This MIB is an extension to the CISCO-CDMA-PDSN-MIB. A CDMA network supports wireless data communication through 3G CDMA radio access technology and 3G A10/A11 interface. PDSN acts as a foreign agent that establishes, maintains and terminates the link layer to a mobile station. The high level architecture of a third generation CDMA network is shown below: +========+=+ +====+ +=======+ | RAdio |P| | | Data | Home | | Network|C|==A10/A11==|PDSN|===Core=|Network| | (RAN) |F| Interface | |Network | | +========+=+ +====+ (DCN)+=======+ /|\ Foreign Agent Home Agent | (FA) (HA) | Visited Access | Provider Network | \|/ +========+ | Mobile | | Station| | (MS) | +========+ The following diagram illustrates protocols usage by the CDMA network elements: MS=== RAN=== PDSN === DCN == Home Network | | A10/A11 | | | +=signaling==+ | | | | | +...L2TP/L2F | tunnelling..+ | | | +======== PPP ========+ | | | | | +..Mobile IP | tunnelling.. + | | | | | | +=================Mobile IP===========+ | | | | +======================data===========+ The CDMA PDSN EXTENSION MIB provides operational information for a CDMA PDSN implementation. The following areas are managed: 1) Global PDSN information. This area contains generic information such as the number of auxiliary connections per session, PDSN IpAddress, system bandwidth etc. 2) PDSN session information. This area contains details about PPP sessions maintained by the PDSN router and other related information such as flows or PCF. 3) Failure notification. This area contains details of notifications sent to network management applications in case of session creation failure. Acronyms and terms: A10/A11 A10 interface is a virtual interface interface used for transporting data between the RAN and the PDSN. A11 interface is the signaling protocol used for maintaining a logical connection between the RAN and PDSN.
