.
11
Power cycle the SM.
RESULT: Approximately 25 seconds after the power cycle, the green LED labeled LNK
must light to indicate that the link has been established. If the orange LED labeled SYN is
lit instead, then the SM is in Alignment mode because the SM failed to establish the link.
12
If the AP is configured to require authentication, ensure proper configuration of RADIUS
or Pre-shared AP key.
13
In this latter case and if the SM has encountered no customer-inflicted damage, then
request an RMA for the SM.

Module has lost or does not gain sync
To troubleshoot a loss of sync, perform the following steps.
Procedure 40 Troubleshooting loss of sync
Access the Event Log tab in the Home page of the SM
Check for messages with the following format:
RcvFrmNum =
ExpFrmNum =
If these messages are present, check the Event Log tab of another SM that is registered
to the same AP for messages of the same type.
If the Event Log of this second SM does not contain these messages, then the fault is
isolated to the first SM.
If the Event Log page of this second SM contains these messages, access the GPS
Status page of the AP.
If the Satellites Tracked field in the GPS Status page of the AP indicates fewer than 4 or
the Pulse Status field does not indicate Generating Sync, check the GPS Status page of
another AP in the same AP cluster for these indicators. GPS signal acquisition must not
take longer than 5 minutes from unit startup.
If these indicators are present in the second AP, then:

Verify that the GPS antenna still has an unobstructed view of the entire horizon.

Visually inspect the cable and connections between the GPS antenna and the
CMM4. If this cable is not shielded, replace the cable with shielded cable
If these indicators are not present in the second AP, visually inspect the cable and
connections between the CMM4 and the AP antenna. If this cable is not shielded, replace
the cable with shielded cable.

Troubleshooting procedures
Module does not establish Ethernet connectivity
To troubleshoot a loss of Ethernet connectivity, perform the following steps:
Procedure 41 Troubleshooting loss of Ethernet connectivity
Verify that the connector crimps on the Ethernet cable are not loose.
Verify that the Ethernet cable is not damaged.
If the Ethernet cable connects the module to a network interface card (NIC), verify that
the cable is pinned out as a straight-through cable.
If the Ethernet cable connects the module to a hub, switch, or router, verify that the cable
is pinned out as a crossover cable.
Verify that the Ethernet port to which the cable connects the module is set to autonegotiate speed.
Verify VLAN configuration in the network, which may cause loss of module access if the
accessing device is on a separate VLAN from the radio.
Power cycle the module.
RESULT: Approximately 25 seconds after the power cycle, the green LED labeled LNK
must light up to indicate that the link has been established. If the orange LED labeled
SYN is lit instead, then the module is in Alignment mode because the module failed to
establish the link.
In this latter case and if the module has encountered no customer-inflicted damage, then
request an RMA for the module.

Reference
Specifications
Please see the Specification sheets listed on the Cambium Networks website for the most up-to-date
450m Series cnMedusa AP specifications:
http://www.cambiumnetworks.com/resources/pmp-450m/
450m overload
The 450m Series AP is designed to handle high load in terms of high throughput and high PPS. In terms
of throughput, 450m is designed to achieve 3x or more throughput improvement over 450 and 450i Series
products. In terms of packets per second (PPS), 450m is designed to handle up to 100k PPS.
Overload occurs when the offered load exceeds the above limits. When overload occurs, 450m will start
discarding packets and TCP throughput will degrade due to packet loss. The 450 family of products have
a set of overload statistics that can be used to monitor overload conditions (Statistics >Overload tab).
Page I
Chapter 11: Troubleshooting
Logs
The above statistics shall be monitored over time for overload conditions over consecutive periods. Refer
to Interpreting Overload statistics for description of those statistics.
It’s worth noting that Frame Utilization statistics (Statistics >Frame Utilization tab: Frame Utilization:
Downlink and Uplink) are not necessarily indicative of overload condition. They show how much the TDD
frame is utilized. High frame utilization depends on:
1. high traffic during busy periods: those statistics will be close to 100% and almost all slots will be
utilized. In this case if the Overload statistics show that packets are discarded then this is an
indication of overload condition.
2. high percentage of VCs with low modulation with moderate traffic. Those VCs will require more slots
to service them (due to low modulation) and the frame utilization will be high. In this case the TDD
frame is fully utilized but the system is at low capacity and is not in an overload condition.
450m has higher PPS than 450 and 450i and supports higher throughput through spatial multiplexing,
therefore when a 450m replaces an overloaded 450 or 450i AP the 450m will not be overloaded under the
same conditions but the frame utilization may still show close to 100%; this should not alarm the
customer. The overload statistics shall be monitored on 450m to see if it is overloaded or not.

RSSI
Radio Signal Strength Indicator. A relative measure of the strength of a
received signal. An acceptable link displays an RSSI value of greater
than 700.
Self-interference
Interference with a module from another module in the same network.
SFP
Small Form-factor Pluggable
Simple Network
Management Protocol
Standard that is used for communications between a program (agent) in
the network and a network management station (monitor). Defined in
RFC 1157. See http://www.faqs.org/rfcs/rfc1157.html.
SM
Customer premises equipment (CPE) device that extends network or
Internet services by communication with an Access Point Module or an
Access Point cluster.
SNMP
See Simple Network Management Protocol, defined in RFC 1157.
SNMPv3
SNMP version 3
SNMP Trap
Capture of information that informs the network monitor through Simple
Network Management Protocol of a monitored occurrence in the module.
Static IP Address
Assignment
Assignment of Internet Protocol address that can be changed only
manually. Thus static IP address assignment requires more configuration
time and consumes more of the available IP addresses than DHCP
address assignment does. RFC 2050 provides guidelines for the static
allocation of IP addresses. See http://www.faqs.org/rfcs/rfc2050.html.
See also DHCP.

Subnet Mask
32-bit binary number that filters an IP address to reveal what part
identifies the network and what part identifies the host. The number of
subnet mask bits that are set to 1 indicates how many leading bits of the
IP address identify the network. The number of subnet mask bits that are
set 0 indicate how many trailing bits of the IP address identify the host.
Subscriber Module
Customer premises equipment (CPE) device that extends network or
Internet services by communication with an Access Point Module or an
Access Point cluster.
Sustained Data Rate
Preset rate limit of data transfer.
Switch
Network element that uses the port that is associated with the physical
address of another to pass data to only the intended recipient. Compare
to Bridge and Router.
Sync
GPS (Global Positioning System) absolute time, which is passed from
one module to another. Sync enables timing that prevents modules from
transmitting or receiving interference. Sync also provides correlative time
stamps for troubleshooting efforts.
TCP
Alternatively known as Transmission Control Protocol or Transport
Control Protocol. The Transport Layer in the TCP/IP protocol stack. This
protocol is applied to assure that data packets arrive at the target
network element and to control the flow of data through the Internet.
Defined in RFC 793. See http://www.faqs.org/rfcs/rfc793.html.
TDD
Time Division Duplexing. Synchronized data transmission with some
time slots allocated to devices transmitting on the uplink and some to the
device transmitting on the downlink.
telnet
Utility that allows a client computer to update a server. A firewall can
prevent the use of the telnet utility to breach the security of the server.
See http://www.faqs.org/rfcs/rfc818.html,
http://www.faqs.org/rfcs/rfc854.html and
http://www.faqs.org/rfcs/rfc855.html.
Tokens
Theoretical amounts of data. See also Buckets.
TxUnderrun Field
This field displays how many transmission-underrun errors occurred on
the Ethernet controller.
UDP
User Datagram Protocol. A set of Network, Transport, and Session Layer
protocols that RFC 768 defines. These protocols include checksum and
address information but does not retransmit data or process any errors.
See http://www.faqs.org/rfcs/rfc768.html.
udp
User-defined type of port.

U-NII
Unlicensed National Information Infrastructure radio frequency band, in
the 5.1GHz through 5.8 GHz ranges.
VID
VLAN identifier. See also VLAN.
VLAN
Virtual local area network. An association of devices through software
that contains broadcast traffic, as routers would, but in the switch-level
protocol.
VPN
Virtual private network for communication over a public network.
One typical use is to connect remote employees, who are at home or in a
different city, to their corporate network over the Internet. Any of several
VPN implementation schemes is possible. SMs support L2TP over IPSec
(Level 2 Tunneling Protocol over IP Security) VPNs and PPTP (Point to
Point Tunneling Protocol) VPNs, regardless of whether the Network
Address Translation (NAT) feature enabled.
