### Unexpected Messages (cGtpUnexpectedSigMsgs)

Number of unexpected GPRS Tunneling Protocol (GTP) signaling messages received.

This object is incremented each time a message is received on the wrong end of the tunnel or a response message is received for a request that was not sent by the gateway GPRS support node (GGSN).

### Roaming MS PDUs (cGtpRoamingPDUs)

Number of protocol data unit (PDU) messages received from a roaming mobile station (MS) on a serving GPRS support node (SGSN) path.

### Security Violations (cGtpSecurityViolations)

Number of security violations that occurred on each SGSN path.

This object is incremented each time the GGSN receives a packet from an MS with a source or destination address violation.

### Create Requests (cGtpUnsupportedExtHdr)

Number of Packet Data Protocol (PDP) context creation requests received with unsupported extension headers.

### Total Path Failures (cGtpPathFailures)

Number of path failures on the GGSN.

This object is incremented each time the transmit response timer expires for any message sent on the path.

### Packets Dropped (cGtpTotalDropped)

Number of packets dropped by the GGSN.

### Signaling Packets Dropped (cGtpDroppedSigMsgs)

Number of signaling packets dropped by the GGSN.

### GTP Messages Received (cGtpRcvdSigMsgs)

Number of signaling messages received on a SGSN path.
