Nortel-Magellan-Passport-PorsAtmTrunksMIB 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.

-- Trunk/n PathAdmin AtmAccess
-- This subcomponent is optionally added to the PathAdmin 
-- component on ATM hardware. 
-- Without this subcomponent the PathAdmin will transport all Path 
-- Oriented traffic as AAL5 encapsulated cells on the Trunk 
-- AtmAccess localConnection VCC.
-- With this subcomponent added under the PathAdmin the PathAdmin 
-- will operate in one of two modes. These modes are referred to as 
-- mapping and multiplexing and the selection of the mode is done by 
-- setting the PathAdmin AtmAccess mode attribute to either mapping 
-- or multiplexing.
-- When the mode is set to mapping, the PathAdmin will create new 
-- VCCs for each new LCh that it sets up. In mapped mode the CPU 
-- usage is normally 0 for a connection and so the ATM FP can 
-- support a great many more mapped mode connections than it can 
-- multiplexed mode connections. Connections whose 
-- maximumTransmissionUnit is exactly 45 will use the SPO adaption 
-- layer to efficiently fit a single voice frame into a single cell with 
-- minimum overhead. All other connections will use the AAL5 
-- adaption layer protocol.
-- When the mode is set to multiplexing, the PathAdmin will look at 
-- the attribute atmConnection which points to a second provisioned 
-- ATM VCC. The PathAdmin will then multiplex voice frames onto 
-- this second VCC using a proprietary Short Path Oriented adaption 
-- layer which encapsulates one voice frame into one voice cell with 
-- low overhead. The PathAdmin will multiplex all non voice traffic 
-- over the Trunk/n AtmAccess atmConnection VCC using the AAL5 
-- protocol.
