You can use this report as the central starting point to improve uptime by multiple criteria. This report covers
protocol-oriented, device-oriented, or SSID-oriented information. This report can help to monitor and optimize
the network in multiple ways. It can demonstrate service parameters, can establish locations that have superior or
problematic uptime availability, and can help with additional analysis in multiple ways. Locations, device groups,
or other groupings within a network can be identified as needing attention or can be proven to have superior
performance when using this report.
As of AirWave 7.4, the Device Uptime Report contains four new columns that track bootstrap count (number of
times the device has gone down for a firmware change), reboot count, downtime duration, and downtime
duration percent. As mentioned above, you can optionally ignore device downtime during planned maintenance
periods in this report, and you can restrict the report to business days only.
Figure 170 and Table 131 illustrate and describe the Device Uptime report.

Field Description
SNMP Uptime Displays the percentage of time the device was reachable via ICMP. AirWave polls the device via
SNMP at the rate specified on the Groups > Basic page.
ICMP Uptime Displays the percentage of time the device was reachable via ICMP. If the device is reachable via
SNMP it is assumed to be reachable via ICMP. AirWave only pings the device if SNMP fails and then it
pings at the SNMP polling interval rate.
Time Since Last Boot The uptime as reported by the device at the end of the time period covered by the report.
