SNMP::Info::Layer3::Tasman - SNMP Interface to Avaya Secure Routers
=head1 AUTHOR
Eric Miller
=head1 SYNOPSIS
# Let SNMP::Info determine the correct subclass for you.
my $tasman = new SNMP::Info(
AutoSpecify => 1,
Debug => 1,
# These arguments are passed directly to SNMP::Session
DestHost => 'myswitch',
Community => 'public',
Version => 2
)
or die "Can't connect to DestHost.\n";

print "SNMP::Info determined this device to fall under subclass : $class\n";

=head1 GLOBALS
These are methods that return scalar values from SNMP
=over
=item $tasman->vendor()
Returns C<'avaya'>
=item $tasman->model()
Tries to get the model from C<nnchassisModel> and if not available
cross references $tasman->id() to F<NT-ENTERPRISE-DATA-MIB>.
Substitutes 'SR' for C<'ntSecureRouter'> in the name for readability.
=item $tasman->os()
Returns C<'tasman'>
=item $tasman->os_ver()
Grabs the os version from C<nnsysVersion>

=item $tasman->serial()
Tries both (C<nnchassisOperStatus>) and (C<nnchassisSerialNumber>) as oid

=head1 TABLE METHODS
These are methods that return tables of information in the form of a reference
to a hash.
=over 4
=item $tasman->i_duplex_admin()
Returns reference to hash of iid to administrative duplex setting.
First checks for fixed gigabit ports which are always full duplex. Next checks
the port administrative speed (C<portAdminSpeed>) which if set to
autonegotiate then the duplex will also autonegotiate, otherwise it uses the
reported port duplex (C<portDuplex>).
=item $tasman->i_speed_admin()
Returns reference to hash of iid to administrative speed setting.
C<portAdminSpeed>
=back
=head2 Pseudo F<ENTITY-MIB> information
These methods emulate F<ENTITY-MIB> Physical Table methods using
F<CHASSIS-MIB>.
=over
=item $tasman->e_index()
Returns reference to hash. Key: IID, Value: Integer.
=item $tasman->e_class()
Returns reference to hash. Key: IID, Value: General hardware type.
=item $tasman->e_descr()
Returns reference to hash. Key: IID, Value: Human friendly name
=item $tasman->e_vendor()
Returns reference to hash. Key: IID, Value: avaya
=item $tasman->e_serial()
Returns reference to hash. Key: IID, Value: Serial number
=item $tasman->e_pos()
Returns reference to hash. Key: IID, Value: The relative position among all
entities sharing the same parent.
=item $tasman->e_type()
Returns reference to hash. Key: IID, Value: Type of component/sub-component.
=item $tasman->e_parent()
Returns reference to hash. Key: IID, Value: The value of e_index() for the
entity which 'contains' this entity. A value of zero indicates this entity
is not contained in any other entity.
=item $entity->e_fru()
BOOLEAN. Is a Field Replaceable unit?
