=head1 SYNOPSIS
|
|
|
|
# Let SNMP::Info determine the correct subclass for you.
|
|
my $baystack = new SNMP::Info(
|
|
AutoSpecify => 1,
|
|
Debug => 1,
|
|
DestHost => 'myswitch',

|
|
|
|
=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.

These are methods that return scalar value from SNMP

|
|
=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>.
|
|
|
|
=item $baystack->stp_ver()
|
|
|
|
Returns the particular STP version running on this device.
|
|
|
|
Values: C<nortelStpg>, C<pvst>, C<rstp>, C<mstp>, C<ieee8021d>

=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.

|
|
to a hash.

=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 $baystack->peth_port_ifindex()
|
|

Maps the C<pethPsePortTable> to C<ifIndex> by way of the F<ENTITY-MIB>.

=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.
