CISCO-IETF-MEGACO-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.

--    This group consists of all the configuration related

--   The Media Gateway Controller Table... 
-- 
--   This table would provide information about the media gateway  
--   controllers in the network and their configuration. The rules 
--   that guide this table are: 
-- 
--   (1) This table consists a 'List' of Media Gateway Controllers  
--       (on a media gateway), and Configuration Information for 
--       these  Controllers. 
-- 
--   (2) An Entry in this Table is automatically created when a 
--       manager creates an entry in the cmedGatewayConfigTable
--       because even though the same MGC could manage many gateways,
--       they could have different logical IP address/Port number 
--       towards each of the gateway 
--
--   (3) There can be many logical gateways inside a physical 
--       gateway (cmedGatewayId) and there can be multiple media
--       gateway controllers (cmedGwyControllerId) and there can be
--       many links between "m" number of gateways and "n" number of 
--       controllers (cmedGatewayLinkId).
--          
--       The relationship can be, for example, as follows:
--
--      cmedGatewayId                       cmedGwyControllerId

-- 
--   The Media Gateway Property Profile Table... 
-- 
--   This table describes different profiles and the properties 
--   supported by each profile. The rules that guide this table are: 
-- 
--   (1) There are 'N' entries for each Gateway-PropertyProfile 
--   (2) Each entry is a supported property, thus this table gives 
--       a list of supported properties for each specified Profile. 
--   (3) Each Property is defined as an Object Identifier in the
--       various Package Mibs (like MEGACO-TONES-MIB etc).   
--   (4) That OID is used to identify the particular Package, 
--       and if the  Termination supports the property, this 
--       Package OID is included  in its list. 
--   (5) Terminations (in the TerminationsTable) will have a 
--       PropertyProfileId that indicates which PropertyProfile this 
--       Termination supports.  
--   (6) A Manager builds a Profile of properties, then ties each  
--       termination to a defined profile, via the PropertyProfileId 
--   (7) Vendors are encouraged to come up with different profiles 
--       for different scenarios in order to ensure 
--       inter-operability among different implementations
