Description: Covers the ITP global SS7 routing table used to determine destination point code reachability.

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-GRT-MIB?

CISCO-ITP-GRT-MIB manages the Global Routing Table (GRT) used by Cisco's IP Transfer Point (ITP) to determine SS7 destination point code reachability over an IP-based signaling network. It exposes configuration for dynamic-routing limits and notification throttling (delay, window, and max-per-window settings for destination and management events), plus operational counters for dynamic routes learned and dropped. This is primarily a routing/fault-monitoring MIB: administrators watch cgrtDynamicRoutesDropped and route-table-load notifications to detect SS7 reachability problems or route-table overflow that could indicate signaling network instability. It is grounded in ITU-T Q-series SS7 standards for signaling point routing. It is deployed on Cisco ITP nodes functioning as SS7 signaling points/route servers in carrier networks. Engineers can download the CISCO-ITP-GRT-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-ITP-GRT-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.

Supported Devices

Cisco IP Transfer Point (ITP) SS7 signaling routers

Monitoring Examples

An operator can compare cgrtDynamicRoutes against cgrtRouteMaxDynamic to see how close the dynamic route table is to capacity, and watch cgrtDynamicRoutesDropped for evidence that routes are being rejected because the table is full. Enabling cgrtDestNotifEnabled and cgrtMgmtNotifEnabled with their delay/window/max settings lets the ITP throttle and emit notifications on reachability or management events, and cgrtRouteTableLoadNotifEnabled signals when the full route table has been (re)loaded, e.g. after a restart.

What Can Be Monitored

dynamic routes learned/dropped
dynamic route table capacity usage
destination reachability notifications
route table load events
notification throttling configuration

How to Use in IPNetwork Monitor

Example using cgrtDynamicRoutesDropped 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 cgrtDynamicRoutesDropped into the Find box to locate it in the OID tree, then select it and click OK. The number of dynamic route entries that could not be created because the limit specified by the cgrtRouteMaxDynamic object had been reached. 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, 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.

ciscoGrtMIB	1.3.6.1.4.1.9.9.334			This MIB is for managing information required to route messages transported over Signalling System No. 7 (SS7) Network via Cisco IP Transfer Point. The Cisco IP Transfer Point (ITP) is a hardware and software solution that transports SS7 traffic using IP. Each ITP node provides the functions necessary to act as a SS7 signalling point. Each signalling point is connected to other signalling point using IP based or traditional TDM links. The relevant ITU documents describing this technology are the ITU Q series, including ITU Q.700: Introduction to CCITT Signalling System No. 7 and ITU Q.701 Functional description of the message transfer part (MTP) of Signalling System No. 7. Definitions and overview: Route: A route consists of one or more linksets used to transport MTP3 Message Signal Units(MSU) between signalling points. A route is an association between a destination point code(DPC) and a linkset, i.e., a linkset that can be used to send an MSU to the given DPC. Routeset: A routeset is a set of routes to a given DPC. Each route within a routeset is on a possible path toward the DPC. Each route within the routeset has associated with it a route priority. In the following simple configuration, two routes exist that can be used to transport MSUs from STP1 to STP4. --------- STP1-STP2 --------- - STP1 ----------------------------- STP2 - --------- --------- \| \| \| STP1-STP3 STP2-STP4 \| \| \| --------- STP3-STP4 --------- - STP3 ----------------------------- STP4 - --------- --------- Routeset on STP1 for DPC = STP4: STP1-STP2, STP1-STP3 Linkset: A linkset is a set of signalling links connecting two signalling points. Combined Linkset: Two linksets with equal number of links and capacity that form routes of equal priority to a given DPC are called Combined Linksets. It is primarily used for load sharing and redundancy. In the following, example, linksets 'SSP1-STP1' and 'SSP1-STP2' form a combined linsket. SSP1-STP1 --------- \|------------------------- STP1 - \| --------- - - - - - SSP1 - - - - - \| SSP1-STP2 --------- \|------------------------ STP2 - --------- Routing: The routing of SS7 Message signalling Units(MSU) is based on the DPC. Message Signalling Units are sent from an originating point code(OPC) to DPC. Each MSU will traverse one or more linksets as it is routed to its final destination. When an MSU arrives at a signalling point and the DPC does not match the signalling point's point code the MSU must be directed toward the DPC. Each signalling point has enough routing information to determine which linkset should be used to transmit the MSU toward its final destination. Route statement: Each ITP Signalling Point has route statements needed to determine which linkset should be used to transmit message signalling units to destinations. Each route statement consists of a destination, a priority and a linkset name. The destination is specified as a combination of DPC and mask. The priority, also know as cost, is used to define the order in which the routes are selected. The linkset name specifies which linkset to use to reach the destination. Route table: Each ITP Signalling Point has a table of routes. These route entries are used to determine which linkset should be selected to transmit message signalling units to a given destination. There are two basic type of routing. The first type is fully-qualified and uses all bits of the target DPC. The other type is summary routing that uses a subset of the bits in the target DPC and is used to represent groups of point codes rather than a single point code. Example of route table entries. Example 1: variant = ITU DPC/MASK Priority Linkset-name -------- -------- ----------------------- 5.5.5/14 3 STP1-STP2 5.5.5/14 7 STP1-STP3 Description: Two route table entries that define a primary route using linkset 'STP1-STP2' and an alternate route using linkset 'STP1-STP3' to point-code 5.5.5. Example 2: variant = ITU DPC/MASK Priority Linkset-name -------- -------- ----------------------- 5.5.5/14 3 STP1-STP2 5.5.5/14 3 STP1-STP3 5.5.5/14 7 STP1-STP4 Description: Two route table entries that define a combined linkset consisting of linkset 'STP1-STP2' and 'STP1-STP3' to point code 5.5.5. An alternate route is also defined using linkset 'STP1-STP4'. Example 3: variant = ANSI DPC/MASK Priority Linkset-name -------- -------- ----------------------- 5.5.0/16 3 STP1-STP2 Description: A route table entry that defines routing to a cluster. The cluster represents all point codes in the range from 5.5.0-5.5.255. Example 4: variant = ANSI DPC/MASK Priority Linkset-name -------- -------- ----------------------- 5.5.0/16 3 STP1-STP3 5.5.5/24 3 STP1-STP2 Description: The mixing of fully-qualified and summary route table entries allow for different routes to be defined for certain DPC in a cluster. In this configuration, the fully-qualified route will be the primary and the summary route will act as a backup. Route table: A group of route table entries used to route MSU for a particular instance of a signalling point. A sample route table. DPC/MASK Priority Linkset-name -------- -------- ----------------------- 0.0.0/0 7 STP1-STP4 5.5.0/16 3 STP1-STP3 5.5.5/24 3 STP1-STP2 . . 122.5.5 5 STP1-STP2 . . 243.200.1 6 STP1-STP3
