      DESCRIPTION
         "This trap indicates that a bundle link mismatch has
          been detected.  The following objects are reported:

          mfrBundleNearEndName:    configured name of near end bundle

          mfrBundleFarEndName:     previously reported name of
                                far end bundle

          mfrBundleLinkNearEndName: configured name of near end bundle

          mfrBundleLinkFarEndName: reported name of far end bundle

          mfrBundleLinkFarEndBundleName: currently reported name of
                                far end bundle

          Note: that the configured items may have been configured
                automatically.

          Note: The mfrBundleLinkMismatch counter is incremented when
                the trap is sent."

6.  Security Considerations

   There are a number of management objects defined in this MIB that
   have a MAX-ACCESS clause of read-write and/or read-create.  Such
   objects may be considered sensitive or vulnerable in some network
   environments.  The support for SET operations in a non-secure
   environment without proper protection can have a negative effect on
   network operations.

   No managed objects in this MIB contain sensitive information.

   SNMPv1 by itself is not a secure environment.  Even if the network
   itself is secure (for example by using IPSec), even then, there is no
   control as to who on the secure network is allowed to access and
   GET/SET (read/change/create/delete) the objects in this MIB.

   It is recommended that the implementers consider the security
   features as provided by the SNMPv3 framework.  Specifically, the use
   of the User-based Security Model RFC 2574 [RFC2574] and the View-
   based Access Control Model RFC 2575 [RFC2575] is recommended.

   It is then a customer/user responsibility to ensure that the SNMP
   entity giving access to an instance of this MIB, is properly
   configured to give access to the objects only to those principals
   (users) that have legitimate rights to indeed GET or SET
   (change/create/delete) them.
