CISCO-TAP-MIB device MIB details by Cisco
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.

The same data stream may be required by multiple taps, and one might assume that often the intercepted stream is a small subset of the traffic that could be intercepted. This essentially provides options for packet selection, only some of which might be used. For example, if all traffic to or from a given interface is to be intercepted, one would configure an entry which lists the interface, and wild-card everything else. If all traffic to or from a given IP Address is to be intercepted, one would configure two such entries listing the IP Address as source and destination respectively, and wild-card everything else. If a particular voice on a teleconference is to be intercepted, on the other hand, one would extract the multicast (destination) IP address, the 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 intercepted traffic will be diverted to. The second index permits multiple classifiers to be used together, such as having an IP address as source or destination.

The interface may be physical or virtual. If this is the only parameter specified, 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 interface that routing chooses. Some platforms may not implement the entire range of options."

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.
