=head1 SYNOPSIS
|
||||
|
||||
# Let SNMP::Info determine the correct subclass for you.
|
||||
my $baystack = new SNMP::Info(
|
||||
AutoSpecify => 1,
|
||||
Debug => 1,
|
||||
# These arguments are passed directly on 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 DESCRIPTION
|
||||
|
||||
Provides abstraction to the configuration information obtainable from a Nortel Networks'
|
||||
Baystack 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.

These are methods that return scalar value from SNMP
|

|

|

=item $baystack->vendor()
|
||||
|
||||
Returns 'Nortel'
|
||||
|
||||
=item $baystack->model()
|
||||
|
||||
Cross references $baystack->id() to the 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 sreg- from the model name
|
||||
|
||||
=item $baystack->os()
|
||||
|
||||
Returns 'Baystack' or 'BoSS' depending on software version.
|
||||
|
||||
=item $baystack->os_bin()
|
||||
|
||||
Returns the firmware version extracted from B<sysDescr>.

=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.

=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 B<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 ifName with ifAlias and returns the human set port name if exists.
