SNMP Traps

carOtherAccServerResponding

carOtherAccServerResponding signifies that an accounting server that had previously sent a not responding message is now responding to requests from the Cisco AR server. This trap has three objects:

•radiusAccServerAddress—indicates the identity of the concerned server

•radiusAccClientServerPortNumber—indicates the port number of the concerned server

•carAccServerType—indicates the type of the concerned server

The index of these three objects identifies the entry in radiusAuthServerTable and arAccServerExtTable which maintains the characteristics of the concerned server.

One should not rely on the reception of this notification as an indication that all is well with the network. Several conditions, including the restart of the Cisco AR server, could result in either multiple carOtherAccServerNotResponding notifications being sent or in a carOtherAccServerResponding notification not being sent. The NMS can query the carAccServerRunningState in carAccServerExtTable for the current running state of this server.

carAccountingLoggingFailure

carAccountingLoggingFailure signifies that this Cisco AR server cannot record accounting packets locally. This trap has two objects:

•carNotifAcctLogErrorReason—indicates the reason packets cannot be recorded locally

•carNotifAcctLogErrorInterval—indicates how long to wait until another notification of this type might be sent. A value of 0 (zero) indicates no time interval checking, meaning that no new notification can be sent until the error condition is corrected.

Configuring Traps

Cisco Access Registrar’s SNMP implementation uses various configuration files to configure its applications.

Directories Searched

Configuration files can be found and read from numerous places. By default, SNMP applications look for configuration files in the following three directories (in the order listed):

1./usr/local/share/snmp/snmp.conf

This directory contains common configuration for the agent and the application. Refer to man page snmp.conf(5) for details.

2./usr/local/share/snmp/snmpd.conf

3./usr/local/share/snmp/snmp.local.conf

This directory configures the agent. Refer to man page snmp.conf(5) for details.

In each of these directories, an SNMP application looks for files with the extension .conf. The application also looks for configuration files in default locations where a configuration file can exist for any given configuration file type.
