Examples

Send this trap to an SNMP manager — replace <manager> with the IP or hostname of your monitoring server (SNMPv2c):

snmptrap -v2c -c public <manager> '' TELDAT-TRAP-STP-MIB::stpNotification21
snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.2007.1.4.73.2.0.21

Listen for incoming traps on the manager host (-f keeps it in the foreground, -Lo prints to stdout — useful for testing):

snmptrapd -f -Lo -c /dev/null authCommunity log public

Example snmptrapd log entry:
