Access Point Identifier (cgprsAccPtIndex)

Unique local identifier for the access point on the GGSN.


Access Point List In Enable (cgprsAccPtIPAccListInEnable)

When set to true, ACL denoted by cgprsAccPtIPAccListGroupIn becomes active. When set to false, it becomes inactive.


Access Point List Out Enable (cgprsAccPtIPAccListOutEnable)

When set to true, ACL denoted by cgprsAccPtIPAccListGroupOut becomes active. When set to false, it becomes inactive.


RADIUS accounting server response Enable (cgprsAccPtGtpRespMesgWaitAcctng)

When set to true, GGSN waits for a RADIUS accounting response before sending a create PDP context response to the SGSN, for create PDP context requests received at a particular APN.

When set to false, GGSN sends create PDP response to SGSN after sending a RADIUS start accounting message to the RADIUS server (without waiting for a response from the RADIUS accounting server).


Radius Attribute Status (cgprsAccPtImsiSuppressed)

Specifies whether GGSN will send the radius attribute (IMSI value) in any of the radius requests to the radius server.

When set to true, the IMSI attribute will not be sent by the GGSN.

When set to false, the IMSI attribute will be sent by the GGSN.

This object is deprecated by cgprsAccPtSuppressRadiusAttribs.


TPDU Source Address Verification (cgprsAccPtVerifyUpStrTpduSrcAddr)

When set to true, GGSN checks the upstream TPDU source address against the address previously assigned to this user. If the addresses are different, the TPDU is dropped and cgprsAccPtSourceAddrViolTpdus is incremented. This check enables GGSN to restrict users with fake identity.

When set to false, no checking is performed by GGSN.


TPDU Destination Address Verification (cgprsAccPtVerifyUpStrTpduDstAddr)

When set to true, GGSN checks the upstream TPDU destination address against the range of IP addresses reserved for PLMN devices. If there is a match, the TPDU is dropped and cgprsAccPtDestAddrViolTpdus is incremented. The configuration of IP address ranges reserved for PLMN device is out of the scope of this MIB. This check would enable GGSN to protect GPRS network from some hacker who may try to flood the GGSN and PLMN nodes with intense data traffic.

When set to false, no checking is performed by GGSN.


Inter Mobile Address Type (cgprsAccPtRedirInterMobilAddrTyp)

Type of Internet address by which cgprsAccPtRedirInterMobilAddr is reachable.


Inter Mobile Address (cgprsAccPtRedirInterMobilAddr)

IP address of the device to which inter-mobile traffic is redirected. When this redirection is active on an APN, before downstream packets exit GGSN, they are screened to see if they come from other GTP tunnels. If so, they are not GTP-tunneled downstream, but get redirected to the device. When set to zero, inter-mobile traffic is not redirected (that is., the traffic gets switched through GGSN without going through any Gi interface).


Radius Server Request Suppressed (cgprsAccPtSuppressRadiusAttribs)

Attributes that are suppressed by GGSN in its authorization and accounting requests to the RADIUS server.


Enable AAA Interim Accounting (cgprsAccPtInterimAccountinEnable)

When set to true, AAA interim accounting for PDP contexts on this APN is enabled and accounting updates are triggered whenever a update PDP request is received. This object can be set to true only when cgprsAccPtAaaAccountingEnable is already enabled.


Radius Attribute Values (cgprsAccPtSetRadiusAttributes)

Indicates the values set in various radius attributes by the GGSN while communicating with the RADIUS Server. There are three possible values:

none: Resets the value set by the following options.

userNameMsisdn - The MSISDN of the mobile node is sent in the user-name attribute.

accSessIdChargingId - The Charging ID is sent in the accounting session id attribute.


Service Mode (cgprsAccPtOperationMode)

Indicates the current operational mode of this APN. There are two possible values:

inService: Normal operational mode in which all functions are allowed. A cgprsAccPtInServiceNotif notification is sent to indicate the state change.

maintenance: No new PDP contexts can be activated in this mode. A cgprsAccPtMaintenanceNotif notification is sent to indicate the state change.


Absolute Session Timer (cgprsAccPtAbsoluteSessionTimer)

When the time interval specified by this object expires, the GGSN deactivates the PDP. A value of zero for this object indicates that the timer is disabled.


NAS Id (cgprsAccPtRadiusAttrNasId)

Value used as the NAS ID in RADIUS access requests sent by the GGSN on this APN.

Note: To clear this value, set a zero-length string for this object.


Inbound Service Policy (cgprsAccPtPdpInServicePolicyName)

Name of the service policy that is applicable to inbound traffic on all PDP contexts associated with this APN.


Verify Domain (cgprsAccPtPppRegenVerifyDomain)

When set to true, a PPP regeneration session creation request is rejected if the domain name specified in the PCO field is different from the APN name. This object can be set only when cgprsAccPtPppRegenEnable is set to true.


Local Address Pool Name (cgprsAccPtIpAddrLocalPoolName)

Name of the local address pool used when cgprsAccPtIpAddressPool is set to local.


Service-Aware Billing (cgprsAccPtServiceAware)

Enables service-aware billing (Diameter Credit Control Application [DCCA] support) on the access-point. This object can be set only when the object cGgsnSAServiceAware present in CISCO-GGSN-SERVICE-AWARE-MIB is set to 'true'.

Note: This object is available for  GGSN version 6.0 and later.


Downlink Next Hop Address Type (cgprsAccPtAdvDownlinkNextHopAddrType)

Type of Internet address of downlink next hop address.

Note: This object is available for  GGSN version 6.0 and later.


Downlink Next Hop Address (cgprsAccPtAdvDownlinkNextHopAddr)

Advertises the next hop address on the GGSN to which downlink traffic destined for the GGSN is to be routed. The address type is given by the cgprsAccPtAdvDownlinkNextHopAddrType object.

Note: This object is available for  GGSN version 6.0 and later.
