tunnelUp

Module: IPSEC-TUN-MON-MIB

OID (symbolic): IPSEC-TUN-MON-MIB::tunnelUp

OID (numeric): 1.3.6.1.3.1010.1.2.4.1

Node type: NOTIFICATION-TYPE

Description: The specified tunnel is now up. (In other words, the number of current phase 2 SA suites supporting the tunnel has changed from zero to a non-zero value.)

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> '' IPSEC-TUN-MON-MIB::tunnelUp
snmptrap -v2c -c public <manager> '' 1.3.6.1.3.1010.1.2.4.1

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]:57608->[192.168.30.10]:162]:
  DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (52579080) 6 days, 2:03:10.80
  SNMPv2-MIB::snmpTrapOID.0 = OID: IPSEC-TUN-MON-MIB::tunnelUp

SNMPv3 example:

snmptrap -v3 -l authPriv -u snmpv3user -a SHA -A "AuthPass1" -x AES -X "PrivPass1" <manager> '' IPSEC-TUN-MON-MIB::tunnelUp
