Trap Generation
SNMP agents also have the ability to send (unrequested) messages to SNMP
managers; these messages are called traps and notify the SNMP managers that an
event has happened on the system. The SNMP Traps generated by the router are:
• coldstart - indicating that the system has be initialized
• warmstart - indicating that the system has be re-initialized (LES EOC only)
• link up - indicating that the WAN link has been established
• link down - indicating the WAN link has been dropped
• insufficient physical bandwidth - indicating the physical layer bandwidth has
dropped below the configured AAL2 VC bandwidth
• excess impairment - indicates the number of impairments on a voice port has
exceeded the CPIWF Impairment threshold
