NAME
SNMP::Info::Layer2::Centillion - SNMP Interface to Nortel Centillion based ATM Switches

AUTHOR

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.

  Globals imported from SNMP::Info
See documentation in "GLOBALS" in SNMP::Info for details.

  Globals imported from SNMP::Info::Bridge
See documentation in "GLOBALS" in SNMP::Info::Bridge for details.

  Globals imported from SNMP::Info::NortelStack
See documentation in "GLOBALS" in SNMP::Info::NortelStack for details.

  Global Methods imported from SNMP::Info::SONMP
See documentation in "GLOBALS" in SNMP::Info::SONMP for details.

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()
    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")
