<description>
<p>The module <c>snmp_target_mib</c> implements the instrumentation
functions for the SNMP-TARGET-MIB,
and functions for configuring the database. </p>
<p>The configuration files are described in the SNMP User's Manual.</p>
<p>Legacy API functions <c>add_addr/10</c> that does not specify
transport domain, and <c>add_addr/11</c> that has got separate
<c>IpAddr</c> and <c>PortNumber</c> arguments still work as before
for backwards compatibility reasons.</p>
