=head1 NAME
SNMP::Info::Layer2::Bay - SNMP Interface to old Bay Network BayStack Switches
=head1 AUTHOR
Max Baker
=head1 SYNOPSIS
This module is Deprecated. Please use Layer2::BayStack instead.
=head1 DESCRIPTION
Provides abstraction to the configuration information obtainable from a
Bay device 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.
my $bay = new SNMP::Info::Layer2::Bay(...);
=head2 Inherited Classes
=over
=item SNMP::Info::Layer2
=back
=head2 Required MIBs
=over
=item F<SYNOPTICS-ROOT-MIB>
=item F<S5-ETH-MULTISEG-TOPOLOGY-MIB>
=item Inherited classes
MIBs required by L<SNMP::Info::Layer2/"Required MIBs"> and its superclasses.
=back
=head1 GLOBALS
These are methods that return scalar value from SNMP
=over
=item $bay->vendor()
Returns 'bay' :)
=item $bay->model()
Cross references $bay->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.
Removes C<sreg-> from the model name
=item $baystack->os()
Returns 'bay'.
=item $bay->os_ver()
Returns the os version extracted from C<sysDescr>.
=item $bay->os_bin()
Returns the firmware version extracted from C<sysDescr>.
=item $bay->cdp_id()
Returns the IP that the device is sending out for its Nmm topology info.
(C<s5EnMsTopIpAddr>)
=item $bay->cdp_run()
Returns if the F<S5-ETH-MULTISEG-TOPOLOGY> info is on for this device.
(C<s5EnMsTopStatus>)
=back
=head2 Globals imported from SNMP::Info::Layer2
See documentation in L<SNMP::Info::Layer2/"GLOBALS"> for details.
=head1 TABLE METHODS
These are methods that return tables of information in the form of a reference
to a hash.
=head2 Overrides
=over
=item $bay->interfaces()
Returns reference to map of IIDs to physical ports.
Currently simply returns the C<ifIndex>
=item $bay->i_ignore()
Returns reference to hash of IIDs to ignore.
Simply calls the SNMP::Info::Layer2::i_ignore() for this.
=item $bay->i_mac()
Returns the C<ifPhysAddress> table entries.
Removes all entries matching '00:00:00:00:00:00' -- Certain
older revisions of Bay 303 and 304 firmware report all zeros
for each port mac.
=back
=head2 Pseudo CDP information
All entries with port=0 are local and ignored.
=over
=item $bay->c_if()
Returns reference to hash. Key: port.1 Value: port (iid)
=item $bay->c_ip()
Returns reference to hash. Key: port.1
The value of each hash entry can either be a scalar or an array.
A scalar value is most likely a direct neighbor to that port.
It is possible that there is a non-bay device in between this device and the
remote device.
An array value represents a list of seen devices. The only time you will get
an array of neighbors, is if there is a non-bay device in between two or more
devices.
Use the data from the Layer2 Topology Table below to dig deeper.
=item $bay->c_port()
Returns reference to hash. Key: IID, Value: Remote port (interfaces)
=item $bay->c_platform()
Returns reference to hash. Key: IID, Value: Remote device type
=item $bay->port()
Returns reference to hash. Key: port.1 Value: port
=item $bay->platform()
Returns reference to hash. Key: port.1 Value: Remote Device Type
=back
=head2 Layer2 Topology info (C<s5EnMsTopNmmTable>)
=over
=item $bay->bay_topo_slot()
Returns reference to hash. Key: Table entry, Value:slot number
(C<s5EnMsTopNmmSlot>)
=item $bay->bay_topo_port()
Returns reference to hash. Key: Table entry, Value:Port Number
(interface iid)
(C<s5EnMsTopNmmPort>)
=item $bay->bay_topo_ip()
Returns reference to hash. Key: Table entry, Value:Remote IP address of entry
(C<s5EnMsTopNmmIpAddr>)
=item $bay->bay_topo_seg()
Returns reference to hash. Key: Table entry, Value:Remote Segment ID
(C<s5EnMsTopNmmSegId>)
=item $bay->bay_topo_mac
(C<s5EnMsTopNmmMacAddr>)
Returns reference to hash. Key: Table entry, Value:Remote MAC address
=item $bay->bay_topo_platform
Returns reference to hash. Key: Table entry, Value:Remote Device Type
(C<s5EnMsTopNmmChassisType>)
=item $bay->bay_topo_localseg
Returns reference to hash. Key: Table entry, Value:Boolean, if bay_topo_seg()
is local
