CISCO-SWITCH-USAGE-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.

        DESCRIPTION
                "This MIB defines objects related to statistics 
                for the usage of switch fabric. The switch fabric
                is used by the incoming packets from the line/network
                to a interface. Such packets are called ingress packets.
                Counters are maintained for number of ingress packets/
                octets switched by the switch fabric for each 
                interface.
                NOTE: These counters are not counting the total number 
                of incoming packets and octets for a particular 
                interface. Instead only the counts of packets and 
                octets that actually use the switch-fabric are being
                accounted for by this MIB.  Therefore, the counters in 
                this MIB are distinctly different from packet and octet 
                counters found in the IF-MIB."
