All Implemented Interfaces:
TrapdServiceMBean, org.jboss.kernel.spi.dependency.KernelControllerContextAware, ServiceMBean, MBeanRegistration, NotificationEmitter

MBean wrapper class that acts as an SNMP trap receiver/logger. It logs traps as INFO messages - change log4j configuration to redirect logging output. To reconfigure the listening port the MBean needs to be stopped and re-started.
