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";

my $class = $baystack->class();
print "SNMP::Info determined this device to fall under subclass : $class\n";

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.

my $baystack = new SNMP::Info::Layer2::Baystack(...);

GLOBALS

These are methods that return scalar value from SNMP

$baystack->vendor()

Returns 'Nortel'

$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

$baystack->os()

Returns 'Baystack' or 'BoSS' depending on software version.

$baystack->os_bin()

Returns the firmware version extracted from sysDescr.

Overrides

$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.

TABLE ENTRIES

These are methods that return tables of information in the form of a reference to a hash.

Overrides

$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.
$baystack->i_ignore()

Returns reference to hash of IIDs to ignore.

$baystack->i_mac()

Returns the 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.

$baystack->i_name()

Crosses ifName with ifAlias and returns the human set port name if exists.
