cipUrpfIfDropRateNotify

Module: CISCO-IP-URPF-MIB

OID (symbolic): CISCO-IP-URPF-MIB::cipUrpfIfDropRateNotify

OID (numeric): 1.3.6.1.4.1.9.9.451.0.1

Node type: NOTIFICATION-TYPE

Description: This notification is generated when cipUrpfIfDropRateNotifyEnable is set to true and the calculated URPF drop rate (cipUrpfIfDropRate) exceeds the notification threshold drop rate (cipUrpfIfNotifyDropRateThreshold). Note the exceptional value of 0 for threshold allows notification generation if any drop events occur in an interval.

After generating this notification, another such notification will not be sent out for a minimum of five minutes (note the exception to this provided by cipUrpfIfNotifyDrHoldDownReset).

The object value present in the notification is the the drop rate that exceeded the threshold.

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> '' CISCO-IP-URPF-MIB::cipUrpfIfDropRateNotify
snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.9.9.451.0.1

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:

zoo11-linux.zoo [UDP: [192.168.30.111]:57929->[192.168.30.10]:162]:
