The MIB module for VPDN.

Overview of VPDN MIB

MIB description

This MIB is to support the Virtual Private Dialup Network (VPDN) feature of Cisco IOS. VPDN handles the forwarding of PPP links from an Internet Provider (ISP) to a Home Gateway.

The VPDN MIB provides the operational information on Cisco’s VPDN tunnelling implementation. The following entities are managed: 1) Global VPDN information 2) VPDN tunnel information 3) VPDN tunnel’s user information 4) Failure history per user

The following example configuration shows how the VPDN MIB returns VPDN information, from either CISCO A - Network Access Server (NAS) or CISCO B - Tunnel Server (TS). The User call is projected by either domain name or Dialed Number Identification Service (DNIS).

The terms NAS and TS are generic terms refering to the VPDN systems.

The following table shows the corresponding technology-specific terms.

  1. The VPDN global entry identifies the system wide VPDN information.
  2. The VPDN tunnel table identifies the active VPDN tunnels on Cisco A and Cisco B. The table contains an entry for each active tunnel on the system.
  3. The VPDN tunnel user table identifies the active users for each active tunnel on each system and provides relevant information for each user.
  4. The VPDN failure history table identifies the last failure recorded per user and provides relevant information.
