SYNOPSIS

 # Let SNMP::Info determine the correct subclass for you. 
 my $centillion = new SNMP::Info(
                          AutoSpecify => 1,
                          Debug       => 1,
                          DestHost    => 'myswitch',
                          Community   => 'public',
                          Version     => 2
                        ) 
    or die "Can't connect to DestHost.\n";

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

DESCRIPTION

Provides abstraction to the configuration information obtainable from a Centillion 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 $centillion = new SNMP::Info::Layer2::centillion(...);

Note: This class supports version 4.X and 5.X which are VLAN based rather than bridge group based.

GLOBALS

These are methods that return scalar value from SNMP

$centillion->vendor()

Returns 'Nortel'

$centillion->model()

Cross references $centillion->id() to the SYNOPTICS-MIB and returns the results.

Removes sreg- from the model name

$centillion->os()

Returns 'Centillion'

$centillion->tftp_action()

(sysTFTPStart)

$centillion->tftp_host()

(sysTFTPIpAddress)

$centillion->tftp_file()

(sysTFTPFileName)

$centillion->tftp_type()

(sysTFTPFileType)

$centillion->tftp_result()

(sysTFTPResult)

Overrides

$centillion->layers(): Returns 00000011. Class emulates Layer 2 functionality through proprietary MIBs.
$centillion->index_factor(): Required by SNMP::Info::SONMP. Number representing the number of ports reserved per slot within the device MIB. Returns 256.
$centillion->slot_offset(): Required by SNMP::Info::SONMP. Offset if slot numbering does not start at 0. Returns 0.

TABLE METHODS

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

Overrides

$centillion->interfaces()

    Returns reference to the map between IID and physical Port.

    Slot and port numbers on the Passport switches are determined by the
    formula:
      port = index % 256
      slot = int(index / 256)
 
    The physical port name is returned as slot.port.

$centillion->i_duplex()

Returns reference to map of IIDs to current link duplex

$centillion->i_duplex_admin()

Returns reference to hash of IIDs to admin duplex setting

$centillion->i_ignore()
