Keep-Alive Trap
Table 7-60: acKeepAlive
Event
acKeepAlive
OID
1.3.6.1.4.1.5003.9.10.1.21.2.0.16
Description
Part of the NAT traversal mechanism. If the device's STUN application
detects a NAT, this trap is sent on a regular time laps - 9/10 of the
acSysSTUNBindingLifeTime object. The AdditionalInfo1 varbind has the
MAC address of the device.
If the device is configured for SNMPv3, the trap is sent with
acBoardTrapGlobalsAdditionalInfo2: SNMPVersion=SNMPv3. If the device is
configured for SNMPv2, the trap is sent with
acBoardTrapGlobalsAdditionalInfo2: SNMPVersion= SNMPv2c.
If the device is also in High-Availability mode (HA) and the active and
redundant devices are synchronized with one another, the trap is sent by
the active device with the acBoardTrapGlobalsAdditionalInfo3 varbind,
which contains the redundant device's serial number (S/N).
Note:
Keep-alive is sent every 9/10 of the time configured by the
[NatBindingDefaultTimeout] parameter.
