CISCO-FC-MULTICAST-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.

cfmMulticastRootTable OBJECT-TYPE
    SYNTAX      SEQUENCE OF CfmMulticastRootEntry
    MAX-ACCESS  not-accessible
    STATUS      current
    DESCRIPTION
           "This table allows the users to configure and monitor the
           FC Multicast parameters on all the VSANs configured on the 
           local switch.

           An entry is automatically created in this table if there
           is an entry in the fspfTable (defined in CISCO-FSPF-MIB) and
           fspfOperStatus (defined in CISCO-FSPF-MIB) for that
           entry is 'up'.
 
           An entry is automatically deleted from this table if
           either :
            a) the fspfOperStatus in the fspfTable entry for the 
               corresponding VSAN changes to 'down'.
                                 or
            b) the fspfTable entry for the corresponding VSAN is
               deleted.

           Entries in this table can be created via 
           cfmMulticastRootRowStatus only as the means to specify 
           non-default parameter values for a VSAN either because the
           VSAN is suspended or fspfOperStatus (defined in 
           CISCO-FSPF-MIB) for that VSAN is 'down' (VSAN state is 
           indicated by object vsanOperState which is defined in 
           CISCO-VSAN-MIB).

           So an entry in this table exists when one or both of these
           conditions holds:
           - one or more configuration parameters have non-default
             values for a VSAN which is either suspended or the 
             fspfOperStatus for that VSAN is down.  
           - the fspfOperStatus for VSAN is 'up'.

           This has a number of consequences:
           - an entry exists for a suspended VSAN whenever that VSAN 
             has non-default parameters.
           - an entry cannot be created (via cfmMulticastRootRowStatus) 
             for a VSAN with default parameters; instead, the agent
             creates/deletes an entry for a VSAN with default
             parameters according to whether the fspfOperStatus is 'up' 
             or 'down'.
           - an entry can not be created via cfmMulticastRootRowStatus 
             unless non-default parameter values are (simultaneously) 
             configured for a VSAN whose fspfOperStatus is 'down'.
           - deleting an entry via cfmMulticastRootRowStatus when either
             the VSAN is suspended and configured with non-default 
             values or the VSAN is active, is equivalent to resetting
             its parameters to their default values.
             If an entry is configured with default-values and the 
             VSAN is in suspended state, then the entry would be 
             deleted."
