When the routing subsystem ELS component is configured to generate SNMP traps, the following trap is generated. It contains a single varBind containing a text string in one of the two following formats. If ELS timestamping is enabled: hr:min:sec subsys_name.event_num: message_text For example - 09:32:56 IP.008: no rte 9.7.1.8 -> 9.7.4.3 dsc If ELS timestamping is disabled: subsys_name.event_num: message_text For example - IP.008: no rte 9.7.1.8 -> 9.7.4.3 dsc NOTE: The following subsystems cannot have their events sent in SNMP traps (ARP, ICMP, UDP, SNMP and IP (excluding IP access control events)). This restriction is due to the fact that these subsystems are involved in sending an SNMP trap and allowing them could cause an infinite loop in the router software.
