### Unexpected PDUs (cGtpHistUnexpectedMsgs)

Number of unexpected protocol data unit (PDU) messages received.

This object is incremented each time the gateway GPRS support node (GGSN) receives a GPRS Tunneling Protocol (GTP) PDU message for a nonexistent Packet Data Protocol (PDP) context.

### Dropped PDUs (cGtpHistDroppedDataMsgs)

Number of GTP PDU messages dropped for a specific serving GPRS support node (SGSN) path.

### PDUs Received (cGtpHistRcvdPDUMsgs)

Number of PDU messages received on a SGSN path.

### PDUs Sent (cGtpHistSentPDUMsgs)

Number of PDU messages sent on a SGSN path.

### PDU Octets Received (cGtpHistRcvdPDUOctets)

Number of bytes received in a PDU message on a SGSN path.

### PDU Octets Sent (cGtpHistSentPDUOctets)

Number of bytes sent in a PDU message on a SGSN path.

### Too Short PDUs (cGtpHistMsgTooShort)

Number of GTP-PDU messages received which are too short to hold the GTP header for the supported GTP version.

### Unknown Messages (cGtpHistUnknownMsgs)

Number of unknown GTP messages received.

This object is incremented each time a message with a Message Type value that defines an unknown GTP signaling message is received.
