tcpNotification12

OID (symbolic): TELDAT-TRAP-TCP-MIB::tcpNotification12

OID (numeric): 1.3.6.1.4.1.2007.1.4.12.2.0.12

Node type: NOTIFICATION-TYPE

Description: Notification of Event TCP.12

Message: '$1:$2 -> $3:$4 drop segment, sequence number $5; NO ACK is present'

Parameters list: $1: tcp12-source-ip-address $2: tcp12-source-tcp-port $3: tcp12-destination-ip-address $4: tcp12-destination-tcp-port $5: tcp12-seq-num

TCP has stopped processing the packet because there is no ACK present in the packet.

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-TCP-MIB::tcpNotification12
snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.2007.1.4.12.2.0.12

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]:49517->[192.168.30.10]:162]:
  DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (180012397) 20 days, 20:02:03.97
  SNMPv2-MIB::snmpTrapOID.0 = OID: TELDAT-TRAP-TCP-MIB::tcpNotification12

Start monitoring Teldat router (TCP checksum/connection anomaly event traps) with a free 30-day trial of IPNetwork Monitor. Create custom SNMP monitor using the TELDAT-TRAP-TCP-MIB::tcpNotification12 OID value, configure state conditions and alerts, and monitor any Teldat router (TCP checksum/connection anomaly event traps) from a single console.
