NACL::CS::SystemSnmpCommunity

=head1 DESCRIPTION

C<NACL::CS::SystemSnmpCommunity> is a derived class of
L<NACL::CS::ComponentState::ONTAP|lib-NACL-CS-ComponentState-ONTAP-pm>. It represents the
state of an ONTAP SystemSnmpCommunity.  A related class is
L<NACL::C::SystemSnmpCommunity|lib-NACL-C-SystemSnmpCommunity-pm>, which represents access
to an ONTAP SystemSnmpCommunity.

=head2 fetch

    my $SystemSnmpCommunity_state   = NACL::CS::SystemSnmpCommunity->fetch(command_interface => $ci, ...);
	my @SystemSnmpCommunity_states = NACL::CS::SystemSnmpCommunity->fetch(command_interface => $ci, ...);

(Class method)
Discovers which elements are present and returns their state in ComponentState
objects. Called in scalar context it returns only one state object, in list
context it returns all state objects.
See L<NACL::CS::ComponentState|lib-NACL-CS-ComponentState-pm/fetch> for a
more detailed description along with a complete explanation of the options
it accepts.

Uses a CMode CLI APISet and 7Mode CLI APIset.
