Indicates if the unit is undergoing alignment. NB: a 
change of state during operation may generate an SNMP 
trap and/or SMTP email alert

The unit is out of calibration

Encryption has been enabled on one end of the wireless 
link but not the other

The SNMP ifAdminStatus of the data Ethernet interface 
has disabled Ethernet traffic

If the fiber interface on the data Ethernet port is not 
OK, there are three possible causes: 1) the fiber 
interface has been installed but disabled, 2) the 
interface 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 
interface is disabled at the other end of the fiber 
link), or 3) the interface could not be established and 
LOS is detected (i.e. no optical carrier is detected). 
NB: a change of status may generate an SNMP trap and/or 
SMTP email alert

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

Indicates a mismatch of software versions at the two 
ends of the wireless link

If SNTP Sync fails then check the server settings in the 
Remote Management page, or disable SNTP. NB: a change of 
state may generate an SNMP trap and/or SMTP email alert

Current status of the out-of-band management Ethernet 
link

The SNMP ifAdminStatus of the out-of-band management 
Ethernet interface has disabled Ethernet traffic

Current status of the RFU. A state of 'ok' indicates 
that the RFU is fully operational, although may not be 
transmitting.

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

Current status of the wireless link

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

In a 1+1 Hot Standby configuration, the Protection 
Availability Status attribute indicates whether the 
Active unit is currently being protected by the Inactive 
unit. If it isn't being protected, the Active unit will 
report Not Protected and the Inactive unit will report 
Not Protecting.

In a 1+1 Hot Standby configuration, this attribute will 
indicate whether the configuration will support 
protection.

In a 1+1 Hot Standby configuration, only one CMU / RFU 
at a given end of the link is Active at any one time, the 
neighbor CMU / RFU being Inactive. The Protection State 
attribute indicates whether a CMU / RFU is in the Active 
or Inactive state.

The Wireless Receive Signal Status indicates if the 
receiver is able to demodulate the transmit signal from 
the remote end of the link. If it cannot demodulate the 
signal, a protection switch may occur in a system 
configured for 1+1 Hot Standby.

In a 1+1 Hot Standby configuration, the Licensed 
Transmit Capacity Status attribute indicates when the 
Licensed Transmit Capacity is below that of its 
neighbor.

In a 1+1 Hot Standby configuration, the Data Port 
Ethernet Speed Status attribute indicates if the Ethernet 
Speed of the Data Port is below that of its neighbor.

In a 1+1 Hot Standby configuration, the Management Port 
Ethernet Speed Status attribute indicates if the Ethernet 
Speed of the Management Port is below that of its 
neighbor.

In a 1+1 Hot Standby configuration, information is 
shared between neighbor CMUs over the Protection 
Interface. The Protection Interface Status attribute 
reports whether the neighbor CMU is successfully 
responding, physically disconnected or whether it is 
physically connected but not responding, e.g. powered 
down.

The syslog service has been enabled or disabled

The syslog local log is nearly full (90%)

The syslog local log has wrapped

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.

The End Wireless Receive Signal Status indicates if the 
end of a link is unable to demodulate the signal 
transmitted from the remote end of the link. When 
Protection is set to 1+1 Hot Standby, this attribute will 
indicate Not Detected if the Active CMU is unable to 
demodulate the wireless signal. When Receive Diversity is 
enabled, this attribute will indicate Not Detected if 
both the Active and Inactive CMUs are unable to 
demodulate the wireless signal.

When Receive Diversity is enabled, the Inactive CMU 
sends Rx Diversity Ethernet Frames to the Active CMU. 
Before sending these frames, the Data Port MUST be 
negotiated at 1000 Mbps. This attribute indicates if this 
is not the case

The Rx Diversity Availability Status attribute will 
indicate when Receive Diversity is not operating 
correctly, either due to a fault or due to an incorrect 
configuration

For Receive Diversity to operate correctly, certain 
attributes must be configured correctly on both neighbor 
CMUs. The Rx Diversity Configuration Status attribute 
will indicate when this is not the case

IRFU power button have been pressed, IFRU has powered 
down unexpectedly

Enable or disable the syslog client

Signaling was received with the wrong Link Name. Either 
the Link Name is configured differently at each end of 
the wireless link, or this unit is aligned to the wrong 
link partner. NB: A change of value during operation may 
generate an SNMP trap and/or SMTP email alert
