CISCO-IPSEC-POLICY-MAP-MIB file content

The SNMP protocol is used to for conveying information and commands between agents and managing entities. SNMP uses the User Datagram Protocol (UDP) as the transport protocol for passing data between managers and agents. The reasons for using UDP for SNMP are, firstly it has low overheads in comparison to TCP, which uses a 3-way hand shake for connection. Secondly, in congested networks, SNMP over TCP is a bad idea because TCP in order to maintain reliability will flood the network with retransmissions.

Management information (MIB) is represented as a collection of managed objects. These objects together form a virtual information base called MIB. An agent may implement many MIBs, but all agents must implement a particular MIB called MIB-II [16]. This standard defines variables for things such as interface statistics (interface speeds, MTU, octets sent, octets received, etc.) as well as various other things pertaining to the system itself (system location, system contact, etc.). The main goal of MIB-II is to provide general TCP/IP management information.

   -- PREFACE:
   -- CISCO-IPSEC-POLICY-MAP-MIB Module is an enterprise
   -- specific appendage to the IPSEC-MONITOR-MIB
   -- that has been proposed to IETF. The only function
   -- of this MIB is to map the dynamically instantiated
   -- protocol structures (tunnels, SAs) to the policy
   -- entities that gave rise to them (policy definitions,
   -- cryptomaps, transforms etc).

   -- RELATIONSHIP TO COMMAND LINE INTERFACE (CLI):
   -- Information contained in all the MIB elements
   -- defined in this module are affected by CLI
   -- operations, EXCEPT where it is explicitly noted
   -- to the contrary.

         DESCRIPTION
                 "The MIB module maps the IPSec
         entities created dynamically to the policy entities
         that caused them. This is an appendix to the
         IPSEC-MONITOR-MIB that has been proposed to
         IETF for monitoring IPSec based Virtual Private 
         Networks.

         Overview of Cisco IPsec Policy Map MIB

         MIB description

         There are two components to this MIB:  
	  #1 a table that maps an IPSec Phase-1 
	     tunnel to the Internet Security Association 
	     and Key Exchange (ISAKMP) Policy 
	     
	  and 

	  #2 a table that maps an IPSec Phase-2 
	     tunnel to the corresponding IPSec Policy
	     element - called 'cryptomaps' - in IOS 
	     (Internet Operating System)

         The first mappin (also called Internet Key Exchange
	 or IKE mapping) yields, given the index of
         the IKE tunnel in the ikeTunnelTable
         (IPSEC-MONITOR-MIB), the ISAKMP policy definition
         defined using the CLI on the managed entity.

         The IPSec mapping yields, given the index
         of the IPSec tunnel in the ipSecTunnelTable
         (IPSEC-MONITOR-MIB), the IPSec transform and
         the cryptomap definition that gave rise to
         this tunnel.

         In implementation and usage, this MIB cannot
         exist independent of the IPSEC-MONITOR-MIB. "

	  The ACL that causes an IPSec tunnel
	  to be established is referenced by the 
	  cryptomap of the tunnel.

	  The ACL identifies the traffic that requires
	  protection as defined by the policy.

	  For instance, the ACL that requires FTP
	  traffic between local subnet 172.16.14.0 and a
	  remote subnet 172.16.16.0 to be protected
	  is defined as

	   ==> ip access-list standard myAcl

       DESCRIPTION
          "The value of this object is the access control 
	  entry (ACE) within the ACL that caused this IPSec 
	  tunnel to be established. 

	  For instance, if an ACL defines access for two
	  traffic streams (FTP and SNMP) as follows:
	  
           access-list 101 permit tcp 172.16.14.0 0.0.0.255

          When associated with an IPSec policy, the second
	  element of the ACL gives rise to an IPSec tunnel
	  in the wake of SNMP traffic. The value of the
	  object 'ipSecPolMapAceString' for the IPSec tunnel
	  would be then the string
           'access-list 101 permit udp 172.16.14.0 0.0.0.255
