|
|
|
# Let SNMP::Info determine the correct subclass for you.
|
|
my $baystack = new SNMP::Info(
|

AutoSpecify => 1,
|
|

=head1 DESCRIPTION
|
|
|
|
Provides abstraction to the configuration information obtainable from a Nortel
|
|
Ethernet Switch (Baystack) 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 $baystack->vendor()

|

Returns 'nortel'

=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>.

|
|
|
|
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.

=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.

|
=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.

|
|
|
=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().

|
|
|
|
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().

|
|
=head2 Topology information
|
|
|
|
Based upon the software version devices may support SynOptics Network
|
|
Management Protocol (SONMP) and Link Layer Discovery Protocol (LLDP). These
|
|
methods will query both and return the combination of all information. As a
|
|
result, there may be identical topology information returned from the two
|
|
protocols causing duplicate entries. It is the calling program's
|
|
responsibility to identify any duplicate entries and remove duplicates if
|
|
necessary.
|
|
|
|
=over
|
|
|
|
=item $baystack->hasCDP()
|
|
|
|
Returns true if the device is running either SONMP or LLDP.
|
|
|
|
=item $baystack->c_if()
|
|
|
|
Returns reference to hash. Key: iid Value: local device port (interfaces)
|
|
|
|
=item $baystack->c_ip()
|
|
|
|
Returns reference to hash. Key: iid Value: remote IPv4 address
|
|
|
|
If multiple entries exist with the same local port, c_if(), with the same IPv4
|
|
address, c_ip(), it may be a duplicate entry.
|
|
|
|
If multiple entries exist with the same local port, c_if(), with different
|
|
IPv4 addresses, c_ip(), there is either a non-SONMP/LLDP device in between two or
|
|
more devices or multiple devices which are not directly connected.
|
|
|
|
Use the data from the Layer2 Topology Table below to dig deeper.
|
|
|
|
=item $baystack->c_port()
|
|
|
|
Returns reference to hash. Key: iid Value: remote port (interfaces)
|
|
|
|
=item $baystack->c_id()
|
|
|
|
Returns reference to hash. Key: iid Value: string value used to identify the
|
|
chassis component associated with the remote system.
|
|
|
|
=item $baystack->c_platform()
|
|
|
|
Returns reference to hash. Key: iid Value: Remote Device Type
