CISCO-TAP-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.

        source IP Address, the protocol (UDP), and the source and
        destination ports from the call control exchange and list all
        necessary information.

        The first index indicates which Mediation Device the

        "The ifIndex value of the interface over which traffic to be

        and it is other than -1 or 0, all traffic on the selected
        interface will be chosen.

        If the value is zero, matching traffic may be received or
        transmitted on any interface.  Additional selection parameters
        must be selected to limit the scope of traffic intercepted.
        This is most useful on non-routing platforms or on intercepts
        placed elsewhere than a subscriber interface.

        If the value is -1, one or both of
        cTapStreamIpDestinationAddress and cTapStreamIpSourceAddress
        must be specified with prefix length greater than zero.
        Matching traffic on the interface pointed to by ipRouteIfIndex
        or ipCidrRouteIfIndex values associated with those values is
        intercepted, whichever is specified to be more focused than a
        default route.  If routing changes, either by operator action
        or by routing protocol events, the interface will change with
        it. This is primarily intended for use on subscriber interfaces
        and other places where routing is guaranteed to be
        symmetrical.

        In both of these cases, it is possible to have the same packet
        selected for intersection on both its ingress and egress
        interface.  Nonetheless, only one instance of the packet is
        sent to the Mediation Device.

        This value must be set when creating a stream entry, either to
        select an interface, to select all interfaces, or to select the

cTapMIBActive   NOTIFICATION-TYPE
     STATUS     current
     DESCRIPTION
        "This Notification is sent when an intercepting router or
        switch is first capable of intercepting a packet corresponding
        to a configured data stream. If the configured data stream is
        an IP one, the value of the corresponding cTapStreamIpStatus 
        is included in this notification. If the configured data stream
        is an IEEE 802 one, the value of the corresponding 
        cTapStream802Status is included in this notification. 

        This notification may be generated in conjunction with the
        intercept application, which is designed to expect the
        notification to be sent as reliably as possible, e.g., through
        the use of a finite number of retransmissions until
        acknowledged, as and when such mechanisms are available; for
        example, with SNMPv3, this would be an InformRequest.  Filter
