Cisco IOS Dial Technologies Configuration Guide
Local disconnect reasons are listed across the top of the screen display (for example, wdogTimr,
compress, retrain, inacTout, linkFail, moduFail, mnpProto, and lapmProt). In the body of the screen
display, the number of times each modem disconnected is displayed (see the # column). For a particular
disconnect reason, the % column indicates the percent that a modem was logged for the specified
disconnect reason with respect to the entire modem pool for that given reason. For example, out of all
the times the rmtLink error occurred on all the modems in the system, the rmtLink error occurred
10 percent of the time on modem 0/22.
Malfunctioning modems are detected by an unusually high number of disconnect counters for a
particular disconnect reason. For example, if modem 1/0 had a high number of compression errors
compared to the remaining modems in system, modem 1/0 would likely be the inoperable modem.
To reset the counters displayed by the show modem call-stats command, enter the clear modem
counters command.
Note For a complete description of each error field displayed by the commands on this page, refer to the
Cisco IOS Dial Technologies Command Reference. Remote disconnect reasons are not described by
the show modem command output.
The following example displays output for the show modem call-stats command. Because of the screen
size limitation of most terminal screen displays, not all possible disconnect reasons are displayed at one
time. Only the top eight most frequently experienced disconnect reasons are displayed at one time.
