natv2NotificationPoolUsageHigh
Module: NATV2-MIB
OID (symbolic): NATV2-MIB::natv2NotificationPoolUsageHigh
OID (numeric): 1.3.6.1.2.1.234.0.2
Node type: NOTIFICATION-TYPE
Description: This notification is triggered when an address pool's usage becomes greater than or equal to the value of the natv2PoolThresholdUsageHigh object for that pool, unless the notification has been disabled by setting the value of the threshold to -1. It is reported subject to the rate limitation specified by natv2PortMapNotificationInterval.
Address pool usage is calculated as the percentage of the total number of ports allocated to the address pool that are already in use, for the most-mapped protocol at the time the notification is triggered. The two returned objects are members of natv2PoolTable indexed by the NAT instance and pool indices for which the event is being reported. They give the number of port map entries using external addresses configured on the pool for the most-mapped protocol and identify that protocol at the time the notification was triggered.
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> '' NATV2-MIB::natv2NotificationPoolUsageHigh snmptrap -v2c -c public <manager> '' 1.3.6.1.2.1.234.0.2
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:
