SYNOPSIS

 # Let SNMP::Info determine the correct subclass for you. 
 my $centillion = 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      = $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 ENTRIES

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()
Returns reference to hash of IIDs to ignore.

$centillion->fw_mac()
(s5CmSNodeMacAddr)

$centillion->fw_port()
(s5CmSNodeIfIndx)

$centillion->bp_index()
Returns a mapping between ifIndex and the Bridge Table.

$centillion->i_vlan()
Returns a mapping between ifIndex and the VLAN.

Centillion 802.3 Extension Table (cnDot3ExtnTable)

$centillion->centillion_p_index()
Returns reference to hash. Maps table IIDs to Interface IIDs

(cnDot3ExtnIfIndex)

$centillion->centillion_p_duplex()
Returns reference to hash. Maps port operational duplexes to IIDs

(cnDot3ExtnIfOperConnectionType)

$centillion->rc_centillion_p_duplex_admin()
Returns reference to hash. Maps port admin duplexes to IIDs

(cnDot3ExtnIfAdminConnectionType)

Centillion VLAN Table (cnVlanPortMemberTable)

$centillion->centillion_i_vlan_index()
Returns reference to hash. Key: Table entry, Value: Index

(cnVlanPortMemberIfIndex)

$centillion->centillion_i_vlan()
Returns reference to hash. Key: Table entry, Value: VLAN ID

(cnVlanPortMemberVID)

$centillion->centillion_i_vlan_type()
Returns reference to hash. Key: Table entry, Value: VLAN Type

(cnVlanPortMemberIngressType)
