CISCO-MGC-MIB by vendor Cisco

CISCO-MGC-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
		"This MIB is used to support MGC(call agent) and 
                 MGC Group configuration. 
                 The MGC or MGC group configuration is performed 
                 under a specific gateway(cmgwIndex).

                 The call agent is an external element (outside
                 of gateway) with call control intelligence
                 to control call connection in gateway.
                 The protocols used for communication between voice 
                 gateway and call agent included SGCP, MGCP, ...

                 Multiple IP addresses can be associated with one 
                 call agent.
                
                 An MGC group is a logical grouping of several MGCs
                 into one group.

                 MGC redundancy is used to support multi call agent
                 for one gateway. With MGC redundancy, a voice 
                 gateway can send gateway-initiated-commands to the 
                 next MGC in the MGC group if it fails to receive 
                 response from any IP address(es) associated to the 
                 current MGC. 

                 To use MGC redundancy in gateway:
                 
                 Step 1: add individual entry (in any order) for

                   profile   
                   MGC 
   
                 Step 2: make association between the entries 
  
                 1   IP with MGC            
                 2   MGC with MGC group   
      
                 1/2 protocol with MGC group 

                 3   MGC group with profile   
                     or
                     MGC group with gateway

                  Only if a MGC group at least is associated with 
                  one profile or gateway, then the MGC group can be 
                  used, otherwise the MGC group is useless.

                  To delete the following entries, it is needed to 
                  do de-association first:

                    profile   
                    MGC      

                  When do de-association, the order is opposite to that
                  of association.

               external DNS name server.

         'externalOnly' means the IP address for this domain name 
               will be resolved externally using DNS name server.

         The request to change from 'internalOnly' to 'externalOnly'
         will be rejected if the DNS name server is not available
         for gateway.

         The IP addresses related to the same MGC should have the
         same cMgcResolution. The value of the MGC associated objects 
         in the cMgcIpConfigTable can not be modified by NMS if the 
         value of cMgcResolution for the MGC is 'externalOnly'.

         The following are the behavior of changing the value of this 
         object.

         [1] changing the value from  'externalOnly' to 'internalOnly'

         1) precondition
             MGC is not associated with any MGC group
             (value of cMgcNumMgcGroups is zero).

         2) behavior
             If the value of this object is changed successfully,
             all existing IP addresses in cMgcIpConfigTable that are 
             associated to the MGC will be removed automatically.
             Note that MGW can't communicate with MGC if NMS does not 
             add static IP address into cMgcIpConfigTable for the MGC.

         [2] changing the value from  'internalOnly' to 'externalOnly'

         1) precondition
             All MGC associated statically configured IP addresses 
             must be removed from cMgcIpConfigTable by NMS before  
             setting 'externalOnly' value to this object. 
             An inconsistentValue error is generated for setting
             'externalOnly' value if the MGC associated IP addresses 
              are not removed.
         2) behavior
             After successfully setting 'externalOnly' value to this 
             object, the MGC domain name will be resolved by MGW  
             software using external DNS name server and the resulting 
             IP addresses will be added to cMgcIpConfigTable 
             automatically.

         and profile/gateway with bitmap format.

         It is 1:N mapping, e.g., each profile or gateway can only 
         have one MGC group, but one MGC group can be associated 
         with multi profile and gateway.

         The possible bit positions used in the bitmap are listed as 
         follows:
