CISCO-IKE-FLOW-MIB

        This is a MIB module for monitoring the structures
and status of IPsec control flows based on Internet
Key Exchange protocol. The MIB models standard 
aspects of the IKE protocol.
        
Synopsis
        
This MIB module models status, performance and 
failures of the IKEv1- and IKEv2-based signaling in
IPsec, FC-SP(and similar) protocols. In practice, 
the security protocols such as IPsec, FC-SP and 
CTS use a signaling protocol such as IKE, KINK, 
or some such. A number of characteristics of these
signaling protocols are generic.
The generic attributes and status of signaling 
activity has been modeled in 
CISCO-IPSEC-SIGNALING-MIB. This MIB module augments
CISCO-IPSEC-SIGNALING-MIB with IKE-specific
MIB objects.
(Signaling protocols are also referred to this 
document as 'Control Protocols', since they perform
session control.)
        
History of the MIB
A precursor to this MIB was written by Tivoli and
implemented in IBM Nways routers in 1999. That 
MIB instrumented both IKE(v1) and IPsec in a 
single module. During late 1999, Cisco adopted 
the MIB and together with Tivoli published the 
IPsec Flow Monitor MIB in IETF IPsec WG in 
draft-ietf-ipsec-flow-monitoring-mib-00.txt. 
In 2000, the MIB was Cisco-ized and implemented
this draft as CISCO-IPSEC-FLOW-MONITOR-MIB in 
IOS and VPN3000 platforms.
        
With the evolution of IKEv2, the MIB was modified
and presented to the IPsec WG again in May 2003 
in draft-ietf-ipsec-flow-monitoring-mib-02.txt.
        
This version of the draft is a Cisco-ized version
that culls out the IKE-specific aspects of the
IPsec Flow Monitor MIB. 
        
Overview of MIB
The MIB contains five major groups of objects which 
are used to manage the IKE protocol activity. These 
groups include the global statistics, IKE tunnel 
table, IKE History Group and a notification Group.
        
The tunnel table and the history table have a 
sparse-table relationship with the corresponding
tables in the CISCO-IPSEC-SIGNALING-MIB 
(details in the DESCRIPTION of the respective 
tables). 
        
Acronyms
The following acronyms are used in this document:     
        
Flow, Tunnel:
    An ISAKMP SA can be regarded as representing
    a flow of ISAKMP/IKE traffic. Hence an ISAKMP
    is referred to as a 'Phase 1 Tunnel' in this
    document. 
         
IPsec: 
    Secure IP Protocol 
        
ISAKMP:
    Internet Security Association and Key
    Management Protocol
        
IKE:
    Internet Key Exchange Protocol
        
MM:
    Main Mode - the process of setting up
    a Phase 1 SA to secure the exchanges
    required to setup Phase 2 SAs
        
Phase 2 Tunnel:
    AN instance of a non-ISAKMP SA  bundle in 
    which all the SA share the same proxy 
    identifiers (IDii,IDir) protect the same 
    stream of application traffic.
    Such an SA bundle is termed a 'Phase 2 Tunnel'.
    Note that a Phase 2 tunnel may comprise 
    different SA bundles and different number of 
    SA bundles at different 
    times (due to key refresh).
        
QM:         
    Quick Mode - the process of setting up
    Phase 2 Security Associations using a 
    Phase 1 SA.
        
SA: 
    Security Association (ref: rfc2408).
        
VPN:
    Virtual Private Network.
