CISCO-GTP-MIB.mib object view, vendor Cisco

Introduction

Most network devices and programs ship with so-called MIB files to describe the parameters and meanings (i.e.: friendly names) which are available for monitoring via SNMP.
ActiveXperts Network Monitor 2024 can import vendor-specific MIB files, so it can be used to monitor specific OID's (Object Identifiers). This way, you can monitor your devices, computers, etc. by selecting your relevant OID's by name.

ActiveXperts Network Monitor 2024 can import MIB file CISCO-GTP-MIB and use it to monitor vendor specific OID's.

CISCO-GTP-MIB file content

Object view of CISCO-GTP-MIB:

Scalar Object
cGtpGSNService	.1.3.6.1.4.1.9.9.188.1.1.1
This object indicates the type of GPRS service that will be enabled on the device: undefined - the GPRS service functionality is turned off. ggsn - the device will function as a GGSN. sgsn - the device will function as SGSN. gtpdirector - the device will function as GDM. When the device is configured to function as GDM, all the other objects in this MIB will not be accessible and the CISCO-GTP-DIRECTOR-MIB should be used for managing the device.
cGtpVersion	.1.3.6.1.4.1.9.9.188.1.1.2
The highest gtp version supported by the GSN. When the value is, version0 - GTP v0 is supported, version1 - GTP v1 and GTP v0 are supported.
cGtpT3TunnelTimer	.1.3.6.1.4.1.9.9.188.1.1.3
When the GSN behaves as SGSN, the T3-TUNNEL timer is used for mobility management. When a roaming MS moves from one SGSN(Old SGSN) to a another SGSN(New SGSN), this timer is started by the 'Old SGSN'. While the timer is running, the T-PDUs received by the 'Old SGSN' (from the GGSN), and any buffered T-PDUs are forwarded to the 'New SGSN'. When the GSN behaves as GGSN, the GGSN starts this timer after receiving a Update PDP Context request message from 'New SGSN'. An Update PDP context request shall be sent by SGSN as part of mobility management intimating that MS has moved to this SGSN. While the timer is running, the GGSN will not be forwarding any PDUs to the requesting 'New SGSN'.
cGtpT3ResponseTimer	.1.3.6.1.4.1.9.9.188.1.1.4
The T3-RESPONSE timer for retransmission. This timer is started by a GSN, upon the transmission of a signalling request message; it is used for message retransmission purposes, in the event that no response is received by the time the timer expires.
cGtpN3Request	.1.3.6.1.4.1.9.9.188.1.1.5
Maximum number of retransmissions for a signalling request message if no corresponding response message is received for a request in cGtpT3ResponseTimer time.
cGtpN3BufferSize	.1.3.6.1.4.1.9.9.188.1.1.6
Maximum size of the receive buffer for G-PDUs and signalling request messages. If a packet arrives with more data bytes than the receive buffer can contain, the packet will be discarded.
cGtpEchoRequestTimerEnable	.1.3.6.1.4.1.9.9.188.1.1.7
This object indicates whether Echo Request timer is used by the GGSN. - true : will enable the Echo Request timer. - false : will disable the Echo Request timer.
cGtpEchoRequestTimer	.1.3.6.1.4.1.9.9.188.1.1.8

This object indicates whether dynamic echo timer is used by the GGSN. - true : will enable the dynamic echo timer. - false : will disable the dynamic echo timer.
cGtpDynamicEchoTimerMinTime	.1.3.6.1.4.1.9.9.188.1.1.13
This object specifies the minimum time used by the dynamic echo timer. This object should be ignored if cGtpDynamicEchoTimerEnable is set to 'false'.

Table
cGtpGSNTable	.1.3.6.1.4.1.9.9.188.1.2.6
GSN peer table. The SGSN-GGSN peer relationship is established as given in the following series of steps: 1. When Mobile System (MS) wants service, it sends packets to a SGSN with specific APN. 2. SGSN uses the DNS to resolve this APN to the IP address of the GGSN which is the designated as the gateway to this APN. 3. SGSN establishes a path to the GGSN using GTP protocol. 4. The SGSN and GGSN peer maintains path by sending echo request message to each other. If one side fails in echo reply for certain times, the other side will send a notification to NMS. A SGSN can have multiple GGSN as peers, while a GGSN can have multiple SGSN peers, depending on routing path.
cGtpPathTable	.1.3.6.1.4.1.9.9.188.1.2.7
This table identifies the paths established on a GSN. The path may be established between a GGSN and SGSN or GGSN and charging gateway or GGSN and MAP converting GSN. The path between GGSN and charging gateway is established when the charging gateway is configured on the GGSN. The path between GGSN and MAP converting GSN is established when the MAP converting GSN is configured on the GGSN. The path between a GGSN and SGSN is established in the following series of steps: 1. When Mobile System (MS) wants service, it sends packets to a SGSN with specific APN. 2. SGSN uses the DNS to resolve this APN to the IP address of the GGSN which is the designated as the gateway to this APN. 3. SGSN establishes a path to the GGSN using GTP protocol. 4. The SGSN and GGSN peer maintains path by sending echo request message to each other. If one side fails in echo reply for certain times, the other side will send a trap to NMS. A SGSN can have multiple GGSN as peers, while a GGSN can have multiple SGSN peers, depending on routing path. Moreover, a GSN can have more than one path to a peer, each of which will have a unique port.

This notification is sent when one of this GSN's peers failed to respond to the GTP 'Echo Request' message for the waiting interval.
Object Identifier
cGtpMIB	.1.3.6.1.4.1.9.9.188
This MIB module manages the GPRS Tunnelling Protocol (GTP) on GGSN and SGSN. GPRS provides wireless access to packet data network on the GSM infrastructure. The following diagram illustrates a simplified GPRS logical architecture with the name of inter-node interface: +---------------------------------------------+ | +======+ a PLMN | | | SGSN | | | +======+ | | | | | Gn | | | | |+====+ +====+ +=====+ +======+ +======+ | +===+ || TE |-R-| MT |-| BSS |-| SGSN |-Gn-| GGSN |-|-Gi-|PDN| |+====+ +====+ +=====+ +======+ +======+ | +===+ | | | | | | +----------------------------------------|----+ Gp | +-----------------------------+ | +====+ +=====+ +======+ | | | MS |---| BSS |---| SGSN | | | +====+ +=====+ +======+ | | | | other PLMN | +-----------------------------+ GTP is the protocol between GSN nodes (GSN peers) in the GPRS backbone network. It includes both the GTP signalling and data transfer procedures. GTP is used both on the Gn interface, i.e. the interface between GSN peers with in a PLMN, and the Gp interface between GSN peers in different PLMNs. SGSN is the serving GPRS support node, it responsible for the delivery of data packets from and to the MS within its service area. GGSN is the gateway GPRS support node, it provides interworking with external PDN and is connected with SGSNs via an IP-based GPRS backbone network. The GTP protocol is implemented only by SGSNs and GGSN. A PDP Context is an information set maintained by MS and GSNs which describes the mobile wireless service call or session. A Qos Profile is associated with each PDP context which defines multiple attributes like precedence, delay, reliability, peak throughput and mean throughput. Based on the precedence, delay and mean throughput an user is classified into one of the three Qos classes: Best Effort, Normal and Premium. Mean throughput is measured at the Gi and R reference points in units of octets per second. It specifies the average rate at which data is expected to be transferred across the GPRS network during the remaining lifetime of an activated PDP context. A MAP converting GSN is responsible for converting GTP messages to and from MAP messages. This helps in the communication with HLR.
