CISCO-ENHANCED-WRED-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 WRED MIB - Overview
                 Cisco Weighted Random Early Detection/Drop (WRED)
                 is a method which avoids traffic congestion on an
                 output interface. Congestion is detected by computing
                 the average output queue size against queue
                 thresholds, which can be configured either per IP
                 precedence or differentiated services code point
                 (DSCP) based. WRED support are on the IP fast
                 switching and IP flow switching only. It does not
                 apply to IP process switching.

                 The purpose of this MIB is to provide Weighted Random
                 Early Detection/Drop packet configuration and packet
                 filtering information. This MIB provides the WRED
                 information about  the transmit (Tx) side and 
                 receive (Rx) side of the modules, for the managed
                 systems that support WRED on both transmit side 
                 and receive side."
