Trace Levels
Various levels of tracing are available which provide different levels of messaging.
Emergency, Alert, Critical, Error, Warning, Notice, Info, Debug
Note: All trace modules are set to Error level by default.
Voice quality can potentially be impacted if higher trace levels are configured or if Preserve Logsis enabled, which will
write the logs to flash memory.
In firmware 1.1(1) and later, the trace level will reset to “Error” level by default unless configured to preserve the trace levels.
Radio Status Indicator
As of the 1.3(3) release, the Cisco Unified Wireless IP Phone 7921G can help determine whether the radios is functional or not
by displaying a number of bars for the signal indicator.
The number of bars equates to the signal received by the access point and will display those bars in either grey, yellow or green
depending on the current status.
Below the correlation between the color and status are defined.
Grey The phone is in range of some network, but it may not be in range of the configured network.
This could also be due to a SSID configuration issue.
Yellow The phone has detected it is in range of the configured network and 802.11 band and is attempting to
authenticate to the access point. If the indicator does not move to the green status, then there could be an issue with the
authentication configuration.
Green The phone is currently authenticated to the access point.
