CISCO-PORT-QOS-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
                "Cisco PORT QOS MIB - Overview

                This MIB module is for the management of Cisco's
                per port rate-limiting and traffic shaping on L3
                switch/Router Platform(s).

                Per-port rate-limiting is a traffic control method.
                A set of rate limits are applied to the traffic
                traversing an interface. Each rate limit has a
                configurable action that is taken when rate
                limiting criteria is met.

                Per-port traffic shaping is a traffic control
                method. The user can restrict the amount of traffic
                coming out of a physical port. Excess traffic is 
                buffered within the router/switch to the extent 
                possible.

                This MIB module also provides per port QoS statistics."
