NAME

       snmp_view_based_acm_mib - Instrumentation Functions for SNMP-VIEW-BASED-ACM-MIB

DESCRIPTION

       The  module snmp_view_based_acm_mib implements the instrumentation functions for the SNMP-
       VIEW-BASED-ACM-MIB, and functions for configuring the database.

       The configuration files are described in the SNMP User's Manual.

EXPORTS

       configure(ConfDir) -> void()

              Types:

                 ConfDir = string()

              This function is called from the supervisor at system start-up.

              Inserts all data in the configuration files into the database and destroys all  old
              rows  with  StorageType volatile. The rows created from the configuration file will
              have StorageType nonVolatile.

              All snmp counters are set to zero.

              If an error is found in the configuration file, it is reported using  the  function
              config_err/2  of  the  error  report module, and the function fails with the reason
              configuration_error.

              ConfDir is a string which points to the directory where the configuration files are
              found.

              The configuration file read is: vacm.conf.

       reconfigure(ConfDir) -> void()

              Types:

                 ConfDir = string()

              Inserts  all data in the configuration files into the database and destroys all old
              data, including the rows with StorageType nonVolatile. The rows  created  from  the
              configuration file will have StorageType nonVolatile.

              Thus, the data in the SNMP-VIEW-BASED-ACM-MIB, after this function has been called,
              is the data from the configuration files.

              All snmp counters are set to zero.

              If an error is found in the configuration file, it is reported using  the  function
              config_err/2  of  the  error  report module, and the function fails with the reason
              configuration_error.

              ConfDir is a string which points to the directory where the configuration files are
              found.

              The configuration file read is: vacm.conf.

       add_sec2group(SecModel, SecName, GroupName) -> Ret

              Types:

                 SecModel = v1 | v2c | usm
                 SecName = string()
                 GroupName = string()
                 Ret = {ok, Key} | {error, Reason}
                 Key = term()
                 Reason = term()

              Adds  a  security  to  group  definition  to  the  agent  config. Equivalent to one
              vacmSecurityToGroup-line in the vacm.conf file.

       delete_sec2group(Key) -> Ret

              Types:

                 Key = term()
                 Ret = ok | {error, Reason}
                 Reason = term()

              Delete a security to group definition from the agent config.

       add_access(GroupName, Prefix, SecModel, SecLevel, Match, RV, WV, NV) -> Ret

              Types:

                 GroupName = string()
                 Prefix = string()
                 SecModel = v1 | v2c | usm
                 SecLevel = string()
                 Match = prefix | exact
                 RV = string()
                 WV = string()
                 NV = string()
                 Ret = {ok, Key} | {error, Reason}
                 Key = term()
                 Reason = term()

              Adds a access definition to the agent config. Equivalent to one vacmAccess-line  in
              the vacm.conf file.

       delete_access(Key) -> Ret

              Types:

                 Key = term()
                 Ret = ok | {error, Reason}
                 Reason = term()

              Delete a access definition from the agent config.

       add_view_tree_fam(ViewIndex, SubTree, Status, Mask) -> Ret

              Types:

                 ViewIndex = integer()
                 SubTree = oid()
                 Status = included | excluded
                 Mask = null | [integer()], where all values are either 0 or 1
                 Ret = {ok, Key} | {error, Reason}
                 Key = term()
                 Reason = term()

              Adds  a  view  tree  family  definition  to  the  agent  config.  Equivalent to one
              vacmViewTreeFamily-line in the vacm.conf file.

       delete_view_tree_fam(Key) -> Ret

              Types:

                 Key = term()
                 Ret = ok | {error, Reason}
                 Reason = term()

              Delete a view tree family definition from the agent config.
