ESN This field displays the MAC address (electronic serial number) of the BHM.
For operator convenience during BHS aiming, this tab retains each detected
ESN for up to 15 minutes. If the broadcast frequency of a detected BHM
changes during a 15-minute interval in the aiming operation, then a multiple
instance of the same ESN is possible in the list. Eventually, the earlier
instance expires and disappears and the later instance remains to the end of
its interval, but you can ignore the early instance(s) whenever two or more
are present.
Region This field displays the BHM’s configured Country Code setting.
Power Level This field displays the BHS’s combined received power level from the BHM’s
transmission.
Beacon Count A count of the beacons seen in a given time period.
FECEn This field contains the SNMP value from the BHM that indicates whether the
Forward Error Correction feature is enabled.
0: FEC is disabled
1: FEC is enabled
Type Multipoint indicates that the listing is for a BHM.
Age This is a counter for the number of minutes that the BHM has been inactive.
At 15 minutes of inactivity for the BHS, this field is removed from the BHM
Evaluation tab in the BHS.
Lockout This field displays how many times the BHS has been temporarily locked out
of making registration attempts.
RegFail This field displays how many registration attempts by this BHS failed.
Range This field displays the distance in feet for this link. To derive the distance in
meters, multiply the value of this parameter by 0.3048.
MaxRange This field indicates the configured value for the AP’s Max Range parameter.
TxBER A 1 in this field indicates the BHM is sending Radio BER.
Ebcast A 1 in this field indicates the BHM is encrypting broadcast packets. A 0
indicates it is not.
Session Count This field displays how many sessions the BHS has had with the BHM.
Typically, this is the sum of Reg Count and Re-Reg Count. However, the
result of internal calculation may display here as a value that slightly differs
from the sum.
In the case of a multipoint link, if the number of sessions is significantly
greater than the number for other BHS’s, then this may indicate a link
problem or an interference problem.
