CTRON-PRIORITY-EXTENSIONS-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 ctPriorityExt MIB is used to control priority packet forwarding.
-- Priority packet forwarding provides the ability to designate certain 
-- packets to be of higher importance than others.  This control allows
-- for the forwarding of higher priority packets before those of lower priority.
-- This functionality is essential for time critical applications on 
-- shared networks. 



ctPriorityExtTxQueue  OBJECT IDENTIFIER
   ::= { ctPriorityExt 1 }

-- The ctPriorityExtTxQueue group specifies the number of 
-- transmit queues supported for each physical interface on the device.
-- Which transmit queue a packet is placed on will be determined by
-- associating each priority level (0-7) with a particular transmit
-- queue. Specifically the priority mappings will be as follows:
--
--               +=====================================+
--               |Priority | Number of Transmit Queues |
