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. Network Access Server Tunnel Server ------------------------------ ------------------------- L2F Network Access Server (NAS) Home Gateway (HGW) L2TP L2TP Access Concentrator (LAC) L2TP Network Server (LNS) PPTP PPTP Access Concentrator (PAC) PPTP Network Server (PNS) (NAS) (TS) User ===== Cisco A ===== IP Network ===== Cisco B ===== Server | | +========== VPDN ==========+ 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.

Obsoleted the following deprecated L2F specific objects.
These set of objects have been replaced by the
corresponding multi-protocol objects since 1999-03-24.
Obsoleted Objects Existing replacements
================= =====================
cvpdnTunnelTotal cvpdnSystemTable
cvpdnSessionTotal cvpdnSystemTable
cvpdnDeniedUsersTotal cvpdnSystemTable
cvpdnTunnelTable cvpdnTunnelAttrTable
cvpdnTunnelSessionTable cvpdnSessionAttrTable
Deprecated the following objects and added corresponding
InetAddressType/InetAddress compliant counterparts:
Deprecated Objects Added Replacements
================== ==================
cvpdnTunnelAttrLocalIpAddress
cvpdnTunnelAttrLocalInetAddressType
cvpdnTunnelAttrLocalInetAddress
cvpdnTunnelAttrSourceIpAddress
cvpdnTunnelAttrSourceInetAddressType
cvpdnTunnelAttrSourceInetAddress
cvpdnTunnelAttrRemoteIpAddress
cvpdnTunnelAttrRemoteInetAddressType
cvpdnTunnelAttrRemoteInetAddress
cvpdnUnameToFailHistSourceIp
cvpdnUnameToFailHistSourceInetType
cvpdnUnameToFailHistSourceInetAddr
cvpdnUnameToFailHistDestIp
cvpdnUnameToFailHistDestInetType
cvpdnUnameToFailHistDestInetAddr
Added two new values, 'pwUp' and 'pwDown', for the
existing object cvpdnNotifSessionEvent to support
pseudowire status change event reporting.
2004-06-08 00:00
Deprecated the cvpdnBundleEndpointType object since it's
values did not align with the PPP protocol. This object was
replaced by cvpdnBundleEndpointClass.
2004-04-02 00:00
Added support for Multilink PPP VPDN information. Modified
the cvpdnSessionAttrTable to add objects that specify the
multilink PPP bundle to which a session belongs. Added
scalar objects to hold the total number of multilink PPP
bundles comprised of one, two, and more than two links.
Added the cvpdnBundleTable that describes the PPP multilink
bundle. Added the cvpdnChildBundleTable to expose the
containment relationship between the multilink PPP bundle
and the VPDN tunnel.
2002-07-08 00:00
Added support for VPDN Template information. The template
table reports the number of active sessions for each
template. This number is the sum of active sessions for
all VPDN groups associated with each template.
2002-05-17 00:00
Changed cvpdnSessionAttrVirtualCircuitID to an Unsigned32
object. Also, moved Unsigned32 import to SNMPv2-SMI.
2002-04-02 00:00
Added virtual circuit ID, packets dropped, and notification
objects for WAN/IP support.
2000-01-12 00:00
Added support for Point-to-Point Tunneling Protocol (PPTP).
Changed object descriptions to use generic terms.
1999-03-24 00:00
Added support for multiple tunnel protocols with these
tables
1) cvpdnSystemTable
2) cvpdnTunnelAttrTable
3) cvpdnTunnelSessionAttrTable
Deprecated objects and tables duplicated by the three new
tables
1) cvpdnTunnelTotal, cvpdnSessionTotal,
cvpdnDeniedUsersTotal
2) cvpdnTunnelTable
3) cvpdnTunnelSessionTable
