=head1 NAME
SNMP::Info::Layer2::Baystack - SNMP Interface to Avaya Ethernet Switch
(Baystack) and VSP 7000 series switches
=head1 AUTHOR
Eric Miller
=head1 SYNOPSIS
# Let SNMP::Info determine the correct subclass for you.
my $baystack = new SNMP::Info(
AutoSpecify => 1,
Debug => 1,
DestHost => 'myswitch',
Community => 'public',
Version => 2
)
or die "Can't connect to DestHost.\n";
my $class = $baystack->class();
print "SNMP::Info determined this device to fall under subclass : $class\n";
=head1 DESCRIPTION
Provides abstraction to the configuration information obtainable from an
Avaya Ethernet Switch (formerly Nortel/Bay Baystack) and VSP 7000 series
through SNMP.
For speed or debugging purposes you can call the subclass directly, but not
after determining a more specific class using the method above.

=item SNMP::Info::SONMP
=item SNMP::Info::NortelStack
=item SNMP::Info::RapidCity
=item SNMP::Info::LLDP

=head2 Inherited MIBs
See L<SNMP::Info::SONMP/"Required MIBs"> for its MIB requirements.
See L<SNMP::Info::NortelStack/"Required MIBs"> for its MIB requirements.
See L<SNMP::Info::RapidCity/"Required MIBs"> for its MIB requirements.

See L<SNMP::Info::Layer3/"Required MIBs"> for its MIB requirements.
=head1 GLOBALS
These are methods that return scalar value from SNMP
=over
=item $baystack->vendor()
Returns 'avaya'
=item $baystack->model()
Cross references $baystack->id() to the F<SYNOPTICS-MIB> and returns
the results. 303s and 304s have the same ID, so we have a hack
to return depending on which it is.
Returns BPS for Business Policy Switch
For others extracts and returns the switch numeric designation.
=item $baystack->os()
Returns 'baystack' or 'boss' depending on software version.
=item $baystack->os_bin()
Returns the firmware version extracted from C<sysDescr>.
=back
=head2 Overrides
=over
=item $baystack->index_factor()
Required by SNMP::Info::SONMP. Number representing the number of ports
reserved per slot within the device MIB.
Index factor on the Baystack switches are determined by the formula: Index
Factor = 64 if (model = 470 or (os eq 'boss' and operating in pure mode))
or else Index factor = 32.
Returns either 32 or 64 based upon the formula.

=head1 TABLE METHODS
These are methods that return tables of information in the form of a reference
to a hash.
=head2 Overrides
=over
=item $baystack->interfaces()
Returns reference to the map between IID and physical Port.
Slot and port numbers on the Baystack switches are determined by the
formula:
port = (Interface index % Index factor)
slot = (int(Interface index / Index factor)) + Slot offset
The physical port name is returned as slot.port.
=item $baystack->i_ignore()
Returns reference to hash of IIDs to ignore.
=item $baystack->i_mac()
Returns the C<ifPhysAddress> table entries.
Removes all entries matching '00:00:00:00:00:00' -- Certain
revisions of Baystack firmware report all zeros for each port mac.
=item $baystack->i_name()
Crosses C<ifName> with C<ifAlias> and returns the human set port name if
exists.
=item $poe->peth_port_ifindex()
Maps the C<pethPsePortTable> to C<ifIndex> by way of the F<ENTITY-MIB>.
=back
=head2 F<ENTITY-MIB> Information
For older devices which do not support F<ENTITY-MIB>, these methods emulate
Physical Table methods using F<S5-CHASSIS-MIB>. See
L<SNMP::Info::NortelStack/"TABLE METHODS"> for details on ns_e_* methods.
=over
=item $baystack->e_index()
If the device doesn't support C<entPhysicalDescr>, this will try ns_e_index().
Note that this is based on C<entPhysicalDescr> due to implementation
details of SNMP::Info::Entity::e_index().
=item $baystack->e_class()
If the device doesn't support C<entPhysicalClass>, this will try ns_e_class().
=item $baystack->e_descr()
If the device doesn't support C<entPhysicalDescr>, this will try ns_e_descr().
=item $baystack->e_name()
If the device doesn't support C<entPhysicalName>, this will try ns_e_name().
=item $baystack->e_fwver()
If the device doesn't support C<entPhysicalFirmwareRev>, this will try
ns_e_fwver().
=item $baystack->e_hwver()
If the device doesn't support C<entPhysicalHardwareRev>, this will try
ns_e_hwver().
=item $baystack->e_parent()
If the device doesn't support C<entPhysicalContainedIn>, this will try
ns_e_parent().
=item $baystack->e_pos()
If the device doesn't support C<entPhysicalParentRelPos>, this will try
ns_e_pos().
=item $baystack->e_serial()
If the device doesn't support C<entPhysicalSerialNum>, this will try
ns_e_serial().
=item $baystack->e_swver()
If the device doesn't support C<entPhysicalSoftwareRev>, this will try
ns_e_swver().
=item $baystack->e_type()
If the device doesn't support C<entPhysicalVendorType>, this will try
ns_e_type().
=item $baystack->e_vendor()
If the device doesn't support C<entPhysicalMfgName>, this will try
ns_e_vendor().
