The PTP radio has changed wireless channel.
This has been caused by either
i) mandatory radar avoidance,
   a DFS impulsive interference event will also be
   detected,
or
ii) Dynamic Spectrum Optimization, (DSO)
    DSO improves link performance by selecting the
    most appropriate transmit and receive channels
    with the lowest level of interference.

Indicates if the unit is being installed. NB: a change 
of state may generate an SNMP trap and/or SMTP email 
alert

The unit is out of calibration

Current status of the Power Over Ethernet (PoE) output 
of the Aux port

The master and slave units have incompatible regulatory 
bands. NB: Both units must have compatible license keys

Spectrum Management was unable to locate a suitable 
wireless channel to operate on

The SNMP ifAdminStatus of the wireless interface has 
disabled wireless traffic

The detection of Ethernet fragments (runt packets) when 
the link is in full duplex is an indication of an 
auto-negotiation or forced configuration mismatch. This 
alarm is only raised if an Out-of-Band Management Mode 
has been configured.

If the SFP link is not OK, there are five possible 
causes: Either a SFP has been installed but the license 
key does not include SFP fiber support, a fiber link 
could not be established even though no LOS was detected 
(i.e. an optical carrier was detected, which could be due 
to a broken TX fiber, or because the link is disabled at 
the fiber link partner), a fiber link could not be 
established and LOS is detected (i.e. no optical carrier 
is detected), the installed SFP is not supported or the 
installed SFP failed to initialize correctly. NB: a 
change of status may generate an SNMP trap and/or SMTP 
email alert

Current status of the SFP Ethernet link. NB: a change of 
state may generate an SNMP trap and/or SMTP email alert

DFS impulsive interference detected event

A non-zero value indicates that the master and slave 
ends of a link are different hardware products, or have 
different software versions, or have different TDD Frame 
Configuraton Modes (Standard/Expert) in HCMP topology. 
NB: It is very unusual to detect this, because 
incompatible units will normally fail to establish a 
wireless link. However, some combinations may establish a 
partial wireless link and detect this situation. NB: A 
non-zero value may generate an SNMP trap and/or SMTP 
email alert

If SNTP Sync fails then check the server settings in the 
Remote Management page, or disable SNTP

Not Synchronized indicates failure of the external 
timing system for a period greater than the holdover 
timer. TDD frame timing will have drifted, and this link 
may cause interference with other links in a synchronized 
network. Timing System Failure is an early warning, 
indicating that 80% of the holdover period has expired.

The SNMP ifAdminStatus of the interface has disabled 
Ethernet traffic

The detection of Ethernet fragments (runt packets) when 
the link is in full duplex is an indication of an 
auto-negotiation or forced configuration mismatch. This 
alarm is only raised if an Out-of-Band Management Mode 
has been configured.

The remote node of this link has been configured with a 
different link mode optimization

@Current status of the connection to the TDM Box. A 
state of 'Up' on a green background indicates that the 
TDM Box is connected OK. When connecting a TDM Box only 
the Main Ethernet port should be used

Current status of the TDM channels. A value of 0 
indicates that a TDM channel is established

The loopback status of TDM channels. This is intended 
for installation testing and should be set to 'None' for 
normal operation. The wire connections to a unit can be 
tested by applying a 'Copper' loopback to the local unit. 
The wireless connection to the remote unit can be tested 
by applying a 'Wireless' loopback to the remote unit with 
no loopback on the local unit. NB: a change of state may 
generate an SNMP trap and/or SMTP email alert

Current status of the NIDU LAN Ethernet link. NB: a 
change of state may generate an SNMP trap and/or SMTP 
email alert

Current status of the Main PSU Ethernet link. NB: a 
change of state may generate an SNMP trap and/or SMTP 
email alert

The syslog service has been enabled or disabled

The syslog local log is nearly full (90%)

The syslog local log has wrapped

Enable or disable the syslog client

The secure mode (e.g. FIPS, UC-APL) state of the unit. 
The secure mode is not configured(1) state indicates that 
the unit is capable of secure mode operation, and one or 
more of the following security materials has not been 
configured: Key Of Keys, Private Key, Public Certificate, 
DRNG Entropy Status, Wireless Encryption Key. The secure 
mode mode is configured but not active(2) state indicates 
that the unit is capable of secure mode operation, and 
the security material has been configured, but the 
configuration of interfaces is not consistent with secure 
mode operation. The secure mode is not supported(3) state 
indicates that the unit is not capable of secure mode 
operation. The secure mode capability requires 
appropriate hardware compatibility, license key and 
software image.

Ethernet Data traffic bridging is disabled because the 
wireless link is not operating at the configured Lowest 
Data Modulation Mode

If the full capability trial license period is about to 
expire then purchase a license upgrade from your 
reseller.

The remote node of this link has a lower link capacity. 
Operating with a reduced effective link capacity.

The measured link range is greater than the maximum 
allowed by the license key. The link will operate at a 
reduced capacity while this condition applies. This alarm 
is only raised if the license specifies a maximum link 
range and the trial license is not active.

Current status of the configuration of the TDM Box. A 
state of 'Ok' on a green background indicates that the 
TDM Box configuration is matched OK with the remote end.

The SNMP ifAdminStatus of the interface has disabled 
Ethernet traffic

The SNMP ifAdminStatus of the interface has disabled

The detection of Ethernet fragments (runt packets) when 
the link is in full duplex is an indication of an 
auto-negotiation or forced configuration mismatch.

The local and remote ODUs have different services 
configured.

Current status of the wireless link. A state of Up on a 
green background indicates that a wireless link is 
established

Listen-Before-Talk (LBT) detected event

Alarm condition indicates that the unit's license is not 
secure enough for FIPS approved mode.

The detection of Ethernet fragments (runt packets) when 
the link is in full duplex is an indication of an 
auto-negotiation or forced configuration mismatch

Current status of the Aux Ethernet link. NB: a change of 
state may generate an SNMP trap and/or SMTP email alert

The SNMP ifAdminStatus of the interface has disabled 
Ethernet traffic

The Regulatory Band prohibits the wireless unit from 
operating outside the regulated limits. An invalid 
Regulatory Band may be caused by a missing or incorrect 
License Key, a corrupt MAC Address or an attempt to 
configure a Regulatory Band not allowed by the License 
Key or an execution of Reset Configuration. NB: a change 
of state may generate an SNMP trap and/or SMTP email 
alert.

A non-zero value indicates that signalling was received 
with the wrong MAC address or a mismatched link name. NB: 
It is very unusual to detect this, because units with 
mis-configured Target MAC Address will normally fail to 
establish a wireless link. However, rare circumstances 
may establish a partial wireless link and detect this 
situation. NB: A non-zero value on start-up, or a change 
of value during operation, may generate an SNMP trap 
and/or SMTP email alert
