After filtering, reestablish dialup time quotas
Once sources of excessive dialing activities have been identified and filtered, you may want to increase
the dialup time quota to allow for normal demand. Enter the following command for the new dialup
quota:
dialup interface quota mins
This will set the quota to mins for the rest of the current day and for subsequent days.
NOTE
When the time quota is reached, phone connections are immediately dropped.
For uninterrupted service, issue the above command before the quota limit is reached.
