WEB OPERATION & CONFIGURATION
Multicast:
The total number of good packets received that were directed to a multicast address.
CRC Errors:
The total number of packets received that had a length (excluding framing bits, but including FCS octets)
of between 64 and 1518 octets.
Undersize:
The total number of packets received that were less than 64 octets.
Oversize:
The total number of packets received that were longer than 1518 octets.
Frag.:
The number of frames which size is less than 64 octets received with invalid CRC.
Jabb.:
The number of frames which size is larger than 64 octets received with invalid CRC.
Coll.:
The best estimate of the total number of collisions on this Ethernet segment.
Utilization:
The best estimate of the mean physical layer network utilization on this interface during this sampling
interval, in hundredths of a percent.
3.4.4.7 Alarm Overview
ID:
Display an alarm control index.
Interval:
Interval in seconds for sampling and comparing the rising and falling threshold.
Variable:
MIB object that is used to be sampled.
Sample Type:
The method of sampling the selected variable and calculating the value to be compared against the
thresholds.
Value:
The value of the statistic during the last sampling period.
Startup Alarm
: The alarm that may be triggered when this entry is first set to valid.
Rising Threshold:
If the current value is greater than the rising threshold, and the last sample value was less than this
threshold, then an alarm will be generated.
Rising Index
: The index of the event to use if an alarm is triggered by monitored variables crossing above the rising
threshold.
Falling Threshold
: If the current value is less than the falling threshold, and the last sample value was greater than this
threshold, then an alarm will be generated.
Falling Index:
The index of the event to use if an alarm is triggered by monitored variables crossing below the falling
threshold.
