NAME
         variables - Format of specifying variable names to  SNMP
     tools.

SYNOPSIS
         system.sysdescr.0

DESCRIPTION
     Variable names are  in  the  format  of  Object  Identifiers
     (ASN.1).   There are several methods of representation. Each
     variable name is given in the format of A.B.C.D..., where A,
     B,  C, and D are subidentifiers in one of two forms of nota-
     tion.  Each  subidentifier  may  be  encoded  as  a  decimal
     integer,  or a symbol as found in the RFC1066 MIB.  The case
     of the symbols is not significant.
     If there is no leading "." in the variable  name,  the  name
     will   be   formed   as   if   having   been  preceded  with
     "iso.org.dod.internet.mgmt.mib.".   A  "."  must  be  placed
     before  the  first  variable if the user is to fully specify
     the name.  For example:

     _1._1._0 _s_y_s_t_e_m._s_y_s_D_e_s_c_r._0 _a_n_d _1._s_y_s_D_e_s_c_r._0

     all refer to the same variable name.  Likewise:

     ._1._3._6._1._2._1._1._1._0
     ._i_s_o._o_r_g._d_o_d._i_n_t_e_r_n_e_t._m_g_m_t._m_i_b._s_y_s_t_e_m._s_y_s_d_e_s_c_r._0
     ._1._3._6._1._2._1._1._s_y_s_d_e_s_c_r._0

     All refer to the same variable name.

     The description of the variables in the MIB is  given  in  a
     file  named  _m_i_b._t_x_t  in  the current directory or in a file
     named in the environment variable _M_I_B_F_I_L_E _o_r _i_n /_e_t_c/_m_i_b._t_x_t
     .  These  files  are searched in the above order.  The files
     are in the ASN.1 notation and  use  the  OBJECT  TYPE  macro
     defined  in  RFC  1065.  Most of the file describing the RFC
     1066 MIB is pulled out of RFC 1066 without change.

SEE ALSO
     RFC 1065, RFC 1066, RFC 1067, ISO IS 8824(ASN.1)

BUGS
     The parser of the _m_i_b._t_x_t file is  not  expected  to  handle
     bizarre  (although  correct)  interpretations  of  the ASN.1
     notation.
