SYNOPSIS
    #Let SNMP::Info determine the correct subclass for you.

    my $bayhub = new SNMP::Info(
                          AutoSpecify => 1,
                          Debug       => 1,
                          DestHost    => 'myswitch',
                          Community   => 'public',
                          Version     => 2
                        )

    or die "Can't connect to DestHost.\n";

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

DESCRIPTION
Provides abstraction to the configuration information obtainable from a Bay hub device through SNMP. Also provides device MAC to port mapping through the proprietary MIB.

  Inherited Classes

SNMP::Info::Layer2
SNMP::Info::NortelStack
SNMP::Info::SONMP

  Required MIBs

S5-ETHERNET-COMMON-MIB
S5-COMMON-STATS-MIB

  Inherited MIBs
See "Required MIBs" in SNMP::Info::Layer2 for its MIB requirements.

See "Required MIBs" in SNMP::Info::NortelStack for its MIB requirements.

See "Required MIBs" in SNMP::Info::SONMP for its MIB requirements.

GLOBALS
These are methods that return scalar value from SNMP

$bayhub->vendor()
    Returns 'avaya'

$bayhub->os()
    Returns 'bay_hub'

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

    Removes either Baystack Hub, 5000, or 5005 depending on the model.

  Overrides

$bayhub->layers()
    Returns 00000011. Class emulates Layer 2 functionality through proprietary MIBs.

$bayhub->index_factor()
    Required by SNMP::Info::SONMP. Number representing the number of ports reserved per slot within the device MIB. Returns 256.

$bayhub->slot_offset()
    Required by SNMP::Info::SONMP. Offset if slot numbering does not start at 0. Returns 0.

See "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

$bayhub->i_index()
    Returns reference to map of IIDs to Interface index.

    Since hubs do not support "ifIndex", the interface index is created using the formula (board * 256 + port).

$bayhub->interfaces()
    Returns reference to map of IIDs to physical ports.

$bayhub->i_duplex()
    Returns half, hubs do not support full duplex.

$bayhub->i_duplex_admin()
    Returns half, hubs do not support full duplex.

$bayhub->i_speed()
    Returns interface speed.

$bayhub->i_up()
    Returns ("s5EnPortLinkStatus") for each port. Translates on/off to up/down.

$bayhub->i_up_admin()
    Returns ("s5EnPortPartStatus") for each port.

$bayhub->set_i_up_admin(state, ifIndex)
    Sets port state, must be supplied with state and port "ifIndex"

    State choices are 'up' or 'down'

    Example:
      my %if_map = reverse %{$bayhub->interfaces()};
      $bayhub->set_i_up_admin('down', $if_map{'1.1'})
          or die "Couldn't change port state. ",$bayhub->error(1);

$bayhub->bp_index()
    Simulates bridge MIB by returning reference to a hash containing the index for both the keys and values.

$bayhub->fw_port()
    Returns reference to map of IIDs of the "S5-COMMON-STATS-MIB::s5CmSNodeTable" to the Interface index.

$bayhub->fw_mac()
    ("s5CmSNodeMacAddr")

  Pseudo ENTITY-MIB Information
These devices do not support ENTITY-MIB. These methods emulate Physical Table methods using S5-CHASSIS-MIB. See "TABLE METHODS" in SNMP::Info::NortelStack for details.

$bayhub->e_index()
    Returns ns_e_index().

$bayhub->e_class()
    Returns ns_e_class().

$bayhub->e_descr()
    Returns ns_e_descr().

$bayhub->e_name()
    Returns ns_e_name().

$bayhub->e_fwver()
    Returns ns_e_fwver().

$bayhub->e_hwver()
    Returns ns_e_hwver().

$bayhub->e_parent()
    Returns ns_e_parent().

$bayhub->e_pos()
    Returns ns_e_pos().

$bayhub->e_serial()
    Returns ns_e_serial().

$bayhub->e_swver()
    Returns ns_e_swver().

$bayhub->e_type()
    Returns ns_e_type().

$bayhub->e_vendor()
    Returns ns_e_vendor().
