Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is CISCO-ITP-MONITOR-MIB?

CISCO-ITP-MONITOR-MIB is a Cisco enterprise MIB for the Cisco ITP (Internet Transfer Point) SS7 signaling gateway platform, managing software-based monitoring sessions that capture SS7 traffic transported over Message Transport Protocol (MTP) links. It exposes connection/session-oriented data in cItpmConnTable, including port numbers, keep-alive settings, congestion onset/abatement thresholds, receive window size, and current queue depth for each monitoring connection. For status monitoring it directly aids software/service health: cItpmConnMonitorState and cItpmConnCongestion report whether a monitoring session is running normally or congested, and cItpmConnQueueDepth against cItpmConnMaxQDepth reveals whether the monitoring collector is falling behind on SS7 message capture. It is inherently tied to SS7/MTP signaling concepts and to the Cisco ITP platform's own link/linkset MIBs for the underlying signaling data being monitored. It is deployed on Cisco ITP signaling gateways in telecom SS7-over-IP environments needing visibility into SS7 traffic-capture sessions, making CISCO-ITP-MONITOR-MIB SNMP monitoring essential for keeping those capture sessions from silently falling behind.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-ITP-MONITOR-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Monitoring Examples

An operator would poll cItpmConnTable to check cItpmConnMonitorState and cItpmConnCongestion for each monitoring connection, along with cItpmConnQueueDepth relative to cItpmConnMaxQDepth. If cItpmConnQueueDepth is climbing toward cItpmConnMaxQDepth while cItpmConnCongestion shows an active congestion state (triggered near cItpmConnCongOnset), that indicates the monitoring session cannot keep up with SS7 message (MSU) volume and may start dropping capture data.

What Can Be Monitored

monitoring session state
connection congestion status
monitoring queue depth vs. max
keep-alive setting
receive window size
congestion onset/abatement thresholds

How to Use in IPNetwork Monitor

Example using cItpmConnCongCounts OID:

Select a Cisco IP Transfer Point (ITP) SS7 signaling gateway (legacy) as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type cItpmConnCongCounts into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. The number of times the connection has entered congestion. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Counter32-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases sharply between polls relative to its normal baseline (in occurences), since an unexpected spike often reflects a real change in traffic or activity. Click Finish to create the monitor; you can adjust any parameter later.

OIDs

OID symbolic	OID numeric	Type	Access	Description
ciscoItpmMIB	1.3.6.1.4.1.9.9.379			The MIB for providing information related to monitoring SS7 links. This information can be used to manage the state of software used to collect all packets transported and received over a SS7 link. Abbreviations: MSU - Message Signalling Unit MTP - Message Transport Protocol SS7 - System No. 7 (SS7) Network
ciscoItpmMIBNotifs	1.3.6.1.4.1.9.9.379.0
NTF ciscoItpMonitorCongestion	1.3.6.1.4.1.9.9.379.0.1			The notification generated when a connection enters or exits congestion state. The value of cItpmConnCongestion indicates new state.
NTF ciscoItpMonitorState	1.3.6.1.4.1.9.9.379.0.2			The notification generated when a connection changes states. The value of cItpmConnMonitorState indicates new state.
ciscoItpmMIBObjects	1.3.6.1.4.1.9.9.379.1
cItpmConn	1.3.6.1.4.1.9.9.379.1.1
cItpmConnTable	1.3.6.1.4.1.9.9.379.1.1.1		not-accessible	This table provides information on connections used to collect information on SS7 links. Information in this table can be used to customize connection parameters. In addition, this table provides measurements and status information for each connection.
cItpmConnTableEntry	1.3.6.1.4.1.9.9.379.1.1.1.1		not-accessible	An entry in the cItpmConnTable table.
INE cItpmConnPortNumber	1.3.6.1.4.1.9.9.379.1.1.1.1.1	InetPortNumber	not-accessible	The port number used to establish TCP connection.
U32 cItpmConnKeepAlive	1.3.6.1.4.1.9.9.379.1.1.1.1.2	Unsigned32	read-write	Specifies the keepalive time value in milliseconds. Keepalive packets are sent between the monitor and the remote server as a mechanism to ensure the TCP session is active and detect session failure in a timely manner. During periods of idle monitor traffic, the monitor will send a keepalive packet to the remote server at the specified interval. The monitor also expects to receive a keepalive packet from the remote server at the same interval. If the monitor does not receive a keepalive packet from the remote server in two times the keep alive value, the monitor will close the TCP session. The value of zero disables the keep alive processing.
U32 cItpmConnMaxQDepth	1.3.6.1.4.1.9.9.379.1.1.1.1.3	Unsigned32	read-write	The maximum number of packets that can be queued for transmission. If the monitor cannot send a TCP packet immediately, the packet will be queued for retransmit. This object defines the maximum number of TCP packets that may be queued for retransmit. Once the number of TCP packets on the queue reaches the value specified by this object, additional TCP packets will be dropped.
U32 cItpmConnCongOnset	1.3.6.1.4.1.9.9.379.1.1.1.1.4	Unsigned32	read-write	Threshold used to mark onset of congestion. When the cItpmConnQueueDepth object reaches value specified by this object the connection will considered congested. It will remain congested until the cItpmConnQueueDepth object drops below the value specified by the cItpmConnCongAbate object.
U32 cItpmConnCongAbate	1.3.6.1.4.1.9.9.379.1.1.1.1.5	Unsigned32	read-write	Threshold used to mark end of congestion. When the cItpmConnQueueDepth object drops below the value specified by this object the connection will exit congestion.
U32 cItpmConnRcvWindowSize	1.3.6.1.4.1.9.9.379.1.1.1.1.6	Unsigned32	read-write	The size of TCP receive window. This object defines the number of outstanding (unacknowledged) bytes that the ITP monitor can receive on TCP connection.
T/F cItpmConnFastStart	1.3.6.1.4.1.9.9.379.1.1.1.1.7	TruthValue	read-write	Defines the fast-start option for establishing TCP connectivity as follows. 'true' - FastStart is enabled. 'false' - FastStart is disabled. Normally, after the TCP session with the remote server is established, the monitor will not send MSUs from the monitored links to the server until the server responds to the first keepalive. This mechanism prevents the ITP from over-running the server until the TCP session and receive window sizes are fully established. Configuration of fast-start overrides this mechanism and allows the ITP to start sending MSUs to the server immediately after the TCP session is established. Caution should be used with the fast-start configuration as MSUs may be lost until the TCP session server and receive window sizes are fully established.
G32 cItpmConnQueueDepth	1.3.6.1.4.1.9.9.379.1.1.1.1.8	Gauge32	read-only	The number of packets queued for transmission. The maximum value is specified by the cItpmConnMaxQDepth object.
INT cItpmConnMonitorState	1.3.6.1.4.1.9.9.379.1.1.1.1.9	INTEGER	read-only	The state of the connection as follows. 'active' - connection is transmitting SS7 link traffic to server. 'inactive' - connection is not transmitting SS7 link traffic to server.
T/F cItpmConnCongestion	1.3.6.1.4.1.9.9.379.1.1.1.1.10	TruthValue	read-only	Congestion indicator for connection as follows. 'true' - connection is congested. 'false' - connection not congested. Congestion onset occurs when the cItpmConnQueueDepth object reaches the maximum allowed value specified by the cItpmConnMaxQDepth object. Congestion abate occurs when the cItpmConnQueueDepth object reaches the maximum allowed value specified by the cItpmConnMaxQDepth object.
C32 cItpmConnCongCountsEx	1.3.6.1.4.1.9.9.379.1.1.1.1.11	Counter32	read-only	The number of times the connection has entered congestion.
cItpmLinkTable	1.3.6.1.4.1.9.9.379.1.1.2		not-accessible	This table provides information and measurements on the monitored SS7 links per connection. This table shares the cItpmConnPortNumber index with the cItpmConnTable.
cItpmLinkTableEntry	1.3.6.1.4.1.9.9.379.1.1.2.1		not-accessible	An entry in the cItpmLinkTable table.
U32 cItpmLinkNumber	1.3.6.1.4.1.9.9.379.1.1.2.1.1	Unsigned32	not-accessible	This object specifies the secondary index for objects in the cItpmLinkTable table. A unique number is assigned to each link when it is assigned to a connection.
STR cItpmLinkDescription	1.3.6.1.4.1.9.9.379.1.1.2.1.2	SnmpAdminString	read-only	Brief customer defined description.
