cgprsAccPtVerifyUpStrTpduSrcAddr
Cisco GPRS Access Point Verify Up Str Tpdu Source Address
1.3.6.1.4.1.9.9.183.1.1.3.1.5
When this object is set to 'true', the Gateway will check the upstream TPDU source address against the address previously assigned to this user. If the addresses are different, the TPDU is dropped, the notification cgprsAccPtSecSrcViolNotif is generated and cgprsAccPtSourceAddrViolTpdus is incremented. This check will enable the Gateway to restrict the users with fake identity. When the object is set to 'false', no checking is performed by the Gateway.
