Appendix A - Event Logs

The IOLINK router generates event logs for various functions performed by the bridge/router. All of the event logs are stored in the internal event log file, which is accessible through the Network Events menu.

Certain event logs are classified as alarms because they are deemed to be of higher urgency. Alarm logs are indicated by an asterisk (“* ”) at the start of the alarm text and are printed on the ALARM line on the menu system as well as being stored in the event log. Alarms are listed in the second part of this appendix.

All WAN-link-related events include the link number in the event log. All remote site-related events include the remote site alias in the event log.

All LCP events are either link based or remote site based depending on whether frame relay is disabled or enabled.

Event logs:

CallerID X callback rejected (not resuming)

Generated when an incoming ISDN call from the specified CallerID has been identified as a request for Callback and has been rejected. The request for Callback was rejected because all available circuits were reserved for resuming connections, while the Callback request was for a new connection.

CallerID X callback rejected (call limit)

Generated when an incoming ISDN call from the specified CallerID has been identified as a request for Callback and has been rejected. The request for Callback was rejected because the CallerID was associated with a remote site whose call limit was exceeded.

CallerID X rejected (not resuming)

Generated when an incoming ISDN call from the specified CallerID has been rejected. The call was rejected because all available circuits were reserved for resuming connections, while the incoming call was for a new connection.

CallerID X rejected (usage limit)

Generated when an incoming ISDN call from the specified CallerID has been rejected. The call was rejected because the CallerID was associated with a remote site whose usage limit was exceeded.

CallerID X security rejection

Generated when a call has been rejected for security reasons. CallerID security is enabled and the incoming CallID does not match any of the numbers configured for any of the remote sites.

Capture off

Generated when link trace capture is turned off.

Client requested address X. No previous record stored.

Generated when a DHCP IP address request is received from a client and there is no record of that address in the address table.
